[0032] Please refer to FIG. 1, the present disclosure provides a method for fabricating a liquid crystal display device 100. The method comprises the following steps.

[0033] Step 1: providing a liquid crystal display panel 10. The liquid crystal display panel 10 comprises a light-incident surface 111 and a light-emitting surface 121 on opposite sides thereof. Specifically, the liquid crystal display panel 10 comprises an array substrate 11, a color filter substrate 12, and a liquid crystal layer 15. The array substrate 11 and the color filter substrate 12 are disposed oppositely. The liquid crystal layer 15 is disposed between the array substrate 11 and the color filter substrate 12. The light-incident surface 111 of the liquid crystal display panel 10 is a surface of the array substrate 11 away from the liquid crystal layer 15. The light-emitting surface 121 of the liquid crystal display panel 10 is a surface of the color filter substrate 12 away from the liquid crystal layer 15.

[0034] Step 2: disposing a first polarizer 20 on the light-incident surface 111 of the liquid crystal display panel 10, and/or disposing a second polarizer 30 on the light-emitting surface 121 of the liquid crystal display panel 10. In an embodiment, the liquid crystal display panel 10 may only be provided with the first polarizer 20 or the second polarizer 30.

[0035] Specifically, the disposing the first polarizer 20 on the light-incident surface 111 comprises: coating an adhesive on the first polarizer 20 or the light-incident surface 111 to form an adhesive layer 8, and attaching the first polarizer 20 to the light-incident surface 111 through the adhesive layer 8. The disposing the second polarizer 30 on the light-emitting surface 121 comprises: coating the adhesive on the second polarizer 30 or the light-emitting surface 121 to form another adhesive layer 8, and attaching the second polarizer 30 to the light-emitting surface 121 through the adhesive layer 8. The adhesive may be a pressure-sensitive adhesive (PSA). The pressure-sensitive adhesive may be a polypropylene-based adhesive, but is not limited thereto.

[0036] In an embodiment, positions of the first polarizer 20 and the second polarizer 30 can be interchanged. That is, Step 2 may also be: disposing a first polarizer 20 on the light-emitting surface 121 of the liquid crystal display panel 10, and/or disposing a second polarizer 30 on the light-incident surface 111 of the liquid crystal display panel 10.

[0037] Step 3: directly forming a first anti-reflection film 40 on a surface of the first polarizer 20 away from the liquid crystal display panel 10 when the light-incident surface 111 is provided with the first polarizer 20, and directly forming a second anti-reflection film 50 on a surface of the second polarizer 30 away from the liquid crystal display panel 10 when the light-emitting surface 121 is provided with the second polarizer 30. Specifically, the first anti-reflection film 40 and the second anti-reflection film 50 may be formed by depositing an anti-reflection material on the first polarizer 20 and the second polarizer 30 by vacuum evaporation or sputtering, but are not limited thereto. The anti-reflection material may be a material with a low refractive index and high strength, such as magnesium fluoride. The first anti-reflection film 40 and the second anti-reflection film 50 may be formed of a same material or different materials.

[0038] In order to achieve a purpose of anti-reflection, a first thickness of the first anti-reflection film 40 may be adjusted based on a first refractive index of the first anti-reflection film 40 and a spectrum of a first light 101 emitted by a backlight panel, so that destructive interference occurs between lights reflected by upper and lower interfaces of the first anti-reflection film 40.

[0039] In order to achieve a better anti-reflection effect, a preferred first thickness e.sub.1 of the first anti-reflection film 40 may be calculated by the following formula (I).

[00001]$\begin{array}{cc}{e}_1=\frac{{\lambda }_1}{4\times n_1}& \mathrm{Formula}\left(I\right)\end{array}$

e.sub.1 is the first thickness of the first anti-reflection film 40, λ.sub.1 is a first wavelength of the first light 101, and n.sub.1 is the first refractive index of the first anti-reflection film 40.

[0040] Generally, refractive indexes of glass substrates and polarizers are about 1.52, and a refractive index of air is 1. Therefore, the first refractive index of the first anti-reflection film 40 is preferably 1.23 to 1.38, but is not limited thereto. The first reflectivity may be adjusted by changing a material of the first anti-reflection film 40. The first wavelength may be a wavelength of the first light 101 that mainly provides brightness of the liquid crystal display device 10. That is, the anti-reflection is performed on a wavelength that the backlight panel mainly provides the brightness of the liquid crystal display device 10. Wavelengths of commonly used backlight panels that mainly provide the brightness of the liquid crystal display device 10 are 450 nm and 500 nm-630 nm. Therefore, the first wavelength of the first light 101 may be 450 nm or 500 nm-630 nm, but is not limited thereto. The first wavelength may be adjusted by changing a spectrum of the backlight panel. When the first refractive index is 1.23 to 1.38, and the wavelength of the first light 101 is 450 nm or 500 nm to 630 nm, the first thickness of the first anti-reflection film 40 is preferably 81.5 nm to 128 nm, but is not limited thereto.

[0041] For example, when the first wavelength λ.sub.1 is 450 nm, if the first refractive index n.sub.1 is set to 1.23, the first thickness e.sub.1 is preferably 91.44 nm; and if the first refractive index n.sub.1 is set to 1.38, the first thickness e.sub.1 is preferably 81.5 nm. When the first wavelength λ.sub.1 is 500 nm, if the first refractive index n.sub.1 is set to 1.23, the first thickness e.sub.1 is preferably 101.6 nm; and if the first refractive index n.sub.1 is set to 1.38, the first thickness e.sub.1 is preferably 90.6 nm. When the first wavelength λ.sub.1 is 550 nm, if the first refractive index n.sub.1 is set to 1.23, the first thickness e.sub.1 is preferably 111.8 nm; and if the first refractive index n.sub.1 is set to 1.38, the first thickness e.sub.1 is preferably 99.7 nm. When the first wavelength κ.sub.1 is 630 nm, if the first refractive index n.sub.1 is set to 1.23, the first thickness e.sub.1 is preferably 128 nm; and if the first refractive index n.sub.1 is set to 1.38, the first thickness e.sub.1 is preferably 114.2 nm.

[0042] Similarly, in order to achieve the purpose of the anti-reflection, a second thickness of the second anti-reflection film 50 may be adjusted based on a second refractive index of the second anti-reflection film 50 and a transmission spectrum of a second light 102 penetrating the liquid crystal display device 10, so that destructive interference occurs between lights reflected by upper and lower interfaces of the second anti-reflection film 50.

[0043] In order to achieve a better anti-reflection effect, a preferred second thickness e.sub.z of the second anti-reflection film 50 may be calculated by the following formula (II).

[00002]$\begin{array}{cc}{e}_2=\frac{{\lambda }_2}{4\times n_2}& \mathrm{Formula}\left(\mathrm{II}\right)\end{array}$

e.sub.2 is the second thickness of the second anti-reflection film 50, λ.sub.2 is a second wavelength of the second light 102, and n.sub.2 is the second refractive index of the second anti-reflection film 50.

[0044] As mentioned above, generally, refractive indexes of glass substrates and polarizers are about 1.52, and a refractive index of air is 1. Therefore, the second refractive index of the second anti-reflection film 50 is preferably 1.23 to 1.38, but is not limited thereto. The second reflectivity may be adjusted by changing a material of the second anti-reflection film 50. The second wavelength may be a wavelength of the second light 102 mainly passing through the liquid crystal display device 10. That is, the anti-reflection is performed on a wavelength of the brightness mainly generated by the liquid crystal display device 10. According to transmission spectrums of commonly used liquid crystal display devices, reducing a reflection of green light with a wavelength of 540 nm to 560 nm can significantly improve a transmittance. Therefore, the second wavelength of the second light 102 may be 540 nm to 560 nm, but is not limited thereto. The second wavelength may be adjusted by changing a transmission spectrum of the liquid crystal display device 10. When the second refractive index is 1.23 to 1.38, and the second wavelength of the second light 102 is 540 nm to 560 nm, the second thickness of the second anti-reflection film 50 is preferably 97.8 nm to 113.8 nm, but is not limited thereto.

[0045] For example, when the second wavelength κ.sub.z is 540 nm, if the second refractive index n.sub.2 is set to 1.23, the second thickness e.sub.2 is preferably 109.8 nm; and if the second refractive index n.sub.2 is set to 1.38, the second thickness e.sub.2 is preferably 97.8 nm. When the second wavelength λ.sub.2 is 560 nm, if the second refractive index n.sub.2 is set to 1.23, the second thickness e.sub.2 is preferably 113.8 nm; and if the second refractive index n.sub.2 is set to 1.38, the second thickness e.sub.2 is preferably 101.4 nm.

The second polarizer 30 comprises an optical compensation film 31, a polarizing layer 32, a protective layer 33, and a hardened layer 34 in sequence.
