In the display device according to an embodiment, optical functional elements such as a prism sheet and a light diffusion layer are combined, and an optical composite sheet to which a light absorbing layer that selectively absorbs light of a specific wavelength band is inserted is used, so that the color gamut can be enhanced as compared with the prior art.

In the optical composite sheet according to an embodiment, optical functional elements such as a prism sheet and a light diffusion layer are combined, and a light absorbing layer that selectively absorbs light of a specific wavelength band is inserted, so that the optical performance and color gamut can be enhanced as compared with the prior art. In particular, it is possible to minimize the decrease in luminance due to the absorption of light by the light absorbing layer while enhancing the color gamut by adjusting the lamination configuration of the optical composite sheet.

A projector display system comprises a projector and a laminate glass panel comprising first and second glass layers and an assembly of interlayers sandwiched therebetween. The first glass layer is substantially parallel to the second glass layer and the assembly of interlayers includes a reflective polarizer film. The reflective polarizer film of the laminate glass panel has a predetermined range of incident angles defined by an upper limit and a lower limit, wherein when the image is projected onto the laminate glass panel at an incident angle within the predetermined range of incident angles, the reflective polarizer film is adapted to reflect a minimum threshold amount of a first polarized light component of the said image. The projector projects an image onto the laminate glass panel at a selected incident angle that is at least 30° less than the lower limit of the said predetermined range of incident angles.

The present invention pertains to a one-side-protected polarizing film having a transparent protective film on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 μm or less, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P>−(10.sup.0.929T−42.4−1)×100 (provided that T<42.3) or P≧99.9 (provided that T≧42.3); and the other surface of the polarizer has a transparent resin layer having a thickness of 0.2 μm or more and formed from a layer-forming material including a polyvinyl alcohol-based resin. Even when the polarizer has prescribed optical properties and the thickness is 10 μm or less, this one-side-protected polarizing film is capable of suppressing the occurrence of through cracks and nano-slits.

A composite functional polarized lens is a polarized lens in which lens substrate layers made of, for example, an allyl diglycol carbonate resin (produced by PPG Industries: CR-39), an urethane resin or other predetermined resin are integrally formed on both front and back surfaces of a polarizing film by way of insert molding, wherein a first lens substrate layer formed on the front surface of both the front and back surfaces of the polarizing film contains a light absorber which is an ultraviolet absorber, an infrared absorber, photochromic light absorber or a thermochromic light absorber as an additional component, and a second lens substrate layer formed on the back surface does not contain the light absorber.

The present invention relates to a polarizing plate and a liquid crystal display device. In the present invention, the polarizing plate is lightweight and has a small thickness and excellent properties including durability, water resistance, workability, pressure-sensitive adhesion and light leakage prevention ability; and the liquid crystal display device including the same are provided.

A display device includes a liquid crystal display panel (3) and a backlight source (2), and further includes a plurality of bandpass filters (1) corresponding to respective pixel units of the liquid crystal display panel (3), the bandpass filters (1) being configured to perform narrowband filtering on the light emergent from the backlight source (2). By adopting the bandpass filters (1), the narrowband filtering on the red, green and blue light is realized by using a narrowband interference filtering method, such that the effect of improving the gamut of the display device is achieved and the high-gamut display is realized.

The present application relates to a liquid crystal composition, a polarizing element and a use of the polarizing element. Since the polarizing element may be prepared by a simple coating process, the guest host type liquid crystal composition of the present application allows not only for reducing the manufacturing cost and lightweight thinning of the polarizing element, but also for manufacturing the polarizing element showing an excellent heat resistant stability without changes of absorption spectrum to transmission spectrum even in a severe condition such as high temperature environment. Such a polarizing element can be applied to various display devices such as liquid crystal display devices, EL display devices, field emission display devices, display devices using electronic papers, projection display devices or piezoelectric ceramic display devices.
