[Summary]

The present invention relates to an anti-glare film and a display apparatus, and more particularly to an anti-glare film including: a light-transmitting substrate; and a hard coating layer containing a binder resin, organic fine particles and inorganic fine particles dispersed in the binder resin, wherein a ratio of two or more organic fine particles aggregating with each other in the whole organic fine particles is 5% or less, and wherein a ratio of internal haze to external haze is 2.5 or less, and a display apparatus including the anti-glare film.

A film (1) includes hollow particles (10) and a binder (20). The hollow particles are made of a material having a refractive index of 1.15 to 2.70. The binder (20) is formed of at least a polysilsesquioxane and binds the hollow particles (10). The film (1) satisfies at least one of requirements Ib/Ia0.7 and Ib/Ic0.3. Ia is an absorbance derived from a hydrocarbon group not directly bonded to a silicon atom, the absorbance being determined by attenuated total reflection using a Fourier transform infrared spectrophotometer. Ib is an absorbance derived from a bond between a silicon atom and a non-reactive functional group. Ic is an absorbance derived from a bond between a silicon atom and a hydroxy group.

An optical filter (1a) includes a light-absorbing layer (10). The light-absorbing layer absorbs light in at least a portion of the near-infrared region. When light with a wavelength of 300 to 1200 nm is incident on the optical filter (1a) at an incident angle of 0, the optical filter (1a) satisfies given requirements. When light with a wavelength of 300 to 1200 nm is incident on the optical filter (1a) at incident angles of 0, 30, 35, and 40, the optical filter (1a) satisfies given requirements related to a normalized spectral transmittance. The normalized spectral transmittance is determined by normalization of a spectral transmittance for each incident angle so that the maximum of the spectral transmittance for each incident angle in the wavelength range of 400 to 650 nm is 100%.
