摘要:
The present invention provides an antiglare film having an excellent antiglare property and being capable of suitably preventing an occurrence of scintillation and a decrease in contrast. The film includes a light-transmitting substrate and a diffusion layer. The diffusion layer has a surface roughness and is formed on at least one side of the light-transmitting substrate, wherein the diffusion layer contains organic fine particles (A), organic fine particles (B), and a cured product of a binder component, and satisfies the expressions: (1) rA>rB; (2) ΔA CB/CA, where CA and CB represent a content ratio of the organic fine particles (A) or the organic fine particles (B) in the diffusion layer, respectively, rA and rB represent an average particle size thereof, respectively, and ΔA and ΔB represent a refractive index thereof relative to the cured product of the binder component, respectively.
