Abstract
The present invention provides an antiglare film having an excellent antiglare property and being capable of suitably preventing the occurrence of scintillation and a decrease in contrast.
The present invention provides an antiglare film including a light-transmitting substrate and a diffusion layer, the diffusion layer having a surface roughness on a surface thereof and being 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 following expressions (1), (2), and (3):
ΔA<ΔB expression (1),
RA>RB expression (2), and
CA/RA3<CB/RB3 expression (3),
where CA represents a content of the organic fine particles (A) in the diffusion layer, RA represents an average particle size thereof, and ΔA represents a refractive index thereof with respect to the cured product of the binder component; and CB represents a content of the organic fine particles (B) in the diffusion layer, RB represents an average particle size thereof, and ΔB represents a refractive index difference thereof with respect to the cured product of the binder component.
