Anti-glare film, method for producing anti-glare film, polarizer and image display device

摘要

An antiglare film that includes 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 a cured product of a binder component and organic fine particles (A) dispersed in the cured product of the binder component, and the following expression is satisfied: |NA−nb|>|nA−nb|>0 where NA represents a refractive index of the organic fine particles (A) before the organic fine particles (A) are introduced into the diffusion layer, nA represents a refractive index of the organic fine particles (A) in the diffusion layer, and nb represents a refractive index in the cured product of the binder component.
