Abstract

Disclosed is an anti-glare film comprising a resin base film (101a, 101b) and a hard coat layer (102a, 102b) arranged on the surface of the resin base film (101a, 101b) and having a surface with a fine recessed and projected structure. The resin base film (101a, 101b) has a multilayer structure including at least one transparent resin layer (103a, 103b) composed of a transparent resin, and at least one light diffusion layer (104a, 104b) containing a transparent binder resin and a fine particle (105a, 105b) having a refractive index different from that of the transparent binder resin. Also disclosed are an anti-glare polarizing plate using such an anti-glare film, and an image display device. The resin base film (101a, 101b) has an internal haze value of not less than 5% but not more than 30%, and the hard coat layer (102a, 102b) has a surface haze value of not less than 0.5% but not more than 15% and an internal haze value of not more than 2%.
