Abstract
Provided is an anti-glare film having excellent anti-glare property, and suppressing white muddiness and scintillation, generation of cracks when attaching the films to polarizing elements and a fabrication process of liquid crystal cells, and changes of an anti-glare property over time. An anti-glare film comprises a light-transmitting substrate; and a diffusion layer having a surface roughness and provided on at least one surface of the light-transmitting substrate, in which the diffusion layer is obtainable by applying, on the at least one surface of the light-transmitting substrate, a coating composition including organic fine particles and a radiation curable binder that includes a (meth)acrylate monomer as an essential component, drying the composition to form a coating, and curing it, the organic fine particles in the diffusion layer have an impregnation layer being impregnated with the radiation curable binder, and the impregnation layer has an average thickness of 0.01 to 1.0 μm.
