Abstract:
The present invention aims to provide an antiglare film that can be thinned without lowering the hard coat properties and antiglare properties, highly suppress scintillation and white muddiness, and provide display images with a high contrast. The antiglare film includes a light-transmitting substrate and an antiglare layer with surface roughness on one face of the light-transmitting substrate, wherein the antiglare layer contains silica fine particles, organic fine particles, and a binder resin, part of the silica fine particles form agglomerates and the agglomerates are contained in the antiglare layer sparsely and densely, the agglomerates of the silica fine particles are densely distributed around the organic fine particles, and part of the agglomerates densely distributed around the organic fine particles are attached to the surface of the organic fine particles and/or have some of the silica fine particles contained in the agglomerates impregnate the inside of the organic fine particles.
