Abstract:
Provided is an antiglare film having a hard coat property, capable of highly suppressing generation of a rainbow interference pattern and interference fringes in display images, preventing white muddiness and scintillation of a display screen, while giving high contrast in a bright room and a dark room. The antiglare film includes an antiglare layer having an uneven form on its surface and formed on one face of a transparent substrate having an in-plane birefringence and a retardation of 3000 nm or higher. The antiglare layer contains silica fine particles, organic fine particles, and a binder resin. The silica particles include particles forming agglomerates to be contained coarsely and densely in the antiglare layer. The agglomerates are distributed densely around the organic fine particles, and some agglomerates adhere to surfaces of the organic particles and/or some silica particles are impregnated in the inside of the organic particles.
