Abstract
An antiglare film and an antiglare sheet with which an image display apparatus excelling in contrast while maintaining excellent antiglare performance is obtained, and a simple process for producing them are provided. In the antiglare film of the present invention, a rugged shape in a first direction is substantially different from a rugged shape in a second direction perpendicular to the first direction. Preferably, an average gradient angle θaof the rugged shape in the first direction is larger than an average gradient angle θaof the rugged shape in the second direction. More preferably, a difference Δθa=θa−θabetween the average gradient angle θaand the average gradient angle θais 0.5° to 30°.
