Abstract

An antiglare film includes a base member and an optical layer provided on the base member, and the optical layer has an irregular shape on a surface thereof. The irregular shape is obtained by applying a coating material containing fine particles and a resin onto the base member, distributing the fine particles densely in some portions and sparsely in other portions by convection that occurs in the coating material, and curing the coating material. The resin contains 3% by weight or more and 20% by weight or less of a polymer, the average particle diameter of the fine particles is 2 μm or more and 8 μm or less, and the average film thickness of the optical layer is 8 μm or more and 18 μm or less.
