Abstract
An optical film includes a base member and an optical layer provided on the base member. The optical layer has an irregular shape on a surface thereof, and 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 regions and sparsely in other regions 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 fine particles are organic fine particles having an average particle diameter of 2 μm or more and 8 μm or less, a ratio ((D/T)×100) of the average particle diameter D of the fine particles to an average film thickness T of the optical layer is 20% or more and 70% or less, and a transmitted image clarity value measured with an optical comb having a width of 0.125 mm is 45 or more.
