Abstract
An optical film includes, in the following order, a support; an antiglare layer having an uneven surface; a high refractive index layer; and a low refractive index layer, wherein an arithmetic average roughness (Ra) of the optical film is: 0.03 μm<Ra<0.4 μm, an average distance of unevenness (Sm) of the optical film is: 80 μm<Sm<700 μm, a region of 0°<θ<0.5° (θ(0.5)) of the optical film, where θ is a tilting angle of the unevenness, accounts for 40% or more, and an integral reflectance of the optical film is 1.5% or less.
