摘要：
An optical film is provided and includes: a transparent support; and a light diffusion layer containing light-transmitting particles and a binder. The light diffusion layer has an average thickness of from 7.5 to 30 μm, and the average thickness of the light diffusion layer is from 1.4 to 3.5 times as large as an average particle diameter of the light-transmitting particles.
