OPTICAL FILM, ANTIREFLECTION FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical film being free from surface errors and having a high film strength and stably exhibiting necessary optical characteristics, a polarizing plate and an image display device using the optical film.

SOLUTION: 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.
