Abstract: An optical film, a polarizing plate, a liquid crystal panel, and an image display apparatus are provided, wherein interference fringes can be made to be invisible, and cloudiness can be reduced. In accordance with one aspect of the present invention, an optical film is provided, including a light transmissive substrate, and a functional layer disposed on the light transmissive substrate, wherein the functional layer has a concavo-convex surface forming a surface of the optical film. Assuming that a slope angle of the concavo-convex surface with respect to a film plane of the optical film in a cross section along a direction normal to the film plane is a surface angle, a percentage of a region in which the surface angle is 0.05° or more is 50 % or more in the concavo-convex surface, and the root mean square slope RΔq of a roughness curve on the concavo-convex surface is 0.003 or less.
