An object of the present invention is to provide an optical film which is excellent in the adhesiveness between a polymer support and a photo alignment film and in which a liquid crystal compound having reverse wavelength dispersibility is uniformly aligned. The optical film is obtained by laminating, in the following order: a polymer support containing an additive; a photo alignment film; and an optically anisotropic film, wherein the optically anisotropic film is formed of a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound having reverse wavelength dispersibility, and an amount of a component derived from the additive of the polymer support, which is contained in a boundary region with the optically anisotropic film in the photo alignment film is 0.10 to 0.50 mass % with respect to a total mass of the photo alignment film.
