Abstract
An optical film includes a substrate film and an adhesion-facilitating layer arranged on at least one surface of the substrate film, in which the adhesion-facilitating layer contains a resin, silica particles, and metal oxide particles other than the silica particles; a ratio of a percentage A of an area derived from the metal oxide particles in a total area of a specific lower region to a percentage B of an area derived from the metal oxide particles in a total area of a specific upper region is 1.05 or more; and the surface of the adhesion-facilitating layer opposite to the substrate film side has an arithmetic mean roughness Ra of 10 nm or more and less than 20 nm.
