Beschreibung
Zusammenfassung:	An optical film including a first film substrate, and a light diffusion layer that is formed on the first film substrate, wherein the light diffusion layer contains a binder resin and light-diffusing particles, of the light-diffusing particles, 10% or more by number of the light-diffusing particles form an uneven structure on a surface of the light-diffusing layer by the 10% or more of the light-diffusing particles protruding more than a surrounding area not containing any light-diffusing particles, and of the light diffusing particles which cause the binder resin to be protruded and have a protruded portion, 90% or more by number of the protruded portion of light-diffusing particles is covered by the binder resin.
