Abstract
A light control film includes a light shielding layer and a light diffusion portion, and, when an area of a part where the light shielding layer is in contact with one surface of the base material is set to S1, and an area of a part where a low refractive index portion is exposed between light incidence end surfaces is set to S2, the light shielding layer and the light diffusion portion are formed so as to satisfy (S1−S2)/S1×100≥50.
