Abstract:
A light control film (light control member) includes a light transmissive base, a plurality of light shielding portions scattered over one surface of the base, and a light diffusing portion formed on the one surface of the base in a region other than regions in which the light shielding portions are formed. The light diffusing portion has a light exit end face and a light incident end face having a larger area than the light exit end face, and the height of the light diffusing portion is greater than the thickness of the light shielding portions. At least part of the opening of at least some of a plurality of air-cavities has a protrusion which is formed of a portion of the light diffusing portion that projects toward the inner side of the opening.
