Abstract:
The light control film includes a base material with transparency and a light control layer that is provided on a side of a surface which faces a display surface of a display panel in the base material, has a light shielding portion which is formed on one surface of the base material, and controls an emission direction of light by diffusing light which is emitted from the display surface, in which the light control layer includes a light emission end surface that contacts with the base material, a light incident end surface that faces the light emission end surface and has a larger area than an area of the light emission end surface, and a reflection surface that contacts with the light emission end surface and the light incident end surface and reflects light which is incident from the light incident end surface, a height from the light incident end surface to the light emission end surface is larger than a layer thickness of the light shielding portion, and the reflection surface reflects light to allocate light at a polar angle with a relatively high light flux amount among directions along prescribed azimuth angles in the display surface to light at a polar angle with relatively low luminance among directions along prescribed azimuth angles.
