Abstract

A display device includes a light source, a liquid crystal panel including a first sub-pixel and a second sub-pixel adjacent to the first sub-pixel in a first direction, and an optical control element including a light shielding layer. Each of the first sub-pixel and the second sub-pixel has a first width in the first direction. The light shielding layer includes an opening portion having a second width in the first direction. The second width is 1.5 times the first width. In all of light rays irradiated from the light source and transmitting through the opening portion, an angle between a first light ray transmitting through the first sub-pixel and emitted to an outside and the second light ray transmitting through the second sub-pixel and emitted to the outside is less than or equal to 2 degrees.
