Abstract: A directional backlight unit is provided, including a light guide plate, a light source, and a grating that is formed on a light-emitting surface of the light guide plate. The grating is configured such that an intensity of one ray of light, of the light irradiated by the light source and diffracted and emitted by the grating, is greater than a sum of intensities of all other rays of light, of the light irradiated by the light source and diffracted and emitted by the grating.
