Abstract:
1. A backlight unit, comprising: an arrangement surface on which a plurality of light sources is arranged; and a plurality of inclination walls disposed to surround the arrangement surface to form an irradiation area and inclined toward an outside of the arrangement surface at an angle larger than 90 degrees with respect to the arrangement surface, the inclination walls defining a reflection surface configured to reflect light emitted from the light sources, the inclination walls including a first inclination wall having a first inclination angle and a second inclination wall having a second inclination angle larger than the first inclination angle with respect to the arrangement surface, wherein the irradiation area is configured to be irradiated with the light emitted from the light sources and light reflected from the reflection surface, the light sources include a first light source arranged close to the first inclination wall and a second light source arranged close to the second inclination wall, and a distance between the first inclination wall and the first light source is shorter than a distance between the second inclination wall and the second light source in a plan view of the irradiation area.
