Abstract: A backlight unit includes: a light source which generates light; a light guide plate which receives the light from the light source and guides the light to a display panel which displays an image with the light, the light guide plate including a light incident side surface to which the light from the light source is incident, and an opposing side surface which opposes said light incident side surface; and a reflection member disposed facing the opposing side surface of the light guide plate. Along a length of the opposing side surface of the light guide plate, the reflection member facing the opposing side surface includes at least two reflective portions having different reflectances from each other.

Abstract: A display device includes: a display panel curved in a first direction; a light source which emits a light; and a light guide plate which guides the light from the light source toward the display panel. The light guide plate includes an exit surface curved in the first direction corresponding to a shape of the display panel and an incidence surface, which is defined by a side surface of the light guide plate in the first direction, where the light from the light source is incident onto the incidence surface. The incidence surface is substantially parallel to a normal line at a central portion of the exit surface.
