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.
