Abstract: According to one embodiment, a display device includes a light source unit, a light guide unit, a lens, and a light emitting layer. The light source unit emits light to the light guide unit. The lens concentrates the light emitted from the light source unit. The light guide unit guides the light concentrated by the lens toward the light emitting layer. The light guided by the light guide unit is transmitted to the light emission layer without any intervening prism layer.
