Abstract
A backlight unit includes a light conversion member; a light guide plate including a light exit surface, a rear surface facing the light exiting surface, and connection surfaces including a first surface and a second surface facing each other to connect the light exit surface and the rear surface; a reflective member; and a light source emitting a first color light incident to the first surface and a portion of the first color light reaches the second surface on which the reflective member is disposed to specularly reflect the portion of the first color light. The light conversion member is disposed on the light exit surface, receives the first color light from the light guide plate, and emits a second color light different from the first color light.
