Abstract
A backlight unit includes one or more light sources operable to emit light and a light guide plate arranged adjacent to the one or more light sources, reflected lights exiting the one or more light sources via the second surfaces and entering the light guide plate. A light source includes a light emitting device having a substrate and a semiconductor stack disposed on the substrate. The reflector is structured and positioned to block light emitted from a first surface of the light emitting device by reflecting the light emitted from the first surface toward second surfaces of the light source.
