Abstract: A light emitting device is a micro-scale light emitting device including a semiconductor stack, an insulation layer, and a metal reflection layer. The semiconductor stack includes a first conductivity type semiconductor layer, a second conductivity type semiconductor layer, and an active layer disposed between the first conductivity type semiconductor layer and the second conductivity type semiconductor layer. The insulation layer covers upper and side surfaces of the semiconductor stack. The metal reflection layer is disposed on the insulation layer, and covers at least a portion of the side surface of the semiconductor stack. The insulation layer includes a distributed Bragg reflector.

Abstract: A unit pixel includes a transparent substrate having an upper surface and a lower surface, a plurality of light emitting devices arranged over the upper surface of the transparent substrate, and a reflector disposed between the light emitting devices and the transparent substrate. Light emitted from the light emitting devices is configured to exit to the outside through the upper and lower surfaces of the transparent substrate, and the reflector is configured to reflect light proceeding to the upper surface of the transparent substrate from the inside of the transparent substrate.

Abstract: A unit pixel includes a transparent substrate, a plurality of light emitting devices arranged on the transparent substrate, and an optical layer disposed between the light emitting devices and the transparent substrate and transmitting light emitted from the light emitting devices. The transparent substrate has a concavo-convex pattern on a surface facing the light emitting devices.
