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.
