Abstract
Disclosed is a light-emitting device including a conductive support substrate, a reflective layer arranged on the conductive support substrate, a first electrode layer arranged on the reflective layer and provided with a step in at least one region of the edge thereof, a protective layer arranged on the step, and a light-emitting structure arranged on the first electrode layer and the protective layer, the light-emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer interposed between the first conductive semiconductor layer and the second conductive semiconductor layer, wherein at least one region of the reflective layer and the first electrode layer vertically overlaps the protective layer. Based on this configuration, the light-emitting device can exhibit improved adhesion between the electrode layer and the reflective layer and be provided with a wider reflective layer, thus improving brightness.
