Abstract:
1. A light-emitting device comprising: a conductive support substrate; a reflective layer on the conductive support substrate; a first electrode layer on the reflective layer and provided with a first step in at least one region of an edge of the first electrode layer; a protective layer on the first step, wherein the protective layer includes at least a first layer and a second layer arranged on the first layer, wherein the first layer contains silicon dioxide (SiO a light-emitting structure 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; and an insulating layer arranged at a side of the light-emitting structure, wherein at least one first region of the reflective layer vertically overlaps the second layer of the protective layer, and the first step of the first electrode layer vertically overlaps the second layer of the protective layer such that the first step of the first electrode layer is between the at least one first region of the reflective layer and the second layer of the protective layer, wherein a width of the second layer of the protective layer is greater than a width of the first step, the conductive support substrate has a wider area than the first electrode layer, and a lower side of the light-emitting structure is disposed on an upper side of the protective layer, wherein the insulating layer extends from a top of the protective layer along the side of the light-emitting structure to a partial top of the first semiconductor layer, and wherein the insulating layer contacts an upper side of the protective layer.
