Abstract:
1. A light emitting device comprising: a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer under a bottom surface of the first conductive semiconductor layer, and an active layer between the bottom surface of the first conductive semiconductor layer and a top surface of the second conductive semiconductor layer; an insulating layer disposed on a lateral surface of the light emitting structure; an electrode on the first conductive semiconductor layer; an electrode layer under a bottom surface of the second conductive semiconductor layer; a conductive support member under the electrode layer; and a protective layer including a first portion between the light emitting structure and the electrode layer and a second portion extending outward beyond a bottom surface of the light emitting structure, wherein the first conductive semiconductor layer includes a first top surface and a second top surface located at lower position than that of the first top surface, wherein the second top surface of the first conductive semiconductor layer is closer to an edge region of the first conductive semiconductor layer than a center region of the first conductive semiconductor layer, wherein the second top surface of the first conductive semiconductor layer is vertically overlapped with the first portion of the protective layer in a vertical direction, wherein an entire region of the protective layer is located at a lower position than that of the bottom surface of the second conductive semiconductor layer.
