Patent ID: 8581277

Claim:
A light emitting device comprising: a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer under the first conductive semiconductor layer, and an active layer between the first conductive semiconductor layer and 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 the second conductive semiconductor 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 lower surface of the light emitting structure, wherein the first conductive semiconductor layer includes a first top surface including a roughness on a first region, and a second top surface lower than the first region and being closer the lateral surface of the light emitting structure than the first region, wherein the second top surface of the first conductive semiconductor layer is disposed on an edge portion of the first top surface of the first conductive semiconductor layer.
