Patent ID: 8395182

Claim:
A light emitting device comprising: a substrate; a protective layer on the substrate; an electrode layer on the protective layer; a light emitting structure disposed on the electrode layer to generate light and provided with a first semiconductor layer, an active layer under the first semiconductor layer, and a second conductive semiconductor layer under the active layer, wherein the electrode layer comprises a first layer disposed on a top surface of the protective layer and a second layer disposed on the first layer to reflect the light emitted from the light emitting structure; a first electrode having a first end disposed on a top surface of the light emitting structure and a second end disposed on the protective layer, wherein the protective layer comes into Schottky contact with at least one of the electrode layer and the first electrode; a protective member provided at a lateral side of the light emitting structure, wherein a portion of the protective member is disposed between the light emitting structure and the first electrode; and at least one of a diffusion barrier layer and an adhesive reinforcing layer between the first and second layers.
