Patent ID: 8866173

Claim:
A light emitting device, comprising: a light emitting structure including a first semiconductor layer, an active layer, and a second semiconductor layer; an electrode on the light emitting structure; a protection layer under a peripheral region of the light emitting structure; and an electrode layer under the light emitting structure, wherein the protection layer comprises a first layer, a second layer, and a third layer, wherein the first layer comprises a first metallic material, wherein the second layer is disposed between the first layer and the third layer, the second layer has an insulating material or an oxide-based conductive material, wherein a portion of the electrode layer directly physically contacts the light emitting structure, wherein a top most surface of the protection layer is disposed below the light emitting structure wherein the electrode layer comprises one of a conductive support member, an adhesive layer, a reflective layer, and an ohmic contact layer, and wherein the first, the third, and the second layers directly physically contact the ohmic contact layer.
