Claim:
1. A light emitting device comprising: a conductive substrate; a second electrode layer on the conductive substrate and including a center portion and a peripheral portion surrounding the center portion; a protective layer on the peripheral portion of the second electrode layer; a light emitting structure including a second conductive type semiconductor layer on the second electrode layer, an active layer on the second conductive type semiconductor layer and a first conductive type semiconductor layer on the active layer; and a first electrode layer on the first conductive type semiconductor layer, wherein the second conductive type semiconductor layer includes first edge portions in contact with a bottom surface of the active layer, and second edge portions extended to opposite outsides of the first edge portions, wherein a material of the protective layer is different from that of the second electrode layer, and wherein one of outer side-surfaces of the second edge portions is vertically aligned with one of outer side-surfaces of the protective layer.
