Abstract:
1. A light emitting diode includes: a conductive support substrate; a second electrode layer on the conductive support substrate and including a center portion and a peripheral portion surrounding the center portion; a protective layer on the peripheral portion of the electrode layer; a light emitting structure including a second conductive semiconductor layer on the second electrode layer, an active layer on the second conductive semiconductor layer and a first conductive semiconductor layer on the active layer; and a first electrode layer on the first conductive semiconductor layer, wherein the center portion has a thickness different from that of the peripheral portion, wherein the protection layer is directly in contact with the second conductive semiconductor layer, and wherein the second conductive semiconductor layer includes edge portions extending outside of the light emitting structure, the edge portions are exposed upward and aligned with respective edges of the protective layer.
