摘要:
A light emitting device including a second conductive type semiconductor layer; an active layer over the second conductive type semiconductor layer; a first conductive type semiconductor layer over the active layer; a second electrode in a first region under the second conductive type semiconductor layer; a current blocking layer including a metal; and a first electrode over the first conductive type semiconductor layer. Further, the first electrode has at least one portion that vertically overlaps the current blocking layer.
