Patent ID: 8076688

Claim:
A light emitting diode, comprising: a lower semiconductor layer arranged on a substrate; an upper semiconductor layer arranged above the lower semiconductor layer such that edge regions of the lower semiconductor layer are exposed, the upper semiconductor layer comprising indents that are parallel with diagonal directions from positions in the edge regions adjacent to corners of the substrate, the indents exposing the lower semiconductor layer and comprising distal ends spaced apart from each other; an active layer disposed between the lower semiconductor layer and the upper semiconductor layer; a lower electrode arranged on a first edge region of the edge regions of the lower semiconductor layer, the lower electrode corresponding to a first corner of the corners of the substrate; a transparent electrode layer arranged on the upper semiconductor layer; an upper electrode arranged on the transparent electrode layer, the upper electrode corresponding to a second corner of the corners of the substrate; lower extensions extending from the lower electrode and arranged on a second edge region of the edge regions of the lower semiconductor layer and arranged on regions of the lower semiconductor layer exposed through the indents; and an upper extension arranged on the transparent electrode layer and extending from the upper electrode.
