Patent ID: 8669582

Claim:
A light emitting device comprising: a light transmissive substrate; a light emitting structure disposed on the light transmissive substrate, comprising a first conductive type semiconductor layer, an active layer and a second conductive type semiconductor layer; a conductive layer disposed on the second conductive type semiconductor layer; a first electrode part disposed on the conductive layer, wherein the first electrode part comprises a first pad part, a first expanded part being expanded from the first pad part, and a plurality of first contact electrodes connected to the first expanded part, wherein the first electrode part is in contact with the first conductive type semiconductor layer, and wherein the plurality of first contact electrodes pass through the conductive layer, the second conductive type semiconductor layer and the active layer and the plurality of the first contact electrodes are spaced apart from each other; and a first insulation layer disposed between the conductive layer and the first electrode part, between the second conductive type semiconductor layer and the first electrode part and between the active layer and the first electrode part, wherein the distances between two neighboring ones of the first contact electrodes are increasing as they are getting more distant from the first pad part.
