Patent ID: 8901582

Claim:
A light-emitting device comprising: a first light-emitting structure comprising a first conductive type semiconductor layer, a first active layer on the first conductive type semiconductor layer, and a second conductive type semiconductor layer on the first active layer; a second light-emitting structure on a top surface of the first light-emitting structure, the second light-emitting structure comprising a third conductive type semiconductor layer, a second active layer on the third conductive type semiconductor layer, and a fourth conductive type semiconductor layer on the second active layer; an insulation layer inter-disposed between a top surface of the first light-emitting structure and a bottom surface of the second light-emitting structure; and a first electrode contacted with the second conductive type semiconductor layer and the third conductive type semiconductor layer, wherein the first electrode contacts the insulation layer, wherein the first electrode has a thickness thicker than that of the insulating layer.
