Abstract:
1. A nitride light emitting device, comprising: a light emitting structure including a first conduction type cladding layer, an active layer, and a second conduction type cladding layer; a transparent electrode on the second conduction type cladding layer; and an electrode on the transparent electrode, wherein the second conduction type cladding layer has a pattern including at least one recess portion and at least one protrusion portion, wherein a lower side of the at least one recess portion is closer to the active layer than to a bottom side of the electrode, wherein the transparent electrode comprises a second pattern corresponding to the pattern of the second conduction type cladding layer, wherein the transparent electrode comprises a substantially flat top surface, wherein the transparent electrode is directly disposed on the at least one recess portion of the second conduction type cladding layer, wherein the substantially flat top surface of the transparent electrode is higher than a top surface of the pattern of the second conduction type cladding layer, and wherein the second conduction type cladding layer has a thickness of less than 150 nm.
