Patent ID: 7482639

Claim:
A nitride-based light-emitting device comprising an active layer between an n-type clad layer and a p-type clad layer, wherein an ohmic contact layer made of a transparent conductive oxide is formed on the p-type clad layer, and the transparent conductive oxide is one selected from the group consisting of a first transparent conductive oxide comprising gallium, indium, and oxygen as main components, a second transparent conductive oxide comprising zinc, indium, and oxygen as main components, a third transparent conductive oxide comprising gallium, indium, tin, and oxygen as main components, and a fourth transparent conductive oxide comprising zinc, indium, tin, and oxygen as main components, and further comprising a reflective layer made of at least one selected from the group consisting of Ag, Al, Zn, Mg, Ru, Rh, and Cr, on the ohmic contact layer.
