Abstract
The invention provides a group III-nitride light emitting device having improved external quantum efficiency and brightness. The light emitting device comprises an n-type clad layer, an active layer and a p-type clad layer formed in their order. Also, a p-electrode is formed on the p-type clad layer, wherein the p-electrode comprises CuInOlayer, a transparent conductive oxide layer and a reflective metal layer sequentially formed on the p-type clad layer. The reflective metal layer may be an Ag layer or an Al layer.
