Abstract:
1. A light emitting device, comprising: a light emitting semiconductor layer comprising a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer; an electrode layer on the first conductive semiconductor layer; a first passivation layer on the light emitting semiconductor layer; and a second passivation layer on the first passivation layer, wherein the first passivation layer comprises an inorganic material, wherein the second passivation layer comprises an organic material, wherein the first conductive semiconductor layer has a top surface that has a downwardly-recessed groove, a plurality of protrusions being disposed on a bottom surface of the groove, wherein the electrode layer is disposed on a bottom surface of the groove, and wherein the electrode layer substantially has the same top surface as that of the top surface of the first conductive semiconductor layer.
