Abstract
Disclosed is a light-emitting device. The light-emitting device comprises: a light-emitting structure comprising a first conductive semiconductor layer, a second conductive semiconductor layer, and an active layer disposed between the first conductive semiconductor layer and the second conductive semiconductor layer; a first contact electrode which ohmically contacts the first conductive semiconductor layer; a second contact electrode which is disposed on the second conductive semiconductor layer; and an insulation layer which is disposed on the light-emitting structure and insulates the first contact electrode and the second contact electrode, wherein the light-emitting structure has a non-polar or semi-polar growth surface; the upper surface of the second conductive semiconductor layer comprises a non-polar or semi-polar surface; and the second contact electrode comprises a conductive oxide layer which ohmically contacts the second conductive semiconductor layer, and a reflective electrode layer disposed on the conductive oxide layer.
