Abstract:
1. A light emitting device comprising: a stressed reflective metal support comprising at least two pairs of first and second reflective metal layers; a light emitting structure layer comprising a first conductive type semiconductor layer, a second conductive type semiconductor layer, and an active layer between the first conductive type semiconductor and the second conductive type semiconductor layer on the stressed reflective metal support; a current block region between the stressed reflective metal support and the light emitting structure layer; an electrode on the light emitting structure layer, wherein at least one portion of the current blocking region is overlapped with the electrode with respect to the light emitting structure layer, wherein the stressed reflective metal support includes at least one of Al, Ag, an APC(Ag—Pd—Cu) alloy, and an Au—Ni alloy, and wherein an upper surface of the stressed reflective metal support is contacted with the current block region and the bottom surface of the light emitting structure layer.
