Abstract:
1. A semiconductor light emitting device having a reflective layer comprising: a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer under the first conductive semiconductor layer, and an active layer between the first conductive semiconductor layer and the second conductive semiconductor layer; an electrode on a first region of the first conductive semiconductor layer; a conductive support member under the light emitting structure; a metal layer between the light emitting structure and the conductive support member; wherein a bottom part of the metal layer is formed in the conductive support member and the reflective layer between the metal layer and the light emitting structure, wherein the metal layer is physically contacted with a lower surface of the reflective layer, wherein the reflective layer includes a first layer and a second layer, wherein the first layer has a different material from the second layer, wherein the metal layer has a protrusion on the conductive support member, wherein the first conductive semiconductor layer includes a roughness formed on an upper surface of the first conductive semiconductor layer, and wherein the first region is formed with a flat surface.
