Abstract:
1. A light emitting device comprising: a conductive support layer; a light emitting structure layer disposed on the conductive support layer, wherein the light emitting structure layer comprises a first semiconductor layer, an active layer disposed on the first semiconductor layer, and a second semiconductor layer disposed on the active layer; a transparent conductive layer disposed between the conductive support layer and the light emitting structure layer, wherein the first transparent conductive layer comprises a first transparent conductive layer and a second transparent conductive layer; and a reflective layer disposed between the conductive support layer and the transparent conductive layer; and an electrode on a top surface of the light emitting structure layer, wherein the first transparent conductive layer is disposed around the second transparent conductive layer, wherein the first transparent conductive layer includes a first portion disposed under a lower surface of the first semiconductor layer and a second portion extended outwardly from the lower surface of the light emitting structure layer, wherein the first transparent conductive layer and the second transparent conductive layer comprise different materials, wherein the reflective layer includes a protrusion protruding toward a lower surface of the second transparent conductive layer.
