Abstract:
1. A light emitting device comprising: a conductive support layer; a light emitting structure layer on the conductive support layer, wherein the light emitting structure layer comprises a first semiconductor layer, an active layer on the first semiconductor layer, and a second semiconductor layer on the active layer; a first transparent conductive layer and a second transparent conductive layer disposed between the conductive support layer and the light emitting structure layer, wherein the first transparent conductive layer is disposed around the second transparent conductive layer, and wherein a first portion of the second transparent conductive layer is disposed under the first transparent conductive layer, and wherein a second portion of the second transparent conductive layer is disposed between the first semiconductor layer and the conductive support layer; a reflective layer between the conductive support layer and the first and second transparent conductive layers; and an electrode on the light emitting structure, wherein at least a portion of the electrode overlaps the second transparent conductive layer, wherein at least portion of the second transparent conductive layer contacts the first semiconductive layer at a central portion of the first semiconductive layer, and at least portion of the first transparent conductive layer contacts the first semiconductive layer at a peripheral portion of the first semiconductive layer, and wherein the reflective layer contacts the second transparent conductive layer and a peripheral portion of the first transparent conductive layer.
