Patent ID: 8878212

Claim:
A light emitting device comprising: a substrate; at least one first electrode disposed through the substrate; a first contact layer disposed on a top surface of the substrate and being electrically connected to the first electrode; a second contact layer disposed on a bottom surface of the substrate and being electrically connected to the first electrode; a light emitting structure layer disposed above the substrate spaced apart from the substrate and being electrically connected to the first contact layer; a transparent conductive layer disposed between the substrate and the light emitting structure layer; and a second electrode layer on a top surface of the light emitting structure layer, wherein the light emitting structure layer includes a first conductive semiconductor layer under the second electrode 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, wherein the transparent conductive layer directly contacts the first contact layer, wherein the transparent conductive layer is electrically connected to the first contact layer and the second conductive semiconductor layer, and wherein the first contact layer is located at a higher position than the top surface of the substrate.
