Abstract:
1. A light emitting device comprising: a support substrate; a conductive layer on the support substrate; a light emitting structure including a first nitride based semiconductor layer, an active layer and a second nitride based semiconductor layer; a first electrode on the light emitting structure; and a channel layer disposed under the conductive layer and at an adjacent region of the conductive layer, wherein a central portion of the first electrode is vertically non-overlapped with the conductive layer, wherein the conductive layer is composed of a first layer and a second layer on the first layer, wherein the second layer is in direct contact with the light emitting structure, wherein the channel layer includes a recess, wherein both ends of the recess directly contacts with the light emitting structure, and wherein all areas of the conductive layer is placed in the recess.
