Abstract
Disclosed is a light emitting device. The light emitting device includes a light emitting structure layer including a first semiconductor layer, an active layer, and a second semiconductor layer, an electrode electrically connected to the first semiconductor layer, an electrode layer under the light emitting structure layer, and a conductive support member under the electrode layer. A channel layer is between the second semiconductor layer and the electrode layer. A protrusion projected from at least one of edges of the conductive support member includes and having a rough surface.
