Abstract
A light emitting device includes a substrate, at least one electrode, a first contact layer, a second contact layer, a light emitting structure layer, and an electrode layer. The electrode is disposed through the substrate. The first contact layer is disposed on a top surface of the substrate and electrically connected to the electrode. The second contact layer is disposed on a bottom surface of the substrate and electrically connected to the electrode. The light emitting structure layer is disposed above the substrate at a distance from the substrate and electrically connected to the first contact layer. The light emitting structure layer includes a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer. The electrode layer is disposed on the light emitting structure layer.
