Abstract:
1. A light emitting device comprising: a conductive substrate; a first conductive layer formed on the conductive substrate; a second conductive layer formed on the first conductive layer; a second semiconductor layer formed on the second conductive layer; an active layer formed on the second semiconductor layer; a first semiconductor layer formed on the active layer; and an insulation layer, wherein the first conductive layer includes at least one via which penetrates the second conductive layer, the second semiconductor layer and the active layer and projects into a certain area of the first semiconductor layer, and then is electrically connected to the first semiconductor layer, wherein the insulation layer is formed between the first conductive layer and the second conductive layer and on the side wall of the via, wherein the first semiconductor layer includes a charge distribution layer therein, and wherein the charge distribution layer has a charge concentration lower than that of the first semiconductor layer.
