Claim Text:
1. A light emitting device comprising: a plurality of light emitting cells including a first light emitting cell and a second light emitting cell spaced apart from each other, each of the first light emitting cell and the second light emitting cell including a first semiconductor layer, a second semiconductor layer under the first semiconductor layer, and an active layer between the first semiconductor layer and the second semiconductor layer; a conductive support member under the first light emitting cell and light emitting cell second light emitting cell; a first conductive layer between the first light emitting cell and the conductive support member; a second conductive layer between the first conductive layer and the conductive support member; a third conductive layer between the second light emitting cell and the conductive support member; a fourth conductive layer between the third conductive layer and the conductive support member; a first insulating layer between the second conductive layer and the fourth conductive layer, between the second conductive layer and the conductive support member, and between the fourth conductive layer and the conductive support member; a first hole disposed in the active layer and the second semiconductor layer of the first light emitting cell; a second hole disposed in the active layer and the second semiconductor layer of the second light emitting cell; and a second insulating layer disposed in the first hole and the second hole, wherein the second conductive layer includes a first portion disposed in the first hole and is electrically connected to the first semiconductor layer of the first light emitting cell by the first portion and the third conductive layer.
