Light emitting device and method of fabricating the same

A light emitting device, comprising:

• a substrate;
• light emitting cells disposed on the substrate, each light emitting cell comprising a first semiconductor layer, an active layer, and a second semiconductor layer;
• a first connection metal disposed between the substrate and the light emitting cells, the first connection metal electrically connecting the light emitting cells;
• a second connection metal disposed between the first semiconductor layers and the first connection metal, the second connection metal being electrically connected to the first semiconductor layer;
• a first electrode pad spaced apart from light emission surfaces of the light emitting cells and disposed on a first surface of the light emitting device opposite to the substrate, wherein the first electrode pad is electrically connected to the first semiconductor layer through the second connection metal;
• a second electrode pad spaced apart from light emission surfaces of the light emitting cells, wherein the second electrode pad is electrically connected to the second semiconductor layer;
• and
• a first insulating layer disposed between the first connection metal and the second connection metal.
