| titleOfInvention | Light emitting device and lighting system having the same |
| abstract | A light emitting device according to an embodiment includes a substrate, a first conductivity type semiconductor layer disposed on the substrate, an active layer disposed on the first conductivity type semiconductor layer, and a second conductivity type semiconductor layer disposed on the active layer and a first undoped first hole injection layer disposed between the active layer and the second conductivity type semiconductor layer, and a second hole injection layer disposed on the first hole injection layer and doped with a p-type dopant. layers may be included. In the embodiment, by forming a layer from which the p-type dopant is removed in the hole injection layer, the output voltage and the light efficiency measurement voltage can be improved while the operating voltage is maintained. |
