| titleOfInvention | Light emitting device, light emitting device manufacturing method and lighting system having the same |
| abstract | A light emitting device according to an embodiment includes a substrate having a pattern portion disposed on its upper surface, a first buffer layer disposed on the substrate, a second buffer layer disposed on the first buffer layer, and a second buffer layer disposed on the second buffer layer. A first conductivity type semiconductor layer, an active layer disposed on the first conductivity type semiconductor layer, a second conductivity type semiconductor layer disposed on the active layer, and the first buffer layer corresponding to the pattern portion of the substrate A void layer may be included. By further forming voids on the buffer layer, the embodiment has the effect of more effectively blocking defects caused by potential differences. |
