Summary:PURPOSE: A light emitting device is provided to prevent dislocation by forming voids in a nitride semiconductor layer. CONSTITUTION: A light emitting structure (110) includes an active layer (114) on a substrate. The light emitting structure includes a first conductive semiconductor layer and a second conductive semiconductor layer on the substrate. A nitride semiconductor layer (107) is positioned between the substrate and the light emitting structure. The nitride semiconductor layer includes voids. The nitride semiconductor layer includes a first nitride semiconductor layer and a second nitride semiconductor layer.
