Abstract
A light emitting diode includes an n-type nitride semiconductor layer, a V-pit generation layer located over the n-type nitride semiconductor layer and having a V-pit, an active layer located on the V-pit generation layer, and a p-type nitride semiconductor layer located on the active layer. The active layer includes a well layer, which includes a first well layer portion formed along a flat surface of the V-pit generation layer and a second well layer portion formed in the V-pit of the V-pit generation layer. The light emitting diode emits light having at least two peak wavelengths at a single chip level.
