Abstract
In a nitride semiconductor LED having a light emitting structure, an n-doped semiconductor layer has a first region and a second region surrounding the first region, an active layer is formed on the second region of the n-doped semiconductor layer, and a p-doped nitride semiconductor layer is formed on the active layer. A p-electrode is formed on the p-doped semiconductor layer. An n-electrode is formed on the first region of the n-doped nitride semiconductor layer.
