A group III nitride semiconductor light emitting device with a satisfactory ohmic contact is provided. The group III nitride semiconductor light emitting device includes a junction JC which tilts with respect to the reference plane that is orthogonal to a c-axis of a gallium nitride based semiconductor layer. An electrode forms the junction with the semipolar surface of the gallium nitride based semiconductor layer. The oxygen concentration of the grown gallium nitride based semiconductor layer that will form the junction JC is reduced. Since the electrode is in contact with the semipolar surface of the gallium nitride based semiconductor layer so as to form the junction, the metal-semiconductor junction has satisfactory ohmic characteristics. |
