摘要： A light emitting layer made of a group III-V nitride semiconductor is formed between a first semiconductor layer made of an n-type group III-V nitride semiconductor and a second semiconductor layer made of a p-type group III-V nitride semiconductor. In side portions of the second semiconductor layer, oxidized regions are formed through the oxidization of the second semiconductor layer itself so as to be spaced apart from each other in the direction parallel to the plane of the light emitting layer. A p-side electrode is formed across the entire upper surface of the second semiconductor layer including the oxidized regions, and an n-side electrode is formed on one surface of the first semiconductor layer that is away from the second semiconductor layer.
