Abstract:
According to one embodiment, a light emitting device includes a light emitting layer, a first conductivity type layer, a first electrode, a second conductivity type layer, a current blocking layer and a second electrode. The first conductivity type layer is provided on the light emitting layer. The first electrode is provided on the first conductivity type layer. The second conductivity type layer is provided under the light emitting layer. The current blocking layer is provided in contact with a partial region of a surface of the second conductivity type layer, and has an outer edge protruding from an outer edge of the first electrode. The second electrode is in contact with a surface of the current blocking layer on opposite side from the second conductivity type layer and a region of the surface of the second conductivity type layer not in contact with the current blocking layer.
