Patent ID: 7196347

Claim:
A semiconductor light emitting device that is comprised of a III group nitride compound semiconductor that is expressed as Al x Ga y In 1−x−y N (where 0≦x≦1, 0≦y≦1, and 0≦x+y≦1), comprising: at least, a substrate, a multilayered reflection layer formed on the substrate, a superlattice layer formed on the multilayered reflection layer, and a light emitting portion formative layer that sequentially includes at least a second conductivity type semiconductor layer and first conductivity type semiconductor layer, that are formed on the superlattice layer, in the order mentioned, wherein a first electrode is electrically connected to the first conductivity type semiconductor layer that consists of a n-type or p-type semiconductor, and a second electrode is electrically connected to the second conductivity type semiconductor layer that consists of a n-type or p-type semiconductor having a polarity opposite to that of the first conductivity type semiconductor layer, or the superlattice layer.
