ABSTRACT:
A semiconductor light-emitting device capable of attaining a surface plasmon effect while attaining excellent ohmic contact is provided. This semiconductor light-emitting device comprises a semiconductor layer formed on an emission layer, a first electrode layer formed on the semiconductor layer and a second electrode layer, formed on the first electrode layer, having a periodic structure. The first electrode layer is superior to the second electrode layer in ohmic contact with respect to the semiconductor layer, and the second electrode layer contains a metal exhibiting a higher plasma frequency than the first electrode layer.
