Abstract
A semiconductor light-emitting device includes: a substrate; a first conductivity type layer formed on the substrate and including a plurality of group III-V nitride semiconductor layers of a first conductivity type; an active layer formed on the first conductivity type layer; and a second conductivity type layer formed on the active layer and including a group III-V nitride semiconductor layer of a second conductivity type. The first conductivity type layer includes an intermediate layer made of AlxGa1−x−yInyN (wherein 0.001≦x<0.1, 0<y<1 and x+y<1).
