Abstract
A semiconductor light emitting device has a light emitting layer portion comprising AlGaInP layers formed on a GaAs substrate. A light reflecting layer portion comprising alternately laminated layers with different refractive indices is provided between the GaAs substrate and the light emitting layer portion. The light reflecting layer portion comprises Al.sub.w Ga.sub.1-w As.sub.1-v P.sub.v layers (where: 0.ltoreq.w.ltoreq.1, 0<v.ltoreq.0.05 w). An active layer which constitutes the light emitting layer portion comprises an (Al.sub.y Ga.sub.1-y).sub.0.51 In.sub.0.49 P layer (where: 0.ltoreq.y.ltoreq.0.7).
