ABSTRACT:
A semiconductor light emitting device can have stable electric characteristics and can emit light with high intensity from a substrate surface. The device can include a transparent substrate and a semiconductor layer on the substrate. The semiconductor layer can include a first conductive type semiconductor layer, a luminescent layer, a second conductive type semiconductor layer, and first and second electrodes disposed to make contact with the first and second conductive type semiconductor layers, respectively. The first conductive type semiconductor layer, the luminescent layer, and the second conductive type semiconductor layer can be laminated in order from the side adjacent the substrate. An end face of the semiconductor layer can include a first terrace provided in an end face of the first conductive type semiconductor layer in parallel with the substrate surface, and an inclined end face region provided nearer to the substrate than the first terrace. The first electrode disposed in the inclined end face region can reflect light emitted from the luminescent layer to the substrate.
