A semiconductor light-emitting device having a longitudinal direction, and able to smoothly incline luminance for the longitudinal direction is provided. The semiconductor light-emitting device comprises a substrate and a plurality of semiconductor light-emitting layers of a predetermined shape disposed in a row on the substrate. The semiconductor light-emitting layers have such a structure that light emission amount of light-emitting surface of each semiconductor light-emitting layer inclines from a side of one predetermined end toward a side of the other end for the direction of the row.
