Abstract
A semiconductor light-emitting device includes substrate (3), a plurality of light-emitting-element-layers (10a, 10b, 10c, . . . ) of semiconductor material formed on the substrate (3) so as to be isolated from each other and having a wider band gap than the substrate (3), and phosphors (15a, 15b, 15c, . . . ) converting wavelengths of light from the light-emitting-element-layers (10a, 10b, 10c, . . . ) into other wavelengths.
