摘要：
A semiconductor light-emitting device includes a semiconductor light-emitting element emitting light in a region ranging from ultraviolet to visible, and a visible-light luminescent element absorbing light emitted from the semiconductor light-emitting element and outputting visible light. The visible-light luminescent element includes a substrate, a light-reflecting layer formed on the substrate and containing light scattering particles, and a luminescent layer containing phosphor particles. The luminescent layer absorbs light emitted from the semiconductor light-emitting element and output visible light. The luminescent layer further absorbs light that is emitted from the semiconductor light-emitting element, arrives at and is reflected from the light scattering particles, and output the visible light.
