ABSTRACT:
A semiconductor light-emitting device includes a first LED chip whose emitted light is wavelength-converted by a fluorescent substance layer formed by applying and curing a fluorescent substance material, and a second LED chip whose emitted light is not wavelength-converted by the fluorescent substance layer, wherein the first LED chip and the second LED chip are arranged on a substrate in such a way that a level of an emission layer of the second LED chip is higher than that of a top face of the first LED chip above the substrate.
