ABSTRACT:
A light-emitting device is provided, which includes a package having a first portion and a second portion surrounding it, a semiconductor light-emitting element mounted on the first portion and emitting a light having an emission peak in a near-ultraviolet region, a transparent resin layer covering the semiconductor light-emitting element and contacted with the package, and a laminated body formed on the transparent resin layer with end faces of the laminated body being contacted with the second portion. The transparent resin layer has an arch-like outer profile perpendicular cross section. The laminated body has an arch-like outer profile in perpendicular cross section and comprises a red fluorescent layer, a yellow fluorescent layer, a green fluorescent layer and a blue fluorescent layer laminated in the mentioned order. The yellow fluorescent layer has a top portion which is made larger in thickness than that of the end face portions thereof.
