LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING SAME
A light-emitting device includes: a substrate; a light-emitting element mounted on the substrate, with a surface opposite to a light-emitting surface facing the substrate; a first resin encapsulant which covers the light-emitting element such that at least part of the light-emitting surface is exposed; and a second resin encapsulant provided on and in contact with the first resin encapsulant and the light-emitting surface. The first resin encapsulant contains a light reflective material. The second resin encapsulant has a function of converting first light emitted by the light-emitting element into second light of different wavelength, and a function of mixing the first light and the second light.
