发明名称 LIGHT-EMITTING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a light-emitting device which is excellent in heat resistance and has good color reproducibility.SOLUTION: There is provided a light-emitting device which includes: a substrate; a light-emitting element arranged on the surface of the substrate; a first resin layer which surrounds the side part of the light-emitting element and is arranged apart from the side part, on the surface of the substrate; and a second resin layer which is arranged so as to cover the light-emitting element and the first resin layer, on the surface of the substrate, and exists in the upper part of the light-emitting element, the upper part of the first resin layer, and a region between the light-emitting element and the first resin layer. The first resin layer contains a light-permeable resin, and a first fluorescent body which is excited by at least a part of light emitted from the light-emitting element and emits fluorescence. The second resin layer contains a light-permeable resin, and a second fluorescent body which is excited by at least a part of light emitted from the light-emitting element and emits fluorescence. The second fluorescent body has higher heat resistance than that of the first fluorescent body.
