发明名称 SEMICONDUCTOR LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME
摘要 According to one embodiment, a semiconductor light emitting device includes a semiconductor layer, a p-side electrode, an n-side electrode, a fluorescent material layer and a reflection film. The semiconductor layer has a first surface and a second surface on an opposite side to the first surface and includes a light emitting layer. The p-side electrode and the n-side electrode are provided on the semiconductor layer on a side of the second surface. The fluorescent material layer is provided on a side of the first surface and includes a plurality of fluorescent materials and a bonding material. The bonding material integrates the fluorescent materials. The reflection film is partially provided on the fluorescent material layer and has a higher reflectance to the radiated light of the light emitting layer than to the radiated light of the fluorescent materials.
