Claim Text:
1. A semiconductor light emitting device comprising: a light emitting element including a semiconductor layer, the semiconductor layer having a first face, a side surface continued from the first face, and an active layer configured to emit a light, a p-side electrode provided on the semiconductor layer, and an n-side electrode provided on the semiconductor layer; a p-side interconnection portion being electrically connected to the p-side electrode; an n-side interconnection portion being electrically connected to the n-side electrode; an insulating material disposed on the side surface of the semiconductor layer, a periphery of the p-side interconnection portion, and a periphery of the n-side interconnection portion, the insulating material blocking light emitted by the light emitting element; a phosphor layer disposed on the insulating material and the first face of the semiconductor layer, the phosphor layer comprising a transparent medium, phosphor dispersed in the transparent medium, and particles dispersed in the transparent medium, the phosphor, when excited by the light, emitting a fluorescence, the particles being of a magnitude of not more than 1/10 of a wavelength of the light and having a refractive index that is different from a refractive index of the transparent medium; and a fluorescent reflection film provided between the light emitting element and the phosphor layer, the fluorescent reflection film having a reflectance with respect to a wavelength of the fluorescence emitted by the phosphor that is greater than a reflectance with respect to the wavelength of the light, the fluorescent reflection film being in contact with a substantial portion of the first face of the semiconductor layer and a surface of the insulating material disposed on the side surface of the semiconductor layer.
