Patent ID: 8120041

Claim:
A semiconductor light-emitting device, comprising: a first conductivity type first semiconductor layer; a luminous layer formed on the first semiconductor layer; a second conductivity type second semiconductor layer formed on the luminous layer; a transmissive substrate which is mounted on and joined to the second semiconductor layer and is pervious to the emission wavelength of the luminous layer; and a first reflecting layer which is formed under the first semiconductor layer and composed of stacked two or more first conductivity type semiconductor layers, and at least part of which has reflectivity for an emission wavelength of the luminous layer, wherein an electrode for reflecting layer use is formed on part of a surface of the first reflecting layer opposite from the first semiconductor layer, and wherein a second reflecting layer which has reflectivity for the emission wavelength of the luminous layer is formed on the surface of the first reflecting layer opposite from the first semiconductor layer, in an area other than an area where the electrode for reflecting layer use is formed.
