ABSTRACT:
A surface emission type semiconductor light-emitting device includes a substrate, a distributed Bragg reflector formed on the substrate, a light-emitting region formed on the distributed Bragg reflector, a first contact layer, formed on a portion of the light-emitting region and transparent to a wavelength of light emitted from the light-emitting region, for supplying a current to the light-emitting region, and a second contact layer, formed on the light-emitting region to cover a side portion of the first contact layer, for forming a current blocking barrier between the light-emitting region and the second contact layer and supplying the current to the first contact layer.
