Semiconductor light-emitting devices including contact layers to form reflective electrodes
A semiconductor light-emitting device includes a contact layer. The contact layer has the composition ratio of Al elements which varies gradually therein. A region formed by an Al element in the contact layer of the semiconductor light-emitting device may improve light extraction efficiency of the light emitted from an active layer and facilitate a formation of the reflective electrode.
