The present invention relates to a GaN series light-emitting diode structure, which includes a substrate; at least one GaN series layer formed over the substrate; subsequently an interface blocking structure composed of an n-type GaN series superlattice structure and a GaN series light-emitting layer, and a GaN series light-emitting layer are formed over the GaN series layer; and a p-type GaN series layer formed over the GaN series light-emitting layer. In the present invention, the radiative recombination efficiency is improved by introducing an interface blocking structure before the light-emitting layer under the epitaxial conditions of low temperature and pure nitrogen atmosphere.
