Claim 0:
1. A light-emitting device comprising:
a reflective layer comprising a plurality of nano-structures two-dimensionally disposed regularly and a low-refractive-index layer disposed adjacent to the plurality of nano-structures;
a first electrode disposed on the reflective layer;
an organic emission layer disposed on the first electrode; and
a second electrode disposed on the organic emission layer,
wherein each of the plurality of nano-structures comprises a non-metallic material, and the low-refractive-index layer comprises a dielectric material having a second refractive index lower than a first refractive index of the non-metallic material, and
wherein the non-metallic material comprises at least one of BaTiO3, Cr2O3, HfO2, ZnS, ZnSe, GaP, InP, GaAs, GaN, and AlAs2.
