1. A method of fabricating an AC light emitting device, comprising:

  • forming a first conductive type semiconductor layer, an active layer and a second conductive type semiconductor layer on a substrate;

    patterning the second conductive type semiconductor layer, the active layer and the first conductive type semiconductor layer to form a plurality of light emitting cells each including an isolated first conductive type semiconductor layer, a second conductive type semiconductor layer disposed on one region of the isolated first conductive type semiconductor layer, an active layer interposed between the isolated first conductive type semiconductor layer and the second conductive type semiconductor layer, and a photonic crystal structure formed in the second conductive type semiconductor layer; and

    forming metallic wirings electrically connecting the light emitting cells having the photonic crystal structures with one another.
