1. A light emitting device, comprising:

  • a first photonic crystal structure comprising a reflective layer and a plurality of non-metal pattern elements on the reflective layer;

    a second conductive semiconductor layer on both the reflective layer and the plurality of non-metal pattern elements;

    an active layer on the second conductive semiconductor layer;

    a first conductive semiconductor layer on the active layer;

    a non-conductive semiconductor layer on the first conductive semiconductor layer; and

    a first electrode layer on the first conductive semiconductor layer,wherein the non-conductive semiconductor and the first conductive semiconductor layer have a recess in which the first electrode layer is located.
