1. A light-emitting device, comprising:

  • a substrate;

    an epitaxial structure on the substrate, wherein the epitaxial structure comprises at least a first conductivity type semiconductor layer, a light-emitting active layer, and a second conductivity type semiconductor layer;

    a first electrode on the first conductivity type semiconductor layer;

    a transparent conductive layer between the first electrode and the first conductivity type semiconductor layer; and

    a three-dimensional distributed Bragg reflector (DBR) layer between the transparent conductive layer and the first conductivity type semiconductor layer.
