1. A light-emitting device comprising:

  • a substrate;

    a light-emitting structure including first and second nitride-based semiconductor layers on the substrate, and an active layer between the first and second nitride-based semiconductor layers;

    an insulating layer on a top surface of the light-emitting structure;

    a protrusion on the insulating layer, a top surface of the protrusion being larger than a bottom surface thereof, the protrusion having a trapezoidal cross-section;

    a transparent conductive layer covering the top surface of the light-emitting structure, a top surface of the insulating layer, and the top surface of the protrusion; and

    an electrode covering at least one of inclined surfaces of the protrusion on the transparent conductive layer.
