1. A light emitting diode, comprising:

  • an n-type contact layer;

    a p-type contact layer disposed over the n-type contact layer;

    an active region disposed between the n-type contact layer and the p-type contact layer and comprising a multi-quantum well structure including a quantum well layer;

    a p-type clad layer disposed between the p-type contact layer and the active region;

    a superlattice layer including a plurality of layers, disposed near the active region; and

    a spacer layer disposed between the superlattice layer and the n-type contact layer and having a bandgap smaller than that of the barrier layer and greater than that of the quantum well layer.
