Claim 0:
1. A light-emitting diode, comprising:
a first type semiconductor layer having an upper surface;
a stress relief layer that is disposed on said upper surface of said first type semiconductor layer and that includes at least one first repeating unit containing a first well layer and a first barrier layer being alternately stacked;
an active layer that is disposed on said stress relief layer opposite to said first type semiconductor layer and that includes at least one second repeating unit containing a second well layer and a second barrier layer being alternately stacked;
a second type semiconductor layer disposed on said active layer opposite to said stress relief layer;
a first electrode electrically connected to said first type semiconductor layer; and
a second electrode electrically connected to said second type semiconductor layer,
wherein, said first well layer is made of a material including In; said second well layer is made of a material including In; said second barrier layer is formed with multiple sub-layers, each of said sub-layers being made of a material including Al.
