Claim 3:
4. The light-emitting diode according to claim 1, wherein the light-emitting structure includes:
a P-type semiconductor layer;
an N-type semiconductor layer; and
a light-emitting stack interposed between the P-type semiconductor layer and the N-type semiconductor layer and including m layers of well layers and m+1 layers of barrier layers which are alternately stacked, wherein the well layers include at least one second well layer, at least one third well layer, at least one fourth well layer, and at least one fifth well layer, wherein a second indium concentration of the at least one second well layer is lower than a third indium concentration of the at least one third well layer and a fourth indium concentration of the at least one fourth well layer, and a fifth indium concentration of the fifth at least one well layer is the highest among all well layers.
