1. A light-emitting diode, comprising:
a first semiconductor layer;
a light-emitting layer disposed on the first semiconductor layer;
a second semiconductor layer disposed on one side of the light-emitting layer away from the first semiconductor layer and located on a light-emitting surface of the light-emitting layer; and
a first protective layer disposed on one side of the second semiconductor layer away from the light-emitting layer;
wherein the light-emitting diode comprises at least one convergence surface, and the at least one convergence surface comprises a surface of the second semiconductor layer away from the light-emitting layer or a surface of the first protective layer away from the second semiconductor layer;
wherein the surface of the second semiconductor layer away from the light-emitting layer is a first convergence surface, and the first convergence surface protrudes outward along a direction from the first semiconductor layer toward the light-emitting layer.
