The invention provides a light-emitting diode and a display device, the light-emitting diode comprises an epitaxial structure, the epitaxial structure is provided with a light-emitting surface and a back surface opposite to the light-emitting surface, the light-emitting surface comprises an edge area and a middle area surrounded by the edge area, the edge area is covered with an insulating layer, and the insulating layer is arranged on the back surface of the light-emitting surface. The area of the middle area accounts for 60%-99% of the area of the light-emitting face. The width of the insulating layer on the light emitting surface is between 5 microns and 20 microns, so that enough light emitting rate of the light emitting diode can be ensured, and meanwhile, the thickness of the insulating layer can be properly increased, so that the protection on the side wall of the light emitting diode is enhanced, and the influence on the performance of a device due to IR electric leakage is prevented. 本发明提供一种发光二极管及显示装
