Abstract
A light-emitting diode structure for improving bonding yield is provided, which includes a light-emitting diode, a plurality of contact electrodes, an insulating layer structure, and a plurality of bonding electrodes. One surface of the light-emitting diode includes a mesa structure. The contact electrodes are on the mesa structure. The bonding electrodes are on the insulating layer structure and respectively cover at least one contact electrode. A surface of one of the bonding electrodes facing away from the light-emitting diode has a first platform and a second platform. The second platform is on the first platform. A surface area of a vertical projection of the second platform on the light-emitting diode is smaller than that of the first platform on the light-emitting diode, and said vertical projection of the second platform is within that of the first platform.
