A high-voltage alternating current (AC) light-emitting diode (LED) structure is provided. The high-voltage AC LED structure includes a circuit substrate and a plurality of high-voltage LED (HV LED) chips. Each one of the HV LED chips includes a first substrate, an adhering layer, first ohmic contact layers, epi-layers, a first insulating layer, at least two first electrically conducting plates, at least two second electrically conducting plates, and a second substrate. The HV LED chips manufactured by a wafer-level process are coupled to the low-cost circuit substrate to produce the downsized high-voltage AC LED structure.
