An AC electroluminescent power cord includes at least two electrode wires and a luminescent layer. The electrode wire is coated with the luminescent layer; the transparent or translucent plastic layer is coated on an outer wall of the luminescent layer; and each of the at least one electrode wire includes at least one metal wire; the at least two electrode wires are insulated with each other. When the electrode wires are conducted with an AC power source, the luminescent layer emits light. The AC electroluminescent power cord of the disclosure not only has a simple and reliable structure, but also has a display function. When applied for various electronic devices, the AC electroluminescent power cord of the disclosure integrally emits light or sequentially emits light in sections to simulate and display the current flow.
