Abstract: An organic light-emitting display panel, a display device, and an organic light-emitting display motherboard are provided. The organic light-emitting display panel includes a base substrate, a metal wire, a first insulation layer, and a conductive portion. The metal wire has an upper surface opposing to the base substrate. A material of the metal wire includes a first metal. The first insulation layer covers the upper surface of the metal wire and includes at least one hollow portion penetrating through the first insulation layer and exposing a portion of the upper surface of the metal wire. The conductive portion is electrically connected to the metal wire, and is not overlapped with the at least one hollow portion. A work function of a material of the conductive portion is G1, a work function of metal silver is G2, a work function of the first metal is G3, and G1>G2>G3.
