Display panel

The invention discloses a display panel, and a light-emitting device comprises a first electrode layer disposed on a substrate; the first light-emitting unit is arranged on the first electrode layer; the carrier generation layer is arranged on the first light-emitting unit, and the second light-emitting unit is arranged on the carrier generation layer; the second electrode layer is arranged on the second light-emitting unit; wherein the carrier generation layer comprises a first sub-film layer, the material of the first sub-film layer is transparent conductive oxide, and the two adjacent first sub-film layers of the two adjacent light-emitting devices are arranged at intervals. The first sub-film layer in the carrier generation layer is of the patterned structure, the conductivity of the first sub-film layer is high, the two adjacent first sub-film layers of the two adjacent light-emitting devices are arranged at intervals, current cannot be transmitted between the two adjacent light-emitting devices through
