Claim 18:
19. The display device according to claim 18, wherein:
the wiring layers comprise a first wiring layer and a second wiring layer; and
the driving backplane further comprises:
a first planarization layer covering the driving transistor, the first wiring layer being disposed on a surface of the first planarization layer away from the substrate and connected to the driving transistor;
a second planarization layer covering the first wiring layer, the second wiring layer being disposed on a side of the second planarization layer away from the substrate and connected to the first wiring layer;
a third planarization layer covering the second wiring layer, the light emitting function layer being disposed on a surface of the third planarization layer away from the substrate and connected to the second wiring layer; and
the bonding pads and the first wiring layer are disposed in the same layer, and the bonding holes are configured to penetrate the third planarization layer and the second planarization layer.
