Pixel driving circuit film layer, display screen and display equipment

The embodiment of the utility model provides a pixel driving circuit film layer, a display screen and display equipment. The pixel driving circuit film layer comprises a grid electrode part, an interlayer dielectric layer, a first wiring layer, a second wiring layer and a first planarization layer, the interlayer dielectric layer is arranged on the gate portion, the first wiring layer is arranged on the side, away from the gate portion, of the interlayer dielectric layer, the second wiring layer is arranged on the side, away from the gate portion, of the first wiring layer, and the first planarization layer is arranged on the side, away from the gate portion, of the second wiring layer; the first wiring layer and the second wiring layer are electrically connected, the first wiring layer and the second wiring layer are used for connecting a power supply voltage positive electrode and a data signal, equivalently, the cross sectional area of the wiring is increased or the wiring is connected in parallel, so that the resistance of the Vdd wiring and the Vdata wiring is reduced, the IR drop phenomenon can be relieved, the screen load is reduced, and the display effect is improved.
