Optionally, as shown in fig. 2, the encapsulation layer 6 covers a side of the organic light emitting layer away from the substrate 3, and is used for encapsulating the display panel, so as to isolate water and oxygen, and the better the insulating water and oxygen of the encapsulation layer 6 is, the longer the service life of the display panel is, and the encapsulation layer 6 has a stacked structure, for example, a stacked structure of an organic layer and an inorganic layer may be adopted, and the specific number of stacked layers is not specifically limited herein.

Alternatively, the second electrode 82 is connected to the source or drain of the thin film transistor in the pixel driving circuit 10 by a via hole penetrating the passivation layer and the planarization layer. After the organic light emitting diode 51 is supplied with the operating voltage, the first semiconductor layer 512 of the organic light emitting diode 51 generates electrons, the second semiconductor layer 513 generates holes, the holes and the electrons move to the middle light emitting layer 511 under the action of the electric field between the first electrode 81 and the second electrode 82, and when the holes and the electrons meet in the light emitting layer, energy is released, so that the light emitting layer 511 emits light, and the display panel displays images.

Then, T2 is turned on, and a drive current flows from the power supply (Vdd) through the organic light emitting diode 51 to the common signal line 11 via the power supply signal line 103, and the organic light emitting diode emits light by the drive current. After the T1 is turned off, the voltage of the gate layer 422 of the T2 is kept constant for the whole display period due to the holding effect of the storage capacitor Cs, so that the T2 is continuously turned on for the whole display period, and the driving current can flow from the power supply terminal (Vdd) through the organic light emitting diode 51 to the common signal line 11 via the power supply signal line 103 for the whole display period, thereby ensuring that the organic light emitting diode can normally emit light for the whole display period.

It should be noted that, in order to make the display panel have a better static shielding effect, the anti-static metal part may be a planar structure, so that the anti-static metal part has a larger static shielding area, and the static shielding effect is improved.

As shown in fig. 15, since the shift register 16 is located at the left side of the connection between the constant potential wiring 14 and the anti-static metal portion 7, the constant potential wiring 14 and the anti-static metal portion 7 can surround the shift register 16, when static electricity is introduced from the periphery of the display panel, the static electricity can be firstly attracted by the constant potential wiring 14 and the anti-static metal portion 7 and led out of the display panel, and since the orthographic projection of the shift register 16 on the plane of the display panel is overlapped with the constant potential wiring 41 and the anti-static metal portion 7, respectively, and the anti-static metal portion 7 is farther from the substrate with respect to the shift register 16, when static electricity is introduced into the display panel from the side of the array layer 4 away from the substrate 3, the static electricity can be firstly attracted by the anti-static metal portion 7 and led out of the display panel during the conduction of static electricity to the substrate 3, after the design is adopted, the shift register 16 can avoid the influence of static electricity introduced from the periphery of the display panel and the side far away from the substrate base plate 3, and the service life of the display device is further prolonged.

Specifically, as shown in fig. 1 and fig. 16, when at least two constant potential traces 41 are arranged in different layers and the anti-static metal part is connected to the constant potential trace 41, the range capable of shielding static electricity includes a film structure located between the anti-static metal part 7 and the constant potential trace 41 closest to the substrate, and because the constant potential trace 41 also has a certain anti-static capability and the constant potential trace 41 is located in the array layer 4, the constant potential trace 41 can perform an anti-static function on the film structure in the array layer 4, so that the film where the constant potential trace 41 is located receives dual anti-static protection, for example, when two constant potential traces 41 are arranged in different layers, the two film structures where the two constant potential traces 41 are located can receive dual anti-static protection of the constant potential trace 41 and the anti-static metal part 7, when three constant potential traces 41 are arranged in different layers, the three-layer film structure where the three constant potential wires 41 are located can be subjected to double anti-static protection of the constant potential wires 41 and the anti-static metal part 7, and when the three constant potential wires 41 are arranged in different layers, the three-layer film structure where the three constant potential wires 41 are located can be subjected to double anti-static protection of the constant potential wires 41 and the anti-static metal part 7, so that when at least two constant potential wires 41 are arranged in different layers, a better protection effect can be further achieved on the array layer 4, and the anti-static capability of the display panel is improved. In addition, the constant potential line 41 can be understood to be a surface formed in the thickness direction of the display panel by stacking each device and the film layers in the display panel, rather than penetrating through the multi-layer insulating film layer, in which static electricity enters the functional film layer in the display panel from the end surface of the display panel (for example, static electricity enters the film layer where the line for connecting the display device from the end surface of the display panel), as compared with static electricity entering the functional film layer from the upper and lower surfaces of the display panel. Therefore, when the constant potential wiring 41 is arranged in different layers, the electrostatic area can be resisted by the end face of the display panel, namely, when the constant potential wiring 41 is arranged in different layers, the constant potential wiring 41 can play a better anti-electrostatic role for a plurality of films, and particularly, the constant potential wiring 41 can better shield the static electricity from the edge of the display panel for devices or wirings in the film where the constant potential wiring 41 is arranged.
