It should be explained that the shielding electrodes 1031 are disposed to right correspond to the data lines 1021 one by one. Namely, the orthographic projection of the shielding electrode 1031 on the substrate 101 at least partially coincides with the orthographic projection of the data line 1021 on the substrate 101.

In another embodiment, the substrate 101, the data wiring layer 102, and the electrical field shielding layer 103 are sequentially stacked on one another. Namely, the electrical field shielding layer 103 is disposed above the data wiring layer 102. Namely, the present application can dispose relative locations of the electrical field shielding layer 103 and the data wiring layer 102 according actual processes.

In the embodiment of the present application, the electrical field shielding layer 103 further comprises a plurality of scan lines 1032. The scan lines 1032 are disposed along a second direction and are spaced at intervals. The scan lines 1032 and the shielding electrodes 1031 are disposed in a same layer. It should be explained that the array substrate 10 not only needs to dispose the data wiring layer 102 on the array substrate 10 to form the data lines 1021 but also needs to dispose a scan wiring layer on the array substrate 10 to form the scan lines 1032. The embodiment of the present application forms the scan lines 1032 and the shielding electrodes 1031 on the same layer to lower an entire thickness of the array substrate 10 and also simplify manufacturing processes.
It can be understood that the electrical field shielding layer 103 in the embodiment of the present application simultaneously forms the scan lines 1032 and the shielding electrodes 1031. Namely, the electrical field shielding layer 103 in the embodiment of the present application is a scan wiring layer, and it not only forms the scan lines 1032, but also forms the shielding electrodes 1031.
Specifically, the shielding electrodes 1031 comprises a plurality of sub-shielding electrodes 10311. The sub-shielding electrodes 10311 are disposed along the second direction and are spaced at intervals. It should be explained that because the electrical field shielding layer 103 comprises the scan lines 1032 and the shielding electrodes 1031, to make the scan lines 1032 insulated from the shielding electrodes 1032, the shielding electrodes 1031 need to be divided into the sub-shielding electrodes 10311.
For one shielding electrode 1031, the shielding electrode 1031 comprises the sub-shielding electrode 10311, the sub-shielding electrodes 10311 are disposed along the second direction and are spaced at intervals, and one sub-shielding electrode 10311 corresponding to one shielding electrode 1031 is disposed between adjacent two of the scan lines 1032. For the shielding electrodes 1031, each of the shielding electrodes 1031 comprises the sub-shielding electrodes 10311, and the sub-shielding electrodes 10311 corresponding to one shielding electrodes 1031 are disposed along the second direction and are spaced at intervals, and the sub-shielding electrodes 10311 corresponding to the shielding electrode 1031 are disposed between adjacent two of the scan lines 1032.
In the embodiment of the present application, the electrical field shielding layer 103 further comprises a plurality of first connection electrodes 1033. a plurality of first connection electrodes 1033 are disposed along the second direction and are spaced at intervals. One first connection electrode 1033 is disposed between adjacent two of the scan lines 1032, and the sub-shielding electrode 10311 between the adjacent two of the scan lines 1032 is connected to a corresponding one of the first connection electrodes 1033.
Each of the first connection electrodes 1033 has a signal connection terminal disposed on the first connection electrode 1033, and the signal connection terminal is configured to receive electrical signals. In the embodiment of the present application, the sub-shielding electrode 10311 between adjacent two of the scan lines 1032 receives electrical signals through a corresponding one of the first connection electrodes 1033.
The array substrate provided by the embodiment of the present application 10, disposes the shielding electrodes 1031 to right correspond to the data lines 1021 to shield an electrical field generated by charges on the data lines 1021 to prevent interfere with the pixel electrodes causing negative effects such as light leakage and crosstalk. Because the shielding electrodes 1031 right correspond to the data lines 1021, a pixel aperture rate can be improved.
In the embodiment of the present application, a voltage of a signal on the shielding electrode 1031 is less than a minimum value of a voltage of a signal on the data line 1021, or the voltage of the signal on the shielding electrode 1031 is greater than the maximum value of the voltage of the signal on the data line 1021. For example: the voltage of the signal inputted into the data line 1021 is A volts to B volts. The voltage of the signal inputted into the shielding electrode 1031 is less than A volts, or, the voltage of the signal inputted into the shielding electrode 1031 is greater than B volts, and A is less than B. Namely, the voltage of the signal inputted into the shielding electrode 1031 is out of a variable range of the voltage of the signal inputted into the data line 1021.
It should be explained that when the array substrate 10 are formed by four mask processes, a polycrystalline silicon layer is generally disposed under the data wiring layer 102. The embodiment of the present application setting the voltage of the signal inputted into the shielding electrode 1031 out of the variable range of the voltage inputted into the data line 1021 can prevent the polycrystalline layer between the data wiring layer 102 and the electrical field shielding layer 103 from having variation of electrical characteristics due to switch of positive and negative polarities of signals on the data lines 1021 and resulting in fluctuation of the voltage of the signal on the shielding electrode 1031 generating horizontal crosstalk.

It should be explained that the embodiment of the present application forms the second connection electrode 1022 on the data wiring layer 102 and makes the second connection electrode 1022 connected to the sub-shielding electrodes 10331 disposed along the second direction and are spaced at intervals such that all of the shielding electrodes 1031 on the array substrate are electrically connected. Hence, the embodiment of the present application only needs to dispose one connection terminal on the array substrate 10, and the connection terminal receives electrical signals.
Furthermore, in the embodiment of the present application, because the width of the shielding electrode 1031 is greater than the width of the data line 1021, the width of the second connection electrode 1022 can be set as a difference between the width of the shielding electrode 1031 and the width of the data line 1021 such that the orthographic projection of the shielding electrode 1031 on the substrate coincides with the orthographic projection of the data line 1021 on the substrate and the orthographic projection of the second connection electrode 1022 on the substrate 101 to improve the pixel aperture rate.
