It should be noted that the adjacent pixel electrode group 413 and the common electrode group 53 are defined as one group, and the following mainly takes two adjacent pixel electrode groups 413 and the common electrode group 53 as an example to describe in detail.

As shown in FIG. 3 and FIG. 4 , in one embodiment, the pixel electrode layer 41 and the common electrode layer 50 are arranged on the same layer. Specifically, the common electrode layer 50 is formed on the transparent conductive layer 40 , and the common electrode layer 50 is insulated from the pixel electrode layer 41 and arranged at intervals. The common electrode layer 50 and the pixel electrode layer 41 are prepared through the same transparent conductive layer 40, which can simplify the preparation process.

The polarity of the pixel electrodes 412 in the pixel electrode group 413 is opposite to that of the common electrodes 52 in the common electrode group 53 .

The pixel electrode groups 413 and the common electrode groups 53 are arranged alternately, and the voltage of the pixel electrodes 412 in the pixel electrode groups 413 is different from the voltage of the pixel electrodes 412 in the common electrode groups 53, so that the pixel electrode groups 413 can be connected to the common electrode groups 53 A horizontal electric field is formed to drive the liquid crystal 301 to deflect.

Specifically, the two pixel electrodes 412 in the pixel electrode group 413 are defined as the first pixel electrode 4131 and the second pixel electrode 4132 respectively, and the two common electrodes 52 in the common electrode group 53 are defined as the first common electrode 531 and the second pixel electrode 4132 respectively.

Wherein, according to the distance between the pixel electrode 412 and the common electrode 52, the intensity of the third horizontal electric field E3 is greater than the intensity of the first horizontal electric field E1, and greater than the intensity of the fourth horizontal electric field E4, and the intensity of the first horizontal electric field E1 is greater than The intensity of the second horizontal electric field E2, and the intensity of the fourth horizontal electric field E4 is greater than the intensity of the second horizontal electric field E2. This design method not only enables the liquid crystal 301 corresponding to the region between the pixel electrodes 412 and the liquid crystal 301 corresponding to the region between the common electrodes 52 to deflect, but also enables the corresponding liquid crystal 301 above the pixel electrodes 412 and the common electrode 52 to be deflected. The deflection can improve the display light effect and also increase the transmittance of the display panel 400 . Secondly, this embodiment does not need to change the structure of the array substrate 100 too much, it can effectively improve the situation that the liquid crystal 301 directly above the electrode is not rotated by the electric field force in the IPS mode, and does not need to add a new process, which can save costs and improve the effect obvious.

Further, the distance d1 between the first pixel electrode 4131 and the second pixel electrode 4132 is slightly smaller than the distance d2 between the adjacent second pixel electrode 4132 and the first common electrode 531, and slightly smaller than the distance d2 between the adjacent first pixel electrode 4132 and the first common electrode 531. The distance d3 between the electrode 4131 and the second common electrode 532 . The distance d4 between the first common electrode 531 and the second common electrode 532 is slightly smaller than the distance d2 between the second pixel electrode 4132 and the first common electrode 531, and slightly smaller than the distance d2 between the adjacent first pixel electrode 4131 and the second common electrode 4131. The spacing d3 between the electrodes 532 . The distance d3 between adjacent first pixel electrodes 4131 and second common electrodes 532 is equal to the distance d2 between adjacent second pixel electrodes 4132 and first common electrodes 531 . The distance d1 between the first pixel electrode 4131 and the second pixel electrode 4132 is equal to the distance d4 between the first common electrode 531 and the second common electrode 532 . This design method makes the intensity of the first horizontal electric field E1 equal to the intensity of the fourth horizontal electric field E4; since the distance between the two pixel electrodes 412 in the pixel electrode group 413 is smaller than that in the adjacent pixel electrode group 413 and the common electrode group 53 The distance between the adjacent pixel electrodes 412 and the common electrodes 52 makes the intensity of the first horizontal electric field E1 and the intensity of the third horizontal electric field E3 the same as possible, and due to the gap between the two common electrodes 52 in the common electrode group 53 The spacing between adjacent pixel electrode groups 413 and common electrode groups 53 is smaller than the spacing between adjacent pixel electrodes 412 and common electrodes 52, so that the intensity of the third horizontal electric field E3 is as equal as possible to the intensity of the fourth horizontal electric field E4, Therefore, the intensity of the second horizontal electric field E2 and the intensity of the fourth horizontal electric field E4 are as equal as possible, thereby making the intensity of the electric field in the display panel 400 more uniform, the deflection angle of the liquid crystal 301 is closer, and the display effect is better.

In other embodiments, the pixel electrode layer 41 and the common electrode layer 50 may be disposed on the same layer, and the materials of the pixel electrode layer 41 and the common electrode layer 50 are different. Alternatively, the pixel electrode layer 41 and the common electrode layer 50 are arranged in different layers, and in the direction perpendicular to the substrate 10, the pixel electrode 412 and the common electrode 52 are arranged and spaced apart from each other, and a horizontal layer is formed between the pixel electrode 412 and the common electrode 52. The electric field drives the liquid crystal 301 to deflect.
