Embodiment 1

[0032] combine Figure 2a and 2b As shown, Embodiment 1 of the present invention provides an array substrate 10, including a substrate 11, data lines 12 and gate lines 13 formed on the substrate 11, and the data lines 12 and gate lines 13 intersect to form pixel regions. Specifically, a gate insulating layer 18 is formed above the gate line 13 , and the data line 12 is formed on the gate insulating layer 18 .

[0033] The array substrate 10 further includes a common electrode 15 and a connection electrode 17 formed on the substrate 11 , the common electrode 15 is located in the pixel area and does not cover the area corresponding to the data line 12 . The connection electrode 17 is connected to the common electrode 15 in adjacent pixel regions, and the projection of the connection electrode 17 on the substrate 11 intersects and does not completely overlap with the projection of the data line 12 on the substrate 11 .

[0034] Such as Figure 2b Shown, provided for embodiment...

Embodiment 2

[0045] Embodiment 2 of the present invention provides an array substrate 10. The difference between Embodiment 2 and Embodiment 1 is that the relative positions of the common electrode 15, the pixel electrode 14 and the first protective layer 16 are different, and Embodiment 2 increases The second protective layer 19 is added. In Embodiment 1, the pixel electrode 14 and the data line 12 are arranged in the same layer, and the common electrode 15 is formed on the first protection layer 16 . However, in Embodiment 2, both the pixel electrode 14 and the common electrode 15 are arranged in different layers from the data line 12, the pixel electrode 14 is formed on the first protection layer 16, and the second protection layer is formed on the data line 12, The common electrode 15 is disposed on the second protection layer 19 . Other structures of the array substrate in Embodiment 2 are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0049] Embodiment 3 of the present invention also provides a display panel. The display panel includes the array substrate 10 as described above. Further, the display panel may also include a color filter substrate 20 on which a black matrix is ​​arranged. twenty one.

[0050] By removing the common electrode above the data line, the common electrode is only located in the pixel area, and the common electrode of the adjacent pixel area is connected through the connecting electrode, and the projection of the connecting electrode on the substrate does not completely cover the area corresponding to the data line, reducing data. The area of ​​the electrode above the line, that is, a relatively small connecting electrode is provided to connect to the common electrode of the adjacent pixel area, thereby reducing the probability of short circuit between the common electrode and the data line.

Abstract

The invention provides an array substrate, a display panel and a display device. Common electrodes of the array substrate are only located in pixel regions, the common electrodes in the adjacent pixel regions are connected through a connecting electrode, the projection of the connecting electrode on a substrate body does not completely cover regions corresponding to data lines, the area of the electrodes above the data lines is reduced, in other words, the connecting electrode with a small area is arranged to make the common electrodes in the adjacent pixel regions communicated, and thus the probability of short-circuiting of the common electrodes and the data lines is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] combine Figure 1a and Figure 1b As shown, an existing array substrate 10 includes: a substrate 11 , data lines 12 , gate lines 13 , pixel electrodes 14 and common electrodes 15 , and the data lines 12 and gate lines 13 intersect to form pixel regions. The common electrode 15 is strip-shaped, located in the entire pixel area and above the data line 12, and corresponds to the position of the black matrix 21 on the color filter substrate 20, and there are gaps between the common electrodes 15 in each pixel area. The pixel electrode 14 is plate-shaped and arranged on the same layer as the data line 12 . An electric field is formed between the common electrode 15 and the pixel electrode 14 to drive the liquid crystal molecules to rotate. The common electrode 15 above the data line 12 p...
