Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display device, and a method for manufacturing the array substrate. Background technique [0002] The array substrate of the display device includes a base substrate, a plurality of gate lines and data lines on the base substrate intersecting each other to define pixel areas, and electrodes located in each of the pixel areas. by figure 1 For example, such as figure 1 As shown, two gate lines 10 and three data lines 20 intersect each other to define two pixel areas, and an electrode 30 is arranged in each pixel area, wherein, taking the electrode 30 as a pixel electrode as an example, figure 2 The structure diagram described is figure 1 The cross-sectional view of the array substrate shown in the AA' direction, such as figure 2 As shown, two adjacent electrodes 30 are located on the same layer with a certain distance between them.

Problems solved by technology

When the size of the pixel area is getting smaller and smaller, in order to keep the pixel area with a certain aperture ratio, the current spacing between adjacent electrodes (that is, figure 1 and figure 2 The d) in d) becomes smaller and smaller, so that when the display device including the array substrate is driven, the electric field between adjacent electrodes will interfere with each other, so that the liquid crystal deflection of the display device is disordered, which may cause light leakage and color mixing of the display device , seriously affecting the display quality of the display device; for example, if image 3 As shown, taking the electrode 30 above the data line 20 as a pixel electrode, and the distance between adjacent pixel electrodes is 10 microns (that is, d=10 microns) as an example, the light leakage of the array substrate is tested, according to the test As a result, it can be seen that liquid crystal a, which should not be deflected, is deflected, causing light leakage on the array substrate at the corresponding position of liquid crystal a.

[0004] To sum up, at present, for high-resolution array substrates, the electric fields between adjacent electrodes contained in them will interfere with each other, causing the liquid crystal deflection of the display device including the array substrate to be chaotic, which may cause light leakage and color mixing of the display device, seriously affecting The display quality of the display device
