Array substrate, display panel and display device

Abstract

The embodiment of the invention discloses an array substrate, a display panel and a display device and relates to the technical field of display. A display effect can be improved. The array substrate comprises a substrate base plate, multiple scan lines and multiple data lines, multiple subpixel zones defined by the multiple scan lines and the multiple data lines in an insulated and crossed mode, and thin film transistors, pixel electrodes and barrier metals correspondingly arranged in the subpixel zones. The orthographic projections of drain electrodes on the substrate base plate are located among the orthographic projections of every two adjacent data lines on the substrate base plate, and orthographic projections of the barrier metals on the substrate base plate are located among the orthographic projections of the drain electrodes on the substrate base plate and the orthographic projection of at least one of every two adjacent data lines on the substrate base plate. The scheme is mainly used for the liquid-crystal display device, the stray capacitance between the data lines and pixel electrodes is reduced, accordingly crosstalk caused by the stray capacitance is decreased, and a display effect is improved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of display technology, and in particular, to an array substrate, a display panel and a display device. [0003] 【Background technique】 [0004] The array substrate is an important part of the display device. The current array substrate includes a plurality of sub-pixel regions defined by a plurality of gate lines and a plurality of data lines, and also includes a thin film transistor and a pixel electrode corresponding to each sub-pixel region. The source of the thin film transistor is connected to the data line, and the drain of the thin film transistor is connected to the pixel electrode. [0005] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: [0006] As the resolution of the display device becomes higher and higher, the size of the sub-pixel area becomes smaller and smaller, and the distance between the data li...

AI Technical Summary

Problems solved by technology

[0006] As the resolution of the display device becomes higher and higher, the size of the sub-pixel area becomes smaller and smaller, and the distance between the data line and the drain electrode becomes smaller and smaller, so a parasitic capacitance is formed between the data line and the drain electrode, When the voltage on the data line changes, due to the influence of parasitic capacitance, crosstalk (Crosstalk) will occur on the voltage on the pixel electrode, which will adversely affect the display effect
