tft-lcd array substrate and its manufacturing method and display screen

Abstract

The invention provides a thin film transistor (TFT) - liquid crystal display (LCD) array substrate and a manufacturing method thereof, and a display screen. The array substrate comprises a substrate body, a first metal layer, a gate line, a common electrode bus, a second metal layer, a data line and a common electrode wire, wherein the first metal layer is formed on the substrate body, and the grate line and the common electrode bus are located on the first metal layer and installed in parallel; and the second metal layer is formed on the first metal layer, the data line and the common electrode wire are located on the second metal layer, the data line and the common electrode wire cross the grate line and the common electrode bus, the data line and the common electrode wire are installed in parallel, and the common electrode wire is in electric connection with the common electrode bus. By means of the fact that the common electrode bus and the grate line are installed in parallel, the common electrode bus and an access line are installed in a crossed mode, so that the whole common electrode bus can be used for being connected with the access line. Therefore, common voltage is obtained from multiple points, and obtaining efficiency of the common voltage is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a TFT-LCD array substrate, a manufacturing method thereof, and a display screen. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display) has the advantages of low voltage, low power consumption, large amount of displayed information, easy colorization, etc., and occupies a dominant position in the current display market. It has been widely used in electronic equipment such as electronic computers, electronic notebooks, mobile phones, video cameras, and high-definition televisions. [0003] One of the most basic components of a TFT-LCD is a display screen, which includes a boxed array substrate and a color filter substrate, and a liquid crystal layer filling the gap between the array substrate and the color filter substrate. The basic principle of displaying images on the display screen is: by applying an electric field acting on the li...
