Problems solved by technology

And because the common electrode line is generally formed at the same time as the gate metal line in the process, the two are distributed on the same layer with a certain distance between them. However, in order to maximize the transmittance of the display screen, the common electrode line is generally relatively thin, resulting in relatively low impedance. Large; at the same time, there is overlapping capacitance betw

Abstract

The invention belongs to the technical field of displaying, and discloses an array substrate and a manufacturing method thereof, and a display device. According to the manufacturing method for the array substrate, the conventional thin film transistor (TFT)-liquid crystal display (LCD) array substrate manufacturing process by taking the conventional transverse electric field or multi-dimensional electric field as a drive is improved, so that public electrode wires and grid wires are distributed on different layers; therefore, on the premise that the light transmittance is not influenced, the widths of the public electrode wires are increased, the impedance of the publish electrode wires is reduced, and the uniformity and the voltage fluctuation of voltage of public electrodes can be quickly attenuated; moreover, overlap capacitance does not exist between data wires and the public electrode wires; distances between the data wires and the transparent public electrodes are enlarged; the coupling capacitance is reduced; crosstalk of a data signal on the voltage of a public electrode network is obviously reduced; the voltage of the public electrodes is uniform and stable; and the display quality is greatly improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat panel display market. The main structure of the TFT-LCD includes an array substrate and a color filter substrate in a box, where gate lines, data lines, and thin film transistors and pixel electrodes arranged in a matrix are formed on the array substrate. The display principle of TFT-LCD is: use the thin film transistor as a switch to apply a driving electric field to the liquid crystal to control the rotation of the liquid crystal, thereby controlling the display process of the TFT-LCD. Wherein, the driving electric field is generate...
