Thin film transistor (TFT)-liquid crystal display (LCD) array substrate and production method thereof

Abstract

The invention provides a thin film transistor (TFT)-liquid crystal display (LCD) array substrate and a production method of the TFT-LCD array substrate. Comb teeth of a comb-shaped repairing wire and comb teeth of a comb-shaped common electrode wire are arranged in an opposite mode, tail ends of the comb teeth of the comb-shaped repairing wire and the comb teeth of the comb-shaped common electrode wire are in a sharp shape, electrostatic charge on the repairing wire is removed by utilizing of a point discharge effect, the problem that a grid insulation layer separated by a data line is punctured to cause short circuits of the data line and the repairing wire due to the fact that too much electrostatic charge is gathered on the repairing wire is solved, and reliability and yield of a thin film transistor liquid crystal display are improved. Especially, the electrostatic charge gathered on the repairing wire is guided into the common electrode wire and is effectively removed by utilizing connection of the common electrode wire and a fixed potential.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a TFT-LCD array substrate and a manufacturing method thereof. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) 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] The thin film transistor liquid crystal display includes an array substrate and a color filter substrate that are boxed together, and a liquid crystal layer that fills the gap between the array substrate and the color filter substrate. The basic principle of the thin film transistor liquid crystal display to display images is: by applying an electric field acting on th...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of TFT-LCD array substrate and its manufacturing method, to solve the problem that in the existing TFT-LCD array substrate, the repair line is easy to accumulate a large amount of electrostatic charges, and the intersection position of the data line and the repair line is very easy to be caused by static electricity. Breakdown occurs due to discharge phenomenon, which leads to short circuit of data line and repair line, which reduces the reliability and yield of thin film transistor liquid crystal display.
