Abstract

The invention relates to a TFT-LCD array substrate and a method for manufacturing the same and a method for repairing broken lines. The TFT-LCD array substrate comprises grid lines, statistical lines, common electrode lines, pixel electrodes and thin film transistors. The common electrode lines have a matrix structure with interconnected horizontal electrode lines and vertical electrode lines. The horizontal electrode lines and the vertical electrode lines are arranged at the same layer as the grid lines. The horizontal lines have an integral structure while the vertical electrode lines have a disconnected structure located below the statistical lines and are linked with at least one connecting line to form an integral unit. The present invention, by the common electrode lines which form the matrix structure on the substrate, guarantees the same common voltage of each position of the common electrode lines and the accuracy of liquid crystal deflection, and enhances display quality. The method for repairing broken lines of the invention realizes grid line repair or statistical line repair through the matrix-shaped common electrode lines. In this way, repair is made less difficultlyand more conveniently with higher success rate, and poor performance caused by broken grid lines or broken statistical lines is effectively avoided.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and its manufacturing and maintenance method, in particular to a TFT-LCD array substrate and its manufacturing and disconnection repairing method. 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 a TFT-LCD array substrate and a color filter substrate that are boxed together and the liquid crystal is sandwiched between them. The TFT-LCD array substrate is formed with gate lines, data lines, common electrode lines and arranged in a matrix. The thin film transistors and pixel electrodes of the color filter substrate are formed with a black matrix, color resin and common electrodes. By controlling the voltag...
