TFT-LCD (Thin Film Transistor-Liquid Crystal Display) array substrate

Abstract

The invention relates to a TFT-LCD (Thin Film Transistor-Liquid Crystal Display) array substrate. The TFT-LCD array substrate comprises grid lines, data lines, pixel electrodes and a thin film transistor which are formed on the substrate, wherein at the intersection of the grid lines and the data lines, the grid lines at both sides of the data lines are connected by a grid connecting line which forms a double-point or multi-point intersection structure with the data lines; the grid connecting line comprises at least two first grid connecting lines; and the first grid connecting lines and the grid lines are made of the same material and are positioned at the same layer. By arranging at least two first grid connecting lines to intersect the data lines at the intersection, the invention lowers the probability of short circuit failure of the grid lines, and lowers the probability of open circuit failure of the grid lines. Meanwhile, the TFT-LCD array substrate provided by the invention also has the advantages of simple repairing process, fewer procedures, short time, high maintenance success rate and the like when the grid lines are subjected to short circuit and open circuit failure.
