TFT-LCD array substrate

Abstract

The present invention relates to a TFT-LCD array substrate which comprises a grid line formed on a substrate, a data line, a pixel electrode and a thin film transistor. At the intersection part of grid line and data line, the grid lines which are positioned at two sides of data lines are connected through a grid connecting line which forms a two-point or multi-point intersection structure with the data line, and / or the data lines at two sides of grid line are connected through a data connecting line which forms a two-point or multi-point intersection structure with the grid line. The TFT-LCD array substrate according to the invention not only reduces the probability of inferior short circuit of grid line / data line, but also reduces the probability of grid line broken circuit or data line broken circuit through installing at least two first grid connecting lines intersected with the data line and / or installing at least two first data connecting lines intersected with the grid lines at the intersection. Simultaneously the TFT-LCD array substrate according to the invention also has the advantages of simple restoring, less working procedure, short time and high success rate of maintenance when the grid line / data line generates short circuit or inferior short circuit.

Description
