Abstract

The invention discloses a TFT-LCD (thin film transistor liquid crystal display) array substrate which comprises a substrate, and a first transparent conductive film, a grid layer, a gate insulating layer and a source drain electrode layer which, from top to bottom, are sequentially formed on the substrate, wherein the grid layer comprises a grid line and a common electrode wire, the source drain electrode layer comprises a data line and a transistor, the first transparent conductive film at least comprises a first part and a second part which are not contacted with each other, the first part is arranged below an area at which the data line is located, and not contacted with the grid line and the common electrode wire. According to the array substrate disclosed by the embodiment of the invention, when the data line is open-circuit, the part of the conductive film and the data line can be welded together directly by using a laser welding technology, thereby achieving the purpose of repairing the data line.

Description

technical field [0001] The invention relates to the field of thin film transistor liquid crystal display, in particular to a TFT-LCD array substrate and a manufacturing and repairing method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the advantages of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. Advanced-Super Dimensional Switching (AD-SDS) generates a fringe electric field through the electrodes between pixels in the same plane, so that the aligned liquid crystal molecules between the electrodes and directly above the electrodes can be in the plane direction, that is, parallel to the substrate. The direction produces a rotation conversion, which improves the light transmission efficiency of the liquid crystal layer while increasing the viewing angle. [0003] The AD-SDS type TFT-LCD array substrate in the prior art generally includes the f...
