Problems solved by technology

[0006] Since there are a large number of signal scanning lines in the display area, and there are a large number of overlapping points directly with the repairing lines, during the repairing process, other undotted signal scanning lines and the overlapping points of the repairing lines will generate coupling capacitance along with the signal scanning. The increase of the line keeps getting bigger, and the coupling capacitance between the repair line and the target liquid crystal electrode and the resistance of the repair line itself exist, thus affecting the normal repair of the repair line

Abstract

The invention provides a new repairing line structure, which comprises the original repairing lines, intermittent repairing lines and auxiliary repairing lines; the repairing lines are not directly overlapped with signal scan lines. The intermittent repairing lines are partially overlapped with two signal scan lines, or more than two signal scan lines are outspread as a unit. The intermittent repairing lines and the signal scan lines are overlapped into two or more rows. The manufacturing method of the repairing line structure is as follows: a metal film is arranged on a substrate through sputtering; a mask template forms intermittent repairing lines and auxiliary repairing lines outside a pixel area of the substrate through the exposure process and the chemical etching process; an electrode insulating layer film is arranged on the substrate; a metal film is deposited on the substrate; the mask template forms array substrate signal scanning electrodes through the exposure process and the chemical etching process, and forms the repairing lines outside the pixel area of the substrate at the same time. The repairing points are completely positioned in liquid crystal so as to avoid bad connections caused by oxidation corrosion; in addition, various repairing routes are provided to avoid incapable repairing due to the breaking of certain repairing line.

Description

technical field [0001] The invention relates to the field of liquid crystal display (TFT LCD), in particular to a repair line structure and a manufacturing method of a thin film transistor liquid crystal display. Background technique [0002] Liquid crystal display is a kind of passive display. It cannot emit light by itself and can only use the light of the surrounding environment. Since the liquid crystal display only needs a small amount of energy to display patterns or characters, it makes LCD a better display method. The liquid crystal material used in liquid crystal display is an organic substance with both liquid and solid properties. Its rod-like structure is arranged in the liquid crystal cell, but its alignment direction can be changed under the action of an electric field. [0003] Generally, a liquid crystal display device has two upper and lower substrates 20 spaced apart from each other and facing each other. A plurality of electrodes formed on the two substra...
