LCD device and repairing method thereof

Abstract

The invention relates to a liquid crystal display device and a repair method thereof. The liquid crystal display device is composed of a pixel electrode, shading bars positioned on both sides of the pixel electrode and used for preventing light leakage, and a transistor correspondingly connected with the pixel electrode, wherein metal connection wires connected with the shading bars are also arranged at both sides of the shading bars; and convex bars are formed along the corresponding direction of the shading bars. The liquid crystal display device and the repair method thereof can repair point defects to become a display unit which can normally display, besides, the invention can realize the repair of three continuous defects and more than three point defects, enhance the display qualityof the liquid crystal display and improve the qualified rate of products.

Description

technical field [0001] The invention relates to a liquid crystal display device and a repairing method thereof, in particular to a liquid crystal display device for repairing point defects and a repairing method thereof. Background technique [0002] Twisted nematic (Twist Nematic, TN) thin film transistor liquid crystal display (TFT-LCD) is jointly formed by an array substrate, a color filter substrate and liquid crystal filled between the two substrates. The array substrate includes grid scanning lines and common electrode lines arranged parallel to each other, while crossing the data lines intersecting the grid scanning lines, there is a metal light-shielding strip on the same layer as the grid scanning lines on both sides of the data lines. [0003] In the engineering manufacturing process, due to process errors, garbage pollution and other reasons, point defects will inevitably appear in the liquid crystal display device. Point defects are generally divided into bright...

AI Technical Summary

Problems solved by technology

[0006] 1. Only bright spot defects can be repaired, and the repaired bright spot defects become dark spot defects;

[0007] 2. Unable to repair 3 or more point defects in a row

Because using the traditional method, after modifying 3 or more consecutive bright spot defects into dark spot defects, the product will still be judged as unqualified;

[0008] 3. It is impossible to achieve a repair effect that meets the specification requirements for a large number of scattered point defects in the display area
