The key component of the liquid crystal display is a liquid crystal panel composed of an array substrate and a color filter substrate.

In order to solve the problem of disconnection, the existing wiring design uses double-layer metal wiring for the wiring. When the first trace is abnormally disconnected, the second floating metal wire is welded to both ends of the disconnected first trace, and the line is reconnected. However, the wiring design is restricted by the width of the panel frame and the process conditions. For example, the etching amount of the wet etching process of the production line is large, which makes it impossible to design double-layer repair wiring at the non-display area end of some products, so that it is impossible to solve the problem of disconnection at the wiring end. line problem.

本发明通过在源极配线的上方横跨设置多条源极悬浮线，不仅解决了现有技术的由于配线端较窄以及蚀刻量太大的问题导致某些产品在信号线设置区域端无法设计双层修复走线来修复配线走线的问题，同时，还可以实现对显示区域像素数据线的修复。The present invention not only solves the problem in the prior art that some products are at the end of the signal line setting area due to the narrow wiring end and too much etching by setting a plurality of source suspension lines across the source wiring. It is impossible to design double-layer repair wiring to fix the problem of wiring wiring, and at the same time, it is also possible to repair the pixel data lines in the display area.
