Abstract

The invention provides a common electrode structure, a liquid crystal display panel and a manufacturing method thereof. The common electrode structure comprises several sections of metal wires arranged in sequence, wherein a disconnector is arranged between two adjacent metal wires. When the structure works, common voltage is provided to all the section of the metal wires. The structure can be used for testing array substrates conveniently, and provide the efficiency of detection production.

Description

technical field [0001] The invention belongs to the technical field of display panel production, and in particular relates to a common electrode structure, a liquid crystal display panel and a production method. Background technique [0002] The development of TFT-LCD has gone through a long period of basic research. After realizing large-scale and commercialization, TFT-LCD products have become more and more widely used due to their advantages of thinness, environmental protection and high performance. Whether it is a small-sized mobile phone screen, a large-sized notebook computer or monitor, or even a large-scale LCD TV, the application of TFT-LCD can be seen everywhere. [0003] GOA (Gate Driver on Array), POA (Photo Spacer on Array), and DBS (Data BlackMatrix Less), as new technologies developed by TFT-LCD, integrate more and more film structures on the array substrate. Therefore, the array substrate Stability is very important for product quality. In traditional TFT-...
