[0011] Figure 4 This is a schematic diagram of the structure of the common electrode of the gate metal layer in the prior art. As long as one defect occurs on the common electrode line of the gate metal layer of this structure, the common voltage on the common electrode cannot be applied, resulting in the failure of the entire common electrode. The failure of the wire leads to the generation of poor bright wires, and it is difficult to repair
