Abstract
A TFT array substrate includes a pixel region and a wiring region disposed outside the pixel region. The wiring region has a wiring layer including scan or data wirings. A repair wiring layer including repair wiring is disposed insulatedly below or above the wiring layer. A scan or data wiring has a first intersection and a second intersection with a repair wiring section of the repair wiring. When the scan or data wiring is broken, a repair wiring section is cut off the repair wiring by a first cut-off point and a second cut-off point, and the broken scan or data wiring is electrically connected to the repair wiring section through soldering the first intersection and the second intersection. Thus, products that would otherwise be rejected in the manufacturing process of LCD panels can be repaired, which decreases the reject ratio, increases the yield and saves the production cost.
