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.
A thin film transistor (TFT) array substrate, comprising a pixel region, a wiring region disposed outside the pixel region, and driving integrated circuits, the wiring region has a wiring layer comprised of scan or data wirings, the scan or data wirings are electrically connected to the driving integrated circuits accordingly, wherein a repair wiring layer comprised of only one spiral-shaped repair wiring is disposed insulatedly below or above the wiring layer in the wiring region, with sections of the spiral-shaped repair wiring being respectively arranged between adjacent scan or data wirings, each of the scan or data wirings has a first set of intersections and a second set of intersections with a repair wiring section of the spiral-shaped repair wiring, each of the sets of intersections of at least one of the scan or data wirings has more than one intersection, when the scan or data wiring is broken, a repair wiring section is cut off the spiral-shaped 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.
