Abstract
A thin film transistor array substrate and method for repairing the same are provided. Repairing lines are formed when the data lines on the thin film transistor array substrate are defined. Furthermore, the protruding portions and branches of common lines overlap with the repairing lines and the data lines respectively. The repairing method includes performing a laser welding operation to connect the common line with the data line, the repairing line or a scan line as well as removing a portion of the lines by laser. Thus, the thin film transistor array substrate and repairing method thereof can repair line defects and increase the manufacturing yield.
