Thin film transistor array panel and method for repairing the same

A thin film transistor substrate, comprising:

• a substrate including a display area including a plurality of pixels and a periphery area where a driver for driving the pixels is disposed;
• a plurality of first signal lines connected with the pixels and extended to the periphery area, the first signal lines including a first short-circuit portion provided in the periphery area;
• a plurality of second signal lines connected with the pixels and extended to the periphery area by crossing the first signal lines in an electrically insulated manner;
• first connection members overlapping lateral ends of the first signal lines, disposed in lateral sides with respect to the first short-circuited portion and formed of a semiconductor doped with a conductive impurity;
• and
• first repairing conductors overlapping the lateral ends of the first signal line, disposed in the lateral sides with respect to the first short-circuited portion, wherein lateral ends of the first connection member are connected with the lateral ends of the first signal line through contact holes.
