Claim Text:
1. A method for repairing a display device comprising steps of: (a) forming a gate and a scanning line, a first insulation layer, and a semiconductor layer on a substrate in sequence; (b) predefining a first region of the semiconductor layer associated with a position of a data line, and providing an etch stop layer on the semiconductor layer at a place deviating from the first region of the semiconductor layer; (c) modifying the first region of the semiconductor layer into a conductor; and (d) arranging a source, a drain, the data line, and a second insulation layer on the semiconductor layer, wherein, in the step (c), the first region of the semiconductor layer is modified into the conductor by being exposed to ultraviolet light; the data line, after being broken into several segments, can be repaired through welding of the segments respectively onto the conductor beneath the data line.
