DISPLAY DEVICE AND TEST LINE REPAIR METHOD THEREFOR

摘要

A display device and a test line repair method therefor. The method comprises: respectively disconnecting a first input end and a first output end of a first thin-film transistor from a test signal input line (301) in a laser cutting manner; and connecting a first spare line (306) to a test signal output line (307) in a laser welding manner. The device and method therefor enable the width to length ratio of a display device not to be changed, so that no display exception will occur during lighting detection.
