Abstract
The invention belongs to the technical field of display driving, and particularly relates to a driving circuit repairing device and a display panel, and the repairing device comprises a first repairing line which is arranged between a first gate driving circuit and a display area; the second repairing line is arranged between the second gate driving circuit and the display area; the third repairing line is arranged between the first repairing line and the display area; and the signal repairing circuit is used for repairing the driving signal introduced on the first repairing line when the nth GOA unit of the second gate driving circuit is abnormal, so that the repaired driving signal drives the nth scanning line on the second side of the display area through the second repairing line, meanwhile, the nth scanning line on the first side of the display area is driven through the third repairing line; according to the invention, the consistency of the repairing signal is ensured while the abnormal GOA unit is repaired, and the repairing precision is improved.
