Abstract: Provided are a method for repairing a display panel and a display panel repaired by using the same. The method for repairing a display panel of the inventive concept includes inspecting a display panel including pixels arranging along a first direction and a second direction crossing the first direction to detect a defective pixel among the pixels, and cutting an initialization voltage line disposed between the defective pixel detected in the detecting of a defective pixel and pixels disposed adjacent to the defective pixel to isolate the defective pixel from the initialization voltage line.
