Abstract: By forming a repair structure in a horizontal direction and vertical direction by using one or more repair lines between two or more pixels adjacent to each other in a display panel, even though a dark spot appears due to a defective operation of one pixel, the one pixel may be compensated to be driven by using the other pixel.
