摘要： A display device includes a first substrate, a second substrate, a gate line, a data line, a link line, a driving integrated circuit, a repair line, and a dummy line. The second substrate is spaced apart from the first substrate. The gate line is on the first substrate. The data line is on the first substrate. The link line is connected to one of the gate line and the data line. The driving integrated circuit is connected to the link line. The repair line is in a non-display area of the first substrate. The repair line overlaps, in the non-display area, the link line and the one of the gate line and the data line. The dummy line overlaps the repair line. Shapes of the dummy line and the repair line are substantially equivalent.
