Abstract
A display device may include a switching device, a gate line, a data line, a pixel electrode, and an auxiliary line. The switching device includes a first electrode, a second electrode, and a third electrode. The gate line is electrically connected to the first electrode. The data line crosses the gate line in a plan view of the display device and is electrically connected to the second electrode. The pixel electrode is electrically connected to the third electrode. The auxiliary line is electrically connected through the first gate line to the first electrode and crosses the gate line in the plan view of the display device.
