A display device includes a display panel and a data driver. The display panel includes at least one gate line, at least two data lines, a display area including a pixel connected to the at least one gate line and the at least two data lines, and a peripheral area outside the display area, the peripheral area including a pair of fan-out wiring structures. The data driver is configured to apply data voltage to the at least two data lines. Each of the pair of fan-out wiring structures includes a bent structure, the bent structure of one of the pair of fan-out wiring structures includes the same material as the at least one gate line, and the bent structure of the remaining one of the pair of fan-out wiring structures includes the same material as the at least two data lines.
