    Abstract: A display device includes a substrate including a bending area located between a first area and a second area. The substrate is bent in relation to a bending axis. A first wiring unit including a plurality of first wirings is arranged on the substrate to sequentially extend over the first area, the bending area, and the second area. First central axes included in each of the plurality of first wirings are spaced apart from each other by a first pitch in the bending area. A second wiring unit including a plurality of second wirings is arranged on the substrate to sequentially extend over the first area, the bending area, and the second area. Second central axes included in each of the plurality of second wirings are spaced apart from each other by a second pitch greater than the first pitch in the bending area.
