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.

Abstract: A display apparatus includes a substrate having a display area with a display device to display an image, and a non-display area around the display area. The non-display area has a bending area bent about a bending axis. An encapsulation layer is located over the display area. A touchscreen layer is located over the encapsulation layer and includes a touch electrode. A touch wire is connected to the touch electrode, and extends from an upper portion of the encapsulation layer, and at least partially into the bending area. A fan-out wire configured to apply an electric signal to the display area and is at least partially disposed in the bending area. The touch wire and the fan-out wire are on different layers from each other in the bending area.
