    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.
