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.

Abstract: Provided is an organic light emitting display module including an active area, a pad area, and a boundary area between the active area and the pad area. Unlike the active area and the pad area, since the boundary area does not include an inorganic layer, less stress is applied to the boundary area when the boundary area is bent. Display panel pads and touch sensing member pads are disposed at the same height without having a height difference therebetween. Thus, a dummy pad may be added to remove the height difference between the display panel pads and the touch sensing member pads.

Abstract: A display apparatus including an organic light-emitting display panel and a touch sensing unit disposed on the organic light-emitting display panel is disclosed. The touch sensing unit includes a touch electrode and a wiring part connected to the touch electrode. The wiring part of the touch sensing unit passes a protruding member disposed on a non-display region of the organic light-emitting display panel, and forms a first wiring part which does not overlap the protruding member, a second wiring part overlapping the protruding part, and a connection wiring part disposed between the first and second wiring parts and having a wiring width less than the first and second wiring parts so as to overlap an edge of the protruding member.
