Abstract: A display apparatus having a connection electrode which crosses a bending area may be provided. The connection electrode may be disposed on a device substrate including a bending area between a display area and a pad area. The connection electrode may connect the display area and the pad area across the bending area. The connection electrode may have a stacked structure of the lower connecting electrode and the upper connecting electrode. A light-emitting device, an encapsulating element and a touch electrode may be sequentially stacked on the display area of the device substrate. The upper connecting electrode may include the same material as the touch electrode. Thus, in the display apparatus, the disconnection of the connection electrode due to bending stress and external impact may be reduced.

Abstract: Disclosed is a display device capable of reducing the thickness and the weigh thereof. A display device having a touch sensor realizes electrical connection of a routing line and a touch pad via an auxiliary conductive layer, which is connected to the routing line under an encapsulation unit, even if a disconnection fault occurs in the routing line, thereby achieving increased yield and reliability. In addition, through the provision of a touch sensor disposed above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.
