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.

Abstract: A thin and lightweight display device is disclosed. An organic light-emitting display device having a touch sensor is configured such that an outer planarization layer fills a space between a plurality of dams, thereby preventing a short circuit between routing lines in the space between the dams, and such that touch electrodes are disposed on an encapsulation structure for encapsulating a light-emitting element, with the result that an additional bonding process is not required, whereby the process is simplified and cost is reduced.

Abstract: Disclosed is a display device having touch sensors which may improve visibility. In the display device, the touch sensors having a multilayer structure including a blackened layer are arranged on an encapsulation assembly arranged to cover light emitting elements, and touch pads having a multilayer structure including a partially transparent conductive layer are arranged on a region of a substrate exposed by the encapsulation assembly. Therefore, the blackened layer may prevent reflection of external light and thus visibility may be improved, and the partially transparent conductive layer may lower sheet resistance of the touch pads and thus contact resistance between the touch pads and a driver integrated circuit may be reduced.

Abstract: A display panel comprises a substrate including a plurality of polymer layers, an inorganic interlayer insulating film, and a semiconductor layer between the plurality of polymer layers and a panel array over the substrate. The semiconductor layer within a substrate may ground electric charges entered from the outside through the semiconductor layer. Thus, the display panel protects an array provided on the substrate and improves the reliability of the display device.
