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.
