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.
