Abstract: Embodiments of the disclosure relate to touch display devices. A shielding pattern to which a constant voltage is applied is placed between the touch routing line and the encapsulation part without overlapping the touch routing line. Thus, it is possible to block the noise due to the signal line positioned under the encapsulation part by the electric field generated by the shielding pattern. Further, the metal disposed on the same layer as the shielding pattern in the planarized area of the encapsulation part may be used as a touch routing line, reducing the resistance and width of the touch routing line and hence the planarized area of the encapsulation part. Thus, it is possible to provide a touch display device for which an increase in the non-active area has been reduced and display noise has been reduced upon touch sensing.

Abstract: Provided is a touch display device. Because a shielding electrode, which is disposed in a non-active area and electrically coupled between a common electrode and a common voltage supply line, is located between a touch routing line and a signal line, the effects of noise caused by the signal line on the touch routing line may be reduced. Further, an encapsulation portion located on the shielding electrode has a planarized structure. The resulting maintenance of a certain distance between the shielding electrode and the touch routing line may reduce noise caused by the signal line from indirectly affecting the touch routing line through the shielding electrode.
