Touch display device
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.
