Abstract: Embodiments of the present disclosure are related to a touch display device, by implementing a touch routing line using a part of a display electrode metal disposed in a non-active area of a display panel, the non-active area is reduced, and the touch routing line can be disposed while preventing an increase of a load of the touch routing line. Furthermore, by connecting the touch routing line implemented with the display electrode metal under an encapsulation layer to a touch electrode on the encapsulation layer through a connecting metal located under a dam, the touch routing line can be disposed under the encapsulation layer without dropping a function of the encapsulation layer for reducing moisture permeation.
