Abstract: A touch display device includes a touch planarization film. The touch planarization film may be disposed on an inclined portion of an encapsulation layer in a non-active area of a display panel, and a touch routing line may be disposed on the planarized area of the touch planarization film, so that it is possible to reduce parasitic capacitance between the touch routing line and a display signal line located under the encapsulation layer without increasing dimensions of the non-active area. Therefore, it is possible to easily adjust a width of the touch routing line and reduce the parasitic capacitance deviation between the touch routing lines, thereby improving the performance of the touch sensing.

Abstract: Embodiments of the present disclosure provide a touch display device. A body portion and a wing portion of a touch electrode are formed by cutting the electrode metal along the direction in which the electrode metal is arranged. The body portion, the wing portion and a dummy metal located therein are irregularly formed, so that it is possible to improve the performance of touch sensing and improve the visibility of the electrode metal. In addition, in the case of a large-area touch display device, by dividing the touch electrode line and forming a cutting pattern corresponding to the divided boundary of the touch electrode line inside the touch electrode line, it is possible to prevent the divided boundary of the touch electrode line from being recognized and reduce a load on the touch electrode line, thereby improving the performance of touch sensing.
