Abstract: Embodiments of the disclosure relate to touch display devices. The difference in parasitic capacitance due to the difference in length between the touch routing lines may be reduced by separately arranging touch electrode lines in the active area and connecting the touch routing line connected with each portion of a touch electrode line with the touch routing line connected with each portion of another touch electrode line. Therefore, it is possible to reduce loads and the differences in touch sensing depending on the connection structure and position of the touch routing line by driving the touch electrode line in a double-routing structure. By so doing, the performance of touch sensing may be enhanced.

Abstract: Provided is a touch display device including a folding area in an active area. The same pattern of touch electrodes can be maintained in both a reference area and a folding area and cracks on touch electrodes in the folding area, by applying a pattern structure of a touch insulation film disposed in the folding area. Therefore, the degradation of touch sensing performance, caused by cracks on the touch electrodes in the folding area, can be prevented and touch sensing sensitivity can be uniform in the reference area and the folding area, thereby improving touch sensing performance of the touch display device including the folding area.
