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.
