Abstract: In a foldable display device, stretchability is given to an outermost area of the folding area of the first support substrate to which a relatively high stress is applied. Thus, the folding radius at the outermost area increases, which relatively reduces the stress at the outermost area. Accordingly, it is possible to suppress occurrence of cracks in the outermost area.

Abstract: The present invention relates to a touch display device, a back light unit, and a flexible printed circuit. The present invention improves a structure of a flexible printed circuit that outputs a force driving signal so as to be suitable for a structure included in the touch display device. Thus, an example of the present invention is a touch display device including a compact signal transmission path. Further, a force electrode and the flexible printed circuit are configured as one body to transmit a force driving signal to the force electrode through a signal line in the flexible printed circuit. Thus, an example of the present invention is a touch display device that can stably apply a force driving signal through a compact signal transmission path.
