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.
