Abstract:
A touch sensing display device includes: a thin film transistor array panel including a thin film transistor; and an opposing display panel facing the thin film transistor array panel. The opposing display panel includes a piezoelectric sensor including a capacitive sensor and a piezoelectric layer. The capacitive sensor includes sensing wires, driving wires, and a bridge connecting the sensing wires together or the driving wires together. The piezoelectric sensor further includes a pair of electrodes, the piezoelectric layer being disposed between the pair of electrodes. The bridge and a first electrode of the pair of electrodes are formed of the same material and in the same layer.
