A vibration touch sensor includes; a first substrate, a second substrate arranged to face the first substrate with a predetermined gap therebetween, a first electrode disposed on the first substrate, a second electrode disposed on the second substrate, a piezoelectric material layer disposed on one of the first electrode and the second electrode, wherein the piezoelectric material layer generates an electrical signal in response to an external touch applied to at least one of the first substrate and the second substrate, and a controller which receives the electrical signal generated from the piezoelectric material layer and generates a touch input signal, the controller controlling an alternating current voltage applied to at least one of the first electrode and the second electrode.
