Abstract
A touch sensitive device, a display device including the touch sensitive device and a method of driving the same are discussed. The touch sensitive device can include an electroactive layer including an electroactive polymer; and one or more first electrodes and one or more second electrodes are disposed on only one surface of the electroactive layer, in which the first and the second electrodes include a conductive material. The first and the second electrodes of the touch sensitive device can be disposed only on one surface of the electroactive layer, a driving voltage of the touch sensitive device can be reduced and transmissivity can be improved.
