Abstract
Provided are a touch sensitive element and a display device. A touch sensitive element according to an exemplary embodiment includes an electroactive layer including a plurality of electroactive films formed of an electroactive polymer; and a plurality of electrodes disposed on at least one surface of the electroactive layer. In this case, the plurality of electroactive films is configured by a first electroactive film, a second electroactive film, and one or more electroactive films between the first electroactive film and the second electroactive film. A modulus of one or more electroactive films is higher or lower than both a modulus of an electroactive film which is in contact with an upper surface and a modulus of an electroactive film which is in contact with a lower surface. The touch sensitive element according to the exemplary embodiment of the present disclosure may implement a sufficient vibration strength in all frequency domains.
