Provided is an electroactive film comprising a polysiloxane polymer, a method of manufacturing the electroactive film, a touch sensitive device including the electroactive film, and a display device including the same. The touch sensitive device of the present disclosure includes an electroactive film including a siloxane polymer having a fluoro group or a chloro group bonded to a part of the backbone, and the dielectric constant of the electroactive film is improved by 15% or more by elongation at an elongation rate of 100% or more. The electroactive film of the present disclosure has an excellent dielectric constant and an excellent light transmittance, and thus the intensity of vibration of the touch sensitive device is improved, the driving voltage for the touch sensitive device may be lowered, and the touch sensitive device may be disposed on the display panel.
