Abstract: Provided are a touch sensitive element and a display device including the same. The touch sensitive element according to an exemplary aspect of the present disclosure includes an electroactive layer formed of a linear boron nitride polymer and an electrode disposed on at least one surface of the electroactive layer. Therefore, a piezoelectricity of the electroactive layer is improved to improve vibration strength of the touch sensitive element and significantly improve heat resistance.
