Abstract
Provided are a touch sensitive element and a display device including the same. According to the exemplary embodiment of the present disclosure, a touch sensitive element, includes: an electroactive layer which is formed of electroactive polymer (EAP); an electrode which is disposed on at least one surface of the electroactive layer; and a hard coating layer which is disposed on the electroactive layer and the electrode and has a negative coefficient of thermal expansion (CTE). Therefore, vibration effect in a vertical direction is maximized and impact resistance may be improved.
