Abstract
Provided are a touch sensitive device and a display device including the same. The touch sensitive device includes: a first electroactive layer formed of a ferroelectric polymer; a plurality of electrodes disposed on at least one surface of the first electroactive layer; and a second electroactive layer in contact with the plurality of electrodes and the first electroactive layer and formed of an electroactive polymer. A coating layer having a low refractive index and formed of an electroactive polymer is formed on the first electroactive layer formed of a ferroelectric polymer having a low light transmittance, and, thus, a vibration level and a light transmittance of the touch sensitive device can be improved simultaneously.
