    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.

    Abstract: Provided is a display device (100). The display device includes a display panel (110), a contact sensitive device (120) on the display panel, and a linear polarizer (130) on the contact sensitive device. The contact sensitive device (120) includes an electro-active layer (122) which may be uniaxially elongated and configured to retard a phase of incident light. Since the display device (100) includes the contact sensitive device (120) having the electro-active layer (122) configured to retard the phase of the incident light, a separate phase retardation film for suppressing external light reflection may be omitted. As a result, the thickness of the display device (100) may be decreased and manufacturing cost of the display device (100) may be reduced.
