Touch sensitive element and display device comprising the same

A touch sensitive element, comprising:

• an electroactive layer which is formed of a first electroactive film, a second electroactive film, and a third electroactive film disposed between the first electroactive film and the second electroactive film and is in contact with the first electroactive film and the second electroactive film;
• and
• a plurality of electrodes disposed on at least one surface of the electroactive layer,
• wherein a resonance frequency of the third electroactive film is different from resonance frequencies of the first electroactive film and the second electroactive film.

A display device, comprising:

• a display panel;
• a cover disposed above the display panel;
• and
• a touch sensitive element disposed below the cover,
• wherein the touch sensitive element includes:
• an electroactive layer including a plurality of electroactive films, the plurality of electroactive films comprising a first electroactive film, a second electroactive film, and one or more intermediate electroactive films between the first electroactive film and the second electroactive film, wherein each of the one or more intermediate electroactive films is in contact with two of the plurality of electroactive films;
• and
• a plurality of electrodes apart from each other and disposed on at least one surface of the electroactive layer, and
• wherein a modulus of each of the one or more intermediate electroactive films is larger or smaller than moduli of the first electroactive film and the second electroactive film.
