A display device according to an exemplary embodiment of the present invention includes a flexible first substrate including a display area, and a non-display area around the display area, a first piezoelectric material layer&#x2014;at one side of the first substrate, an intermediate electrode layer contacting the first piezoelectric material layer, a piezoelectric material layer driver coupled to the intermediate electrode layer, and configured to apply a driving voltage to the intermediate electrode layer to form an electric field at the first piezoelectric material layer, a thin film transistor at one side of the first substrate, and a pixel electrode connected to the thin film transistor.

Display device

Touch-related information which cannot be acquired by the naked eye (dubbed here as sub-optical pattern information) has its corresponding sub-optical patterns respectively positioned within the aperture areas of respective domains such that the displayed image, as viewed from different viewing angles is not adversely affected by the embedded sub-optical patterns. One type of touch-related information which can be conveyed is that of touch location of a sub-optical pattern sensing pen positioned over one or more of the sub-optical patterns.

A panel for a display device is provided. The panel includes a first substrate, a touch sensing circuit formed on the first substrate, the touch sensing circuit including at least one sensing thin film transistor and a connection wire, and a shielding electrode formed covering at least a portion of the sensing thin film transistor and the connection wire.
