Abstract
Provided is a touch screen for generating a haptic sense that may minimize a structure added for haptic generation by simultaneously employing a single electrode layer that constitutes an existing touch panel as an electrode layer for transferring the haptic sense. A touch screen for generating a haptic sense according to an exemplary embodiment of the present disclosure includes a touch panel including at least one substrate, each formed with at least one electrode, and an additional electrode to generate the haptic sense on a portion touched on the touch panel using an electrostatic force that occurs between the additional electrode and a predetermined electrode among the at least one electrode.
