Abstract
To provide a display device and the like capable of assisting operations by effectively presenting a sense of texture to the skin of human beings while suppressing generation of unpleasant noises. The display device includes: a visual sense display unit which displays an operation screen to be a target of touch operations done by a user by image signals supplied from outside; and a plate-type tactual sense presenting unit which is disposed on the upper side of the visual sense display unit and presents a tactual sense that can be perceived by the user on the operation screen. The tactual sense presenting unit includes X-electrodes and Y-electrodes which exhibit transparency for visible light rays and operate by voltage signals supplied from outside, and a resin exhibiting transparency for visible light rays is filled in a layered-state gap between the visual sense display unit and the tactual sense presenting unit.
