Abstract
A display device includes a light guiding fixed electrode portion formed of a transparent material for guiding light incident from an exterior to the surface portion having a transparent conductive layer and then emitting the light, a flexible conductive light shielding plate arranged to face the transparent conductive layer of the light guiding fixed electrode portion and having one end fixed to pass the emitted light therethrough, and an electrostatic force generating circuit for applying a potential difference between the conductive light shielding plate and the transparent conductive layer to generate electrostatic force between the transparent conductive layer and the conductive light shielding plate, wherein the conductive light shielding plate is displaced according to the electrostatic force with one end thereof set as an axis to shield the surface portion of the light guiding fixed electrode portion when the potential difference is applied between the conductive light shielding plate and the transparent conductive layer.
