Abstract
An electronic apparatus includes an electrode substrate that has a transparent first electrode and a transparent second electrode that are provided on one surface of a transparent insulating substrate, and an insulating film that electrically insulates the first electrode from the second electrode, the electrode substrate being configured so as to cover a surface of a display medium where an image is displayed; and a driver circuit that is connected to the electrode substrate and generates an electric field between the first electrode and the second electrode by applying a voltage to the first electrode and the second electrode.
