Abstract
A double-face display device is formed of a substrate sheet having a first surface and a second surface, a first display medium disposed over the first surface, a second display medium disposed over the second surface, and a first display electrode and a second display electrode disposed in association with the first display medium and the second display medium, respectively. A first switching device and a second switching device are electrically connected to the first display electrode and the second display electrode, respectively, so that voltages are applied to the first and second display electrodes via the first and second switching devices, respectively, thereby driving the first and second display media to display data on both faces of the display device. The production of the double-face display device is rationalized by disposing the first and second switching devices on a common surface within the display device. The common surface may be given by one of the first and second surfaces of the substrate sheet or an inter-layer surface between layer sheets forming the substrate sheet in a laminated form.
