ABSTRACT:
An electric type paper display having memory properties, rapid response times and multi-optical optical property display with an image of high quality is made. Each display element is wholly in contact with liquid in a cavity and the surface of each display element has a portion with a most positive charge. When an electrical field is applied from the outside, each display element is turned correspondingly to the direction of the electric field and, then electrically migrated through the liquid and attached to the inner surface of the cavity. Among multiple display surfaces of each display element an optical property is selected according to an image signal and is visible through a transparent support to an observer. Afterwards, the attached state of each display element, i.e., its display state is held by the action of an attraction force such as van der Waals force and electrostatic force acting between the circumferential surface of the display element and the inner surface of the cavity, even after the electric field is removed.
