Zusammenfassung:An electroscopic display device includes a plurality of small, moveable plates which are each electrostatically deflectable from a resting position, at a rear surface of a display cell, to a display position adjacent to a viewable front surface of the cell. A portion of the electrode structure remains fixedly adjacent to the cell rear surface and a second electrode is positioned fixedly adjacent to the front surface. Light entering through the rear of the cell is internally reflected before exiting through the front surface, only if the moveable electrode portion has been electrostatically attracted to the fixed front electrode. The display device is fabricated by masking and subsequent etching of a plurality of layers formed upon the surface of a display substrate, to provide the moveable electrode, spring and fixed electrode as an integrated structure.
