RD-13,518 METHOD FOR FABRICATION OF ELECTROSCOPIC DISPLAY DEVICES AND TRANSMISSIVE DISPLAY DEVICES FABRICATED THEREBY ABSTRACT OF THE DISCLOSURE An electroscopic display device includes a plurality of small movable electrode plates which are each electrostatically deflectable from a resting position at a rear surface of a display call to a display position adjacent to a viewable front surface of the cell. A portion of an 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 movable electrode plate 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 movable electrode, spring and fixed electrode as an integrated structure.
