Abstract
An electrostatically driven electromechanical display device is disclosed. It comprises first electrode means having a reflective face of first reflectivity and second electrode means having a reflective face of second reflectivity, that second reflectivity being different from the first reflectivity. A flexible conductive tongue is disposed between the first and second electrode means. First support means supports the first electrode means with its face in facing spaced relationship to the face of the second electrode means. Second support means supports the tongue between the facing portions of the first and second electrode means in a position where the tongue may be caused to bear against the face of the first electrode means and where the tongue is in contact with the first electrode means and the second electrode means.
