ABSTRACT:
An electroscopic display cell in which stationary and moveable plate electrodes are fabricated upon a single substrate to provide a display with operating characteristics independent of cell thickness. The stationary electrodes are overcoated with a dielectric layer and a conductive plate electrode structure is thereafter fabricated upon the dielectric layer. Each electrode plate has a rest position determined by support members affixed to the dielectric layer and independent of the spacing between the single substrate and another substrate, which serves only to contain a display fluid.
