Abstract

A display element formed by two parallel glass plates each having opposed electrodes provided thereon and an optical medium disposed in the intermediate space therebetween, wherein a connection between at least one electrode of one plate and at least one electrode of another plate, and the interplate spacing is achieved by means of electrically conducting fibers each having the same constant diameter disposed between the plates around the periphery thereof, with the conductive fibers contacting the respective electrodes formed on the display plates and thereby electrically connecting the same. The spacing for the display element is derived by mixing the conductive fibers in an adhesive compound to form a cement ridge around the periphery of the plates and applying the compound containing the conductive fibers to at least one of the plates, and then pressing the plates together until the plates are separated by a distance corresponding to the diameter of the conductive fibers.
