Abstract
Electrochromic display devices which will maintain coloration after the electric current has been removed will comprise an electronic conductor consisting of a support which may be electrically conductive per se or contain an electronic conductor thereon, an electrochromic material in contact with said conductor, a solid electrolyte comprising a blend of an organic polymer and a heteropoly acid or salt thereof disposed on said electrochromic material and a counter-electrode in contact with the solid electrolyte. By utilizing this type of solid electrolyte, it is possible to obtain a display device which may range from about 5 to about 100 microns in thickness.
