An electrochromic display device having transparent electrodes on a substrate and coated with electrochromic material for selectively displaying optical patterns, a counter-electrode on a parallel substrate also coated with electrochromic material, a thin porous separator membrane for closely spacing the substrates, the separator pores saturated with liquid electrolyte contacting the electrochromic layers and pigment providing a contrasting background for the first mentioned electrochromic layer and hiding the second electrochromic layer. |
