ABSTRACT:
An electrochromic display cell includes front and rear glass substrates, a liquid electrolyte disposed between the substrates, and a porous ceramic plate disposed in the liquid electrolyte for providing a white display background. Transparent electrodes are formed on the front glass substrate, and electrochromic display segments are formed on each of the transparent electrodes. The transparent electrodes are formed so as to cover the substantially entire display surface of the electrochromic display cell, and electrically separated from each other by a thin gap. The operator observes the porous ceramic plate through the transparent electrodes over the entire display surface, whereby a uniform white background is provided over the entire display surface.
