Abstract

PURPOSE: To achieve the longer life of the display device by using the iron compound which is insoluble in electrolyte as the reversible oxidation reaction material of the counter electrode of the electrochromic display device.
CONSTITUTION: In the electrochromic device formed by opposing the transparent substrate 1 provided with thin-film transparent electrodes 2 composed of display electrodes 2' and lead electrodes 2" and the back substrate 3 provided with a counter electrode 4 by way of a spacer 5 and sealing electrolyte (e.g., an aqueous solution of di-n-octyl, 4, 4'-dipyridinium chloride and potassium chloride) 9 together with separators 7 therebetween; the one comprising the iron compound which is insoluble in the abovementioned electrolyte (e.g., iron berlinate), graphite and polyethylene powder to the abovementioned electrolyte at weight ratios of about 10:5:2, hot- press-molding the mixture then electrolytically reducing the same in an aqueous potassium chloride solution is used as the abovementioned counter electrode 4.
