Manufacture of electrochromic display element

Abstract

Abstract PURPOSE:To obtain an electrochromic display element superior in responsiveness, stability, etc., by causing electrolytic oxidation polymn. of a polymerizable monomer in the presence of an electrochromic material having a negative electrostatic charge to form a conductive polymer film on an electrode. CONSTITUTION:An intended electrochromic display element is obtained by executing electrolytic oxidation polymn. of a heterocyclic monomer, such as pyrrole or thiophene, capable of forming a conductive polymer having a positive charge in this electrolytic oxidation polymn. in an electrolytic soln. contg. this monomer and an electrochromic material having negative charge, such as sodium bathophenanthroline-sulfonate-iron complex or phthalocyanine, using an electrolytic device composed of an anode 1 and a cathode 3, forming a conductive polymer on the anode 1, and allowing this film 2 to capture the electrochromic material.
