ABSTRACT:
An electrochromic display device comprising two electrode substrates, at least one of which is transparent is prepared by applying a solution containing one or more transition metal compounds under an inert atmosphere to the surface of at least one of said electrode substrates. Then, the solution is dried so as to form an electrochromic layer on the surface of the electrode substrate. The drying is carried out by using a temperature ranging between room temperature and 120.degree. C. Finally, the two electrode substrates are fixed in a manner to face each other with an ionic conductor layer or electrolyte layer disposed therebetween to obtain the electrochromic display device.
