Abstract

PURPOSE: To obtain the electrochromic display device (ECD) of a long life by using aluminum metal as a current collector for a counter pole.
CONSTITUTION: The current collector 6 composed of aluminum metal is enclosed by the mixture of tungsten trioxide reductant or iron berlinate reductant, electric conductor and binder. This is pressure-molded to form a counter pole 5. Next, a reflecting plate 10 and electrolyte 12 are snadwiched by way of a spacer 9 between the transparent substrate 1 provided with transparent electrodes 2 and display pole (formed by transition metal oxides of WO3, etc.) 3 and the back substrate 8 provided with the counter pole 5 disposed with the aforementioned aluminum current collector 6, whereby the ECD is formed. It is desirable to use the expanded net of aluminum for the above current collector 6.
