ABSTRACT:
An electrochromic display device in which an electrolyte is disposed between a display electrode and a counter electrode, and an electrochromic substance layer is formed at least to the inside of said display electrode, wherein the counter electrode comprises a layer containing a white redox substance. Since the white redox substance layer is formed to the counter electrode, white background plate is no more necessary which enables to reduce the fabrication cost and give a great feasibility for the design of ECD.
