ABSTRACT:
In an electrochromic display device having a plural number of indication electrodes displaying an information by repetition of coloring mode and discoloring mode, both modes of the indication electrodes being caused by an electrochemical oxidation-reduction reaction at the indication electrodes, and having an auxiliary electrode and counter-electrode to the indication electrodes and to the auxiliary electrode, the improvement is that an auxiliary electrode is further provided so as to act as the same acting mode as that of at least one of the indication electrodes, thereby removing an irregularity of color density of displaying at the acting indication electrodes.
