The lead wire a 1 of No. 1 is connected to the electrode group α by an external circuit (not shown), and the electrode group α is set to 0 potential, the electrode group β to potential V - , and the electrode group γ to potential V + . At this electric field distribution, M stored in segment electrode α1 as MWO3 due to the previous operation becomes a cation.
It becomes M + and moves to segment electrode β 1 , and electrode β 1 is colored. This is a driving method that uses reactions between display electrodes. Therefore, a counter electrode is not required. At this time, anion e - is liberated from segment electrode β 1 and transferred to other segment electrodes α 1 , γ 1
However, since the anion e - does not directly contribute to the coloring mechanism, the electrodes α 1 and γ 1 are not colored. Moreover, at this time, the segment electrodes β 2 , β 3 ,
Since β 4 also has a negative potential, it tries to attract cations M + , but in the initial state described above, most of the cations M + are concentrated on segment electrode α 1 . , there are very few cations M + in the other segment electrodes, and the cations M + released from segment electrode α 1 move to the right from segment electrode γ 1 due to the potential wall caused by segment electrode γ 1 . Can not do it. Therefore, segment electrodes β 2 , β 3 , β 4 are not colored, and only segment electrode β 1 is strongly colored.

If the potential of the electrode group α is set to V − , the potential of the electrode group α is set to V + , and the potential of the electrode group β is set to 0, the segment electrode β 1 is decolored and the segment electrode γ 1 is colored by the same mechanism as described above.
これを繰返して着色状態にある１個のセグメン
ト電極を順次右へ移動させることができる。 By repeating this process, one colored segment electrode can be successively moved to the right.
また電極群α，β，γの電位関係を逆にすれば
左へ移動させることも可能である。 Furthermore, by reversing the potential relationship between the electrode groups α, β, and γ, it is also possible to move them to the left.

できる。 And finally, the colored segment is the rightmost electrode γ 4
After reaching the voltage, the potential relationship is returned to the initial state shown in FIG. 3a. At this potential, segment electrode α 1
Only the electrode α 1 is colored, since only the electrode α 1 is set to the potential V − . Thereafter, the colored point can be moved in the same manner as described above by applying the potentials shown in FIGS. 3b and 3c.

It consists of 60 segment electrodes. The outer segment electrodes are driven such that every minute the colored segment electrode is transferred to the adjacent electrode.
