Electrochromic display device |
摘要 |
An electrochromic display device comprises; an electrolyte held between two substrates at least one of which is transparent. A display electrode is formed on a surface of one substrate and has an electrochromic substance film formed thereon, the surface being in contact with the electrolyte. A first counter electrode is formed on a counter surface of the other substrate in opposed spaced-apart relationship with respect to the display electrode, and a second counter electrode is formed on a face of either one of the substrates, the face being in contact with the electrolyte. Circuitry applies a first voltage between the display electrode and the first counter electrode to effect coloration of the display electrode, and applies a second voltage between the first and second counter electrodes to establish an electric field therebetween effective to remove a negative ion region which forms in the vicinity of the first counter electrode during coloration of the display electrode.
