    • PURPOSE:To provide stabilized counter electrode potential and a long life and to enable maintenance of specified coloring density of a display electrode by using an aq. soln. contg. chlorine ion having specific pH for the electrolyte and using a silver/silver chloride electrode for the counter electrode. CONSTITUTION:A counter electrode substrate 1 consists of transparent conductive glass formed with a conductive film 1b consisting of indium oxide on a transparent glass plate 1a and a silver layer 2 is formed on a conductive film 1b. A display electrode substrate 3 consists similarly of a transparent conductive glass formed with a transparent conductive film 3b consisting of indium oxide on a transparent glass plate 3a on which conductive surface an electrodeposition film 4 consisting of iron hexacyanoferrate is formed. A background material 5 consisting of a porous sheet is coated with an electrolyte 7 composed of 1mol/l aq. potassium chloride soln. The pH of the electrolyte is specified to 2-10.
