Abstract
A cell illuminated by a light source is constituted by an electrolyte containing metallic ions and interposed between a first wall coated with a first transparent conductive film which forms a display electrode and a second wall coated with a second conductive film which forms a counter-electrode. Deposition or dissolution of an absorbent metallic thin film less than 10 nm in thickness is carried out on the display electrode by electrochemical reaction.
