PURPOSE:To obtain a thin film type solid ECD device undergoing little aging change and having a high responding speed by forming a laminated structure consisting of an electrochromic film and a solid electrolyte film made of an amorphous lithium compound. CONSTITUTION:A laminated structure consisting of an electrochromic film 11 and a solid electrolyte film 12 made of an amorphous lithium compound is formed. The structure is interposed between an upper electrode 13 and a lower electrode 14 and supported on a substrate 15. Amorphous lithium niobate, lithium tantalate, lithium vanadate, lithium titanate, lithium zirconate, lithium hafnate or the like is used as said amorphous lithium compound. The electrochromic film 11 is a thin metallic oxide film of tungsten oxide, molybdenum oxide, nickel oxide, iridium oxide or the like. |
