PURPOSE:To prevent the decrease in the quality of a display even after long- term use by providing an electrochromic layer on a transparent conductive film consisting of a plastic film as a substrate. CONSTITUTION:A film 1 produced by coating an indium tin oxide 2 on polyester is used as a transparent plastic film, and an electrochromic (EC) layer 3 is formed by sputtering of WO2 thereon, whereby an EC electrode is formed. An aq. 1N H2SO4 is used for an electrolyte, and a mixture of WO3 and carbon powder mixed with a resin is used for a counter electrode 6. A background plate 5 and a counter electrode support 7 are added to these to provide an EC display device. Any transparent org. polymer films of polyimide and polyamide imide in addition to the above are usable as the film. It is equally well to form the EC layer by sputtering of MoO3. |
