PURPOSE:To produce a titled EC display which is fast in response, permits multi- color display, has high resistance to environment and has a long life by using prescribed polymer films in forming the constituting layers of the display except the transparent electrode, display electrode and counter electrode thereof. CONSTITUTION:A colored active material layer is formed of the film of a polymer (e.g.; acrylic resin, fluororesin) containing (A) an organic EC material (e.g.; viologen, diphthalocyanine), (B) an ion donating and accepting material (e.g; lead halide, pyridine halide) and (C) a plasticizer (e.g.; dioctyl phthalate) incorporated therein. More specifically a transparent display electrode (e.g.; tin oxide film) 2 is provided on a transparent substrate (e.g.; glass plate) 1 and further the above-described colored active material layer 7 and counter electrode 5 are provided thereon, whereby the EC display is produced (a symbol 6 is a sealing layer using an epoxy resin or the like). Since the above-mentioned display has the colored active material layer wherein the plasticizer is present, the device has a particularly high rate of response. |
