Abstract

PURPOSE:To simply manufacture an entirely solid electrochromic (EC) display device with high reliability at a low cost by interposing an org. solid electrolyte film between a color developing layer of a reducible EC substance and a color developing layer of an oxidizable EC substance. CONSTITUTION:Transparent electrodes 2 are formed on transparent substrats 1, the 1st color developing layer 3 of a reducible EC substance such as WO3 or a viologen polymer is laid on one of the electrodes, and the 2nd color developing layer 4 of an oxidizable EC substance such as Ir oxide is laid on the other. An org. solid electrolyte film 5 which transmits ion but does not transmit electron, e.g., a cationic conductive film of polyvinyl sulfonate or polystyrene sulfonate is interposed between both the substrates to manufacture an EC display device. Thus, the EC display device which responds quickly, can be driven at a low voltage and has a long life is obtd. by said simple manufacturing method.

ディスプレイは比較的単価が高くなると思われる。DETAILED DESCRIPTION OF THE INVENTION In a complementary electronic (electronic) solid-state display in which a first coloring layer is reduced and colored by application of a voltage, and a second coloring layer is simultaneously oxidized and colored, a blue coloring layer is used. An electric virtual AI display with an insulating layer sandwiched between the two has been reported, and is attracting attention for its fast response, low driving voltage, and long lifespan. However, in the Elect411 ivy display with this structure, when forming the topmost transparent conductive film, techniques such as ion blating are used instead of normal thin film forming techniques to prevent deterioration of the underlying coloring layer. . In general, in order to economically manufacture this type of device, it is desirable not to use a vacuum device, and it is thought that the unit price of an electric display made by the above method is relatively high.

In the case of a zero-reflection plate in which both substrates (2) are made of glass or plastic sheets such as polyester, at least one is made of glass or plastic sheets, and the other is provided with a reflector or a reflector is used as the substrate. The transparent conductive film (2) is formed on the substrate (2) using a conventional thin g formation technique. The first coloring layer (1) is made of a reducing electrolyte material and is formed into a desired shape on the patterned transparent conductive film. The second color-forming layer ■ is made of a material that turns into a chemical substance, and when the display is completed, #
It is formed in such a shape that it vertically overlaps or overlaps the coloring layer 11. Reducing Electoric W4 substances include tungsten oxide and molybdenum oxide.

Iridium oxide, nickel fluoride, tetrathiafulvalene polymer, lanthanide shifta-cyan complex, etc. can be selected as the material. The organic solid electrolyte film is made of sulfonic acid type 01 polyvinyl. Sulfonic acid, meristyrene sulfonic acid, bo-92-acrylamido-2-methylpropanesulfonic acid, IafiOn, or other cationic conductive films or other ionically conductive films may be selected. These materials have the property of allowing ions to pass through, but not electrons. In order to improve the contact between the organic solid electrolyte and the coloring layer, a thin layer of organic material may be provided on the surface of the coloring layer.

い。A feature of the electric chromic display of the present invention is that it is extremely easy to manufacture because it has a structure in which an organic solid electrolyte film is sandwiched between two substrates. Furthermore, unlike the method of accumulating films one after another, there is no deterioration of the underlying film as the upper film is formed, so it is highly reliable.
