CONSTITUTION: An ECM soln. (electrochromic soln.) is prepd. and is applied on the electrochromic layer to about a film layer of 0.2 to 0.4μm by a method such as spin coating and further, the coating layer is subjected to a heat treatment, by which the ECM layer 3 is formed as a stable film. A supporting electrolyte consisting of LiBF4 is used as a solid phase electrolyte(SPE) 2 of a polyethylene oxide-alkaline metal system for this layer. Further, The SPE 2 is injected into the film layer 1 and the ECM layer 3 and after these layers are sealed by a heat sealing iron, etc., the layers are solidified by irradiation with UV rays, by which the display tape A is obtd. The tape A is stuck to the front surface of a plug 6a of the plug 6a and adapter 6b connected at one end to cables 7, 8.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the current-carrying display tape according to the present invention, which will be specifically described below with reference to the drawings.

[0007] 1 is a film layer with a transparent conductive film, 2
Is a solid electrolyte layer (SPE).
Has a high ionic conductor such as polyethylene oxide (PEO) and antimonic acid, and as a supporting electrolyte,
LiBF ₄ (lithium tetrafluoroborate) is used.

3 is an electrochromic layer (ECM
Layer). A transparent conductive layer 4 is formed on the electrode side with a thin film of a paint made of powder such as indium tin oxide (ITO) or tin dioxide (SnO ₂ ) and provided with a display surface.

The solution for forming the ECM layer 3 is a powder of metallic tungsten (purity 3N) and hydrogen peroxide (H ₂ O ₂ ).
Add. Then, a vigorous dissolution reaction occurs and a strongly acidic solution is obtained.

Put a platinum net with platinum black into this solution,
Platinum catalyst decomposes and removes excess hydrogen peroxide, 9
After about 0 minutes, for example, use a rotary evaporator to dry it to 40 ° C or below, and then, over 90 minutes, peroxidized polytungstic acid (2WO ₃ · H ₂ O ₂ · NH ₂ O) is formed, which is a pale yellow color. The powder of

Next, deionized water having a water resistance value of 10 MΩ or more is mixed with peroxidized polytungstic acid at an appropriate ratio, ultrasonic vibration is applied for 1 to 2 minutes to dissolve it, and further filtration is performed with a 0.2 μ filter. Then, a transparent polyacid aqueous solution is formed, and this becomes an ECM solution for coating.

The thickness of the ECM layer 3 is 2000 to 400.
At 0 Å (about 0.2 to 0.4 μm), for example, spin coating is applied on the film depending on the concentration of the polyacid aqueous solution and the rotation speed of the spin coater. Is applied to the PET film having the transparent conductive layer 4 by dip coating or bar coating which is pulled up by a winder or the like, and the PET film is heated at 100 to 120 ° C. for about 1 hour to be heat treated. By this heat treatment, water is evaporated and the peroxide is blown off, and a stable film is formed.

Next, in the production of an electrochromic display (ECD), an ITO (indium tin oxide) film 4 was attached to a PET film, and tungsten oxide (WO ₃ ) was applied to the film whose resistance value was as low as possible. A polyethylene oxide-alkali metal-based solid electrolyte (SPE) 2 and lithium tetrafluoroborate (LiBF ₄ ) are used, and the spacer sealing material is a polyolefin or ethylene vinyl acetate-based heating agent. Electrolyte (SPE) is injected between the films using a trowel between the heat seals (temperature 10
