For example, a transparent conductive film 2, 2' such as an ITO film or a Nesa film is placed on two sheets of glass 1.11 with a thickness of 2 by a normal method such as sputtering or CVD, and the film is separated by 151 cm from each edge of the glass sheet. Formed on the entire surface, and on one side of the transparent conductive film 2, a reducing color is formed]l! The iC layer 3 is made of WO, and the other transparent conductive film 21 is formed with the chemical formula Fe4"[Fe" (O
N)*)s Surface: A Prussian blue film was coated by electrolytic synthesis, masking the periphery of each film.

Next, these plate glasses 1.1° were sealed with a sealing material 4 with an interval of 1°, and Li (3tO4
A propylene carbonate solution containing 1 mole of was injected to produce light control glass 6. In this case, when both the WO film and the Prussian blue film are coated, both EC layers are electrochemically in an oxidized state, and the WO8 film is colorless.

The EC light control glass 6 thus obtained is connected to a DC power source,
When connected to a control power supply 7 consisting of a polarity switch, etc., and applying +1V DC voltage between the transparent conductive film 2 and the transparent conductive film 2', the WO, film, and Prussian blue film became uniform over the entire surface in about 30 seconds. It was clearly colored blue, and the visible light transmittance of the light control glass was 5%.
