れた構成になつている。 In FIGS. 1 and 2, 1 and 2 are substrates made of transparent glass. Reference numeral 3 denotes a display electrode provided on the lower surface of the transparent glass 1, on which a display pattern is formed, and is made of In 2 O 3 , SnO 2 or a mixture thereof. 4 is a pole opposite to the display pole 3 provided on the upper surface of the transparent glass 2;
After In 2 O 3 , SnO 2 or a mixture thereof is deposited on the entire surface of the substrate, a frame removed portion 4a is formed by etching it away as shown in FIG. Reference numeral 5 denotes a frame member that surrounds the display electrode 3 and the counter electrode 4 so as to face each other with a solution 6 containing an electrochromic material interposed therebetween, and is provided with an injection port 5a so that the solution 6 can be injected later. There is. 7 is a sealing material for sealing the solution 6 after it has been injected, and is made of solder or the like. In this case, although the method of drawing out the electrodes is not shown, the display electrode 3 and the counter electrode 4 are provided with an electrode drawing part that extends to the outside of the frame member 5 in order to connect with the lead wire, and this electrode drawing part is insulated from the frame member 5 by a well-known means such as an insulating film.
