ELECTROCHROMIC DISPLAY ELEMENT

摘要

PURPOSE:To relieve the rising of an inner pressure of the titled element and to prevent the breakage of a substrate and the breakage of the connection between the substrate and a spacer by using an electroconductive plastic film to the electroconductive substrate of a counter electrode. CONSTITUTION:The transparent electroconductive film 1b is formed on the transparent glass plate 1a as the transparent electroconductive substrate 1 lying in the display electrode side. The insulating protective film 3 composed of silicon dioxide is formed on the transparent electroconductive film 1b except the display part. The WO3 layer is laminated on the display to form the electrochromic substance layer 2. The electroconductive plastic film in which a polyester film is as a base film 4a, and the vapor deposited film of Au is formed on the base film as the electroconductive film 4b is used as the electroconductive substrate 4 lying in the counter electrode side. The counter electrode 5 provided on the substrate 4 is formed by coating a mixture of iron tungstate and a carbon paste in the weight ratio of 2:1 on the electronductive 4b of the substrate 4 followed by heating.
