Electrochromic display element

Abstract

Abstract PURPOSE:To obtain an all solid state type ECD which is unaffected by atmospheric humidity, is usable in a vacuum as well and has high wet durability by sealing films with covering resins using a xylene polymer for a lower layer and a reaction curing type resin for an upper layer. CONSTITUTION:An electrode layer 2 is provided on a glass substrate 1, and a reversible electrolytically oxidizable thin film 3 of iridium hydroxide, ruthenium hydroxide, rhodium hydroxide, etc. is provided thereon. Thereafter, an insulating thin film 4 of Ta2O5, Nb2O5, ZrO2, etc. is laminated on the film 3, and WO3 or MoO3, etc. are laminated as an electrolytically reducing thin film 5 on said thin film 4. About 10-30vol.% water is contained in said WO3 or MoO3. The film 3 and the film 5 may be alternated with each other. A counter electrode 6 is provided on the film 5. The entire part of the five layers is first covered with a xylene polymer 7 and is then covered with a reaction curing type resin 8 such as an epoxy resin, and a protecting plate 9 is adhered thereto.
