Electrochromic display device
First Claim
1. An electrochromic display device which comprises:
- a display electrode comprising a transparent first substrate which has an inner surface, a transparent electrode formed on said inner surface of said transparent first substrate, and an electrochromic material layer for display made of tungsten oxide and formed on said transparent electrode;
a counter electrode comprising a second substrate which has an inner surface that faces said inner surface of said transparent first substrate, a conductive layer formed on said inner surface of said second substrate, and an activated carbon fiber cloth bonded to said conductive layer with a conductive adhesive; and
a spacer means provided between said display electrode and said counter electrode so as to define an electrolyte chamber, which is filled with an electrolyte comprising LiClO4 dissolved in propylene carbonate and containing water and an acid.

Abstract
An electrochromic display device which comprises a display electrode comprising a transparent substrate, a transparent electrode formed on an inner surface of the transparent substrate and an electrochromic material layer for display made of tungstgen oxide and formed on the transparent electrode; a counter electrode comprising a substrate, a conductive layer formed on an inner surface of the substrate and an activated carbon fiber cloth bonded to the conductive layer with a conductive adhesive; and a spacer provided beween the display electrode and the counter electrode with their inner surfaces facing to each other to define, between them, an electrolyte chamber, which is filled with an electrolyte comprising LiClO4 dissolved in propylene carbonate containing water and an acid, which device has an increased original injected charge and good maintenance of the injected charge after prolonged storage.
