Abstract

PURPOSE: To prevent short-circuiting between electrodes and a counter electrode by etching away the transparent electrode members under the pinholes existing in the insulation film of an electrochromic (EC) display body of solid state type then depositing EC members and a metal thin film.
CONSTITUTION: Display pattern electrodes 12 are formed on the transparent substrate 20 of a solid state type EC display body, after which a transparent insulation film 22 is formed. The portions of the electrodes 21 under the pihholes penetrated down to the electrodes 21 existing in the film 22 are etched by a method of etching with an etchant such as heated HCl or a method such as the one of dipping the substrate 20 in a weak acidic solution and electrolyzing the same, whereby they are removed to a diameter larger than the pinhole diameter. Next, EC members (WO3 etc.) are evaporated on the film 22 to form an EC film, after which a metal thin film 24 of Au or the like is formed as a counter electrode 24. At this time, the member Au of the film 24 enters the pinholes to form a bridge 25, but a spacing 26 is produced between the same and the transparent electrode 21, so that the electrical shorting between the electrode 21 and the electrode 24 is obviated. In this way, the good display is obtained.
