    • A process for forming an electrochromic film to be used in an electrochromic device is provided. The process includes a step of introducing a mixture of oxygen gas and inert gas at a predetermined mixing ratio into a reactor in which is provided an electrode having thereon a sheet of tungsten as a target and a counter-electrode holding thereon a substrate under a predetermined total pressure condition and a step of applying a predetermined voltage between said electrodes while maintaining the substrate at a predetermined temperature. The present process allows to provide a WO.sub.3 -sputtered film on the substrate. The present invention also provides an electrochromic display device in which the electrochromic film is operated under control not to reach the color saturation condition, thereby preventing the occurrence of separation of the film and thus ensuring a long-term servicelife.
    • 提供一种用于形成用于电致变色装置中的电致变色膜的方法。 该方法包括以预定的混合比将氧气和惰性气体的混合物引入反应器中的步骤,在该反应器中设置有在其上具有钨片作为靶的电极和在其上保持预定的基板的对置电极 总压力条件和在所述电极之间施加预定电压同时将衬底保持在预定温度的步骤。 本方法允许在衬底上提供WO3溅射膜。 本发明还提供一种电致变色显示装置,其中电致变色膜在控制下操作不达到色饱和状态,从而防止膜分离的发生,从而确保长期的服务。
