阅读:474发布:2021-11-12

专利汇可以提供Electrochromic display device专利检索,专利查询,专利分析的服务。并且PURPOSE: To enhance the electrochemical stability of a display electrode and obtain an electrochromic (EC) device having a long life by placing an EC substance on a light-transmissive electrically-conductive film with a light-transmissive metal thin film in-between to form the display electrode.
CONSTITUTION: Light-transmissive electrically-conductive film 22 made of In
2 O
3 , SnO
2 or the like is laid on light-transmissive substrate 21 such as glass plate or plastic plate, and film 22 is covered with a metal such as Au, Ru, Rh or Pt by an electron beam vacuum-deposition method to form light-transmissive metal thin film 24. Layer 23 of an EC substance such as WO
3 or MoO
3 is then formed on film 24 in the form of a desired pattern, and an electrolyte is filled between the resulting display electrode and an opposite electrode to obtain an EC device. By adjusting the thickness of film 24 to above 10Å a light transmittance of about 80% or more can be maintained.
