PURPOSE:To obtain an electrochromic display device of a low cost and high stability by coating a film formable compound on a substrate, forming the film by baking, and inserting a material imparting electric conductivity into electrodes. CONSTITUTION:A transparent electrode 16 consisting of tin oxide or the like is vapor-deposited on a transparent glass substrate 15, and an electrochromic material 17 consisting of a thin film of tungsten oxide or the like is vapor-deposited on the electrode 16 in correspondence to the respective segments of the characters to be displayed. An insulation film 18 consisting of aluminum oxide or the like is formed on the remaining part of the electrode. Next, a white porous plate 19 consisting of ceramics or the like is provided by covering the material 17. Other one electrode 20 is disposed on the side opposite from the material 17. A caplike glass substrate 21 having flange 33 is secured onto the glass substrate 15 by means of an adhesive agent 22, and further a conductor 31 for power supply is formed on the substrate 15. A conductive elastic material 24 is interposed between the conductor 31 and the electrode 20. In this way, the electrode 20 and the conductor 31 are electrically connected by way of the elastic material 24. |
