PURPOSE:To obtain a fixed type electrochromic display device having a high responding speed and a long life by forming an electrochromic layer with a filmlike cross-linked electrochromic polymer. CONSTITUTION:A transparent electrode 2 and an electrochromic layer 3 are formed on a transparent substrate 1 in order, and an electrolytic soln. 4 is sealed in the space between the resulting display substrate and an opposite substrate 7 set opposite to the display substrate to obtain an electrochromic display device. At this time, the electrochromic layer 3 is formed with a filmlike cross-linked electrochromic polymer. The layer 3 has high adhesion to the substrate because of the filmlike state, and it is not dissolved in the org. electrolytic soln. because of the cross-linked state. As a result, a long life is provided. Since the layer 3 contacts with the substrate in larger area, the response is accelerated. |
