PURPOSE:To maintain a response rate for long periods and to make coloring and discoloring clear by applying a composite ion exchange film obtd. by laminating the plural numbers of the ion exchange films having the same electric charge and different sorts of the ion exchange groups, to the element. CONSTITUTION:The transparent conductive film, the electrochromic film, the ion exchange film and the counter electrode are laminated on the substrate in order, to form the ECD element. The ion exchange film which is prepared by laminating the plural numbers of the ion exchange films having the same electric charge and the different ion exchange groups, is used. The coloring and the discoloring of the titled element are controlled by the hydrogen ion, and the response rate of the titled element is changed by changing the amount and the mobility rate of the hydrogen ion. By combining the plural numbers of the ion exchange films having different degrees of dissociation which influences to the ion transfer rate, the merit of each ion exchange film is exhibited thereby improving each performances of the response rate, the working life, the power consumption and the contrast ratio of the titled element, and balancing each performances.
