ELECTROCHROMIC DISPLAY ELEMENT

摘要

PURPOSE:To obtain a display element with long life and high speed response by forming a filmlike electrochromic material obtained by mixing an electrochromic substance forming/deforming colors with high molecule on a display electrode. CONSTITUTION:A filmlike electrochromic material 7 obtained by mixing an electrochromic substance such as methylviologen which forms/deforms colors at the application of voltage with an water insoluble high molecule in the mole ratio of 1:2-10 is formed on a display electrode 2 attached to a base plate 1. The base plate 1 is opposed against a base plate 1 attaching an opposed electrode 3 through a spacer 4 and an electrolyte solution 6 including a redox component is enclosed inside the space between base plates 1. Since the electrochromic substance is fixed in the film formed on the display electrode, the speed of the action to form/deform colors is controlled in the process of load transfer and the display with the high speed response of 1 to 10msec can be realized.
