Electrochromic display

Abstract

Abstract PURPOSE:To reduce the quantity of electricity which is supplied to an electrochromic layer, and to improve a display contrast, by executing the display by the electrochromic layer consisting of two layers. CONSTITUTION:On the inside surface of a substrate is provided a transparent elecrically conductive film 6, on which an opposed electrode 7 is provided. On one surface of a substrate 2 is provided the first transparent electrode 8, on which the first EC layer is formed as a pattern. The surface of the transparent electrode 8 except the EC layer is covered with an insulation layer, and the space between the substrates 1, and 2 is packed with the first electrolytic layer. On the other surface of the substrate 2 is formed the second transparent electrode 12, and the second EC layer 13 is formed so as to it make the same display pattern as the first EC layer. The part except that which has formed the second EC layer is covered with an insulation layer 14. On the inside surface of a substrate 3 are formed a transparent conductive film 15 and the second opposed electrode 16, and the space between the substrate concerned 3 and said substrate 2 is packed with the second electrolytic layer 17. Voltage is applied between the transparent electrode 8 and an electrochromic layer 9, and between the transparent electrode 12 and the opposed electrode 16 to drive them.
