  • Patent number: 5187607
    Abstract: An electrochromic device is constructed with a first electrode layer, an electrochromic layer and a second electrode layer formed on a substrate in sequence, with at least one of the first and second electrode layers being a transparent electrode layer. The device is characterized in that a conductive thin film having a resistance lower than that of the transparent electrode layer is formed on part of the substrate, and part of the transparent electrode layer is formed on this conductive thin film. Alternatively, the conductive thin film is formed in contact with a part of the transparent electrode layer formed on an end surface of the substrate, and the area of the conductive thin film is larger than a corresponding underlying cross-sectional area of the substrate taken in the direction of the substrate thickness.
