PURPOSE:To eliminate color shading caused by the fluctuation in resistance and to obtain an easily noticeable display pattern, by applying a metallic electrode whose resistance value is lower than that of the transparent electrode, to the lead wire and counter electrodes of the transparent electrode pattern installed on a transparent substrate. CONSTITUTION:A lead wire part composed of a metallic film 7 is formed by vapor-depositing a metal on a transparent electrode pattern 1 installed on a transparent substrate 2, and a transparent insulating film 6 is formed by vapor-depositing an insulator, such as SiO2, etc., in the lead wire part. Then, after an electrochromic display substance 3 composed of more than two kinds of transition metallic compounds is vapor-deposited, the metal 7 which is used for forming the lead wire part is vapor-deposited on the whole display panel, and thus, counter electrodes are formed. In this way, the color developing speed of each segment dan be set equally and the lead wire is made in such a way that it cannot be discriminated easily. |
