专利汇可以提供Color display device专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain effective information in accordance with an external state by placing in series in the traveling direction of a light, an electrochromic cell whose hue is varied by a voltage, and a liquid crystal whose passing light quantity is varied by a voltage. CONSTITUTION:Transparent substrates 11-13 are arranged in parallel through a separator. In the inside of the transparent substrate 11, display electrodes 22-29 of an electrochromic cell are arranged in accordance with a pattern, on which an electrochemical coloring substance 14 whose hue is varied by a voltage is laminated. On the upper side of the transparent substrate 12, an opposed electrode 30 of the electrochromic cell is provided, and between them, an electrolyte 15 is enclosed. On the lower side of the substrate 12, a polarizing plate 19 and a display electrode 21 are provided, on which an oriented film 17 is provided. On the transparent substrate 13, an opposed electrode 31 of the liquid crystal cell, and an oriented film 18 are provided, and a liquid crystal 16 is enclosed. On the outside of the transparent substrate 13, a polarizing plate 20 is provided. In this way, a white light source 4 is provided on the lower part of the polarizing plate 20, and by a voltage applied to each transparent electrode, the hue of bright and dark, and bright parts is controlled easily. This device is suitable for a dash board of an automobile.,下面是Color display device专利的具体信息内容。
