    • The invention relates to a method of forming a display comprising the steps of (a) providing a substrate; (b) forming a plurality of first conductors over the substrate, and optionally one or more circuits; (c) depositing a layer of cholesteric liquid-crystal material, in the form of droplets of liquid crystal in a liquid carrier, over a preselected area of each of said first conductors so that a preselected portion of each of said first conductors is uncoated; (d) drying the liquid carrier to form a layer of polymer-dispersed cholesteric-liquid-crystal domains in a continuous matrix; and (e) forming a plurality of second conductors, electrically isolated from the first conductors, over the layer of polymer-dispersed liquid-crystal domains so that an electric field between the second conductors and the uncoated portions of the first conductors is capable of changing the optical state of the polymer-dispersed cholesteric liquid-crystal material. The absence of a coating over the second conductors permits connection to the first conductors without additional processing steps. The invention is also directed to a display element made by the method and to an array of display elements that represent an intermediate in the production of the final form of the display elements.
    • 本发明涉及一种形成显示器的方法,包括以下步骤:(a)提供基底; (b)在衬底上形成多个第一导体,以及可选地一个或多个电路; (c)将液晶体液滴形式的胆甾型液晶材料层沉积在每个所述第一导体的预选区域上,使得每个所述第一导体的预选部分未被涂覆; (d)干燥液体载体以在连续基质中形成聚合物分散的胆甾醇 - 液晶畴的层; 和(e)在聚合物分散的液晶畴之上形成多个与第一导体电隔离的第二导体,使得第二导体和第一导体的未涂覆部分之间的电场能够改变 聚合物分散的胆甾型液晶材料的光学状态。 在第二导体上没有涂层允许连接到第一导体,而没有额外的处理步骤。 本发明还涉及通过该方法制成的显示元件以及在生产显示元件的最终形式中的中间体的显示元件阵列。
