  The invention concerns a smectic liquid crystal element and method of manufacture thereof. A polymer having spontaneous polarization as the liquid crystal is introduced into a liquid crystal layer of the smectic liquid crystal element in order to improve the response speed (second liquid crystal cell). The polymer has the same codes as the liquid crystal. Alternatively, a polymer having spontaneous polarization with opposite codes to the liquid crystal is introduced into a liquid crystal having a τ - Vmin characteristic so that a driving voltage is lowered (first liquid crystal cell). These polymers are added to a liquid crystal composite before injection into the liquid crystal cell. In a further aspect, after a photochemically polymeric monomer is added to the liquid crystal composite and the obtained product is injected into the liquid crystal cell, the monomer is polymerized by the application of light. Furthermore, the liquid crystal cell into which the polymer is introduced is heated again so as to exhibit isotropic phase and is cooled so that the tone display is realized.

  本发明涉及一种非晶态液晶元件及其制造方法。为了提高响应速度（第二液晶单元），将一种与液晶具有自发偏振性的聚合物引入到自密实液晶元件的液晶层中。该聚合物具有与液晶相同的编码。或者，在具有 τ - Vmin 特性的液晶中加入与液晶具有相反代码的自发极化聚合物，以降低驱动电压（第一液晶单元）。这些聚合物在注入液晶池之前被添加到液晶复合材料中。在另一个方面，将光化学聚合物单体添加到液晶复合材料中并将得到的产品注入液晶池后，单体在光的作用下发生聚合。此外，将引入聚合物的液晶池再次加热，使其呈现各向同性相，然后冷却，从而实现色调显示。
