    • The polymeric compound of this invention is represented by the following general formula (I): ##STR1## wherein A represents a hydrogen atom or ##STR2## B represents a hydrogen atom or ##STR3## each of X.sub.1 and X.sub.2 represents independently a hydrogen atom or a methyl group, each of m and n represents independently an integer of 0 to 14, each of p and q represents independently 0 or 1, and each of Y1 , Y.sub.2, Y.sub.3, and Y.sub.4 represents independently a hydrogen atom or a fluorine atom, with the proviso that both A and B are not hydrogen atoms, p is 0 when m is 0, and q is 0 when n is 0. The liquid crystal display element of this invention includes a pair of substrates oppositely disposed with a gap therebetween, and a liquid crystal layer placed in said gap, at least one of said substrates being transparent, and said liquid crystal layer having a liquid crystal region, and a polymer wall surrounded by said liquid crystal region, wherein said liquid crystal layer includes a liquid crystal material, a polymeric polymer material, and the above-described polymeric compound. The liquid crystal display element prepared from the polymeric compound of this invention does not cause disclination lines, and has bright characteristics in the absence of an electric voltage.
    • 本发明的高分子化合物由下列通式(I)表示:其中A表示氢原子或者A表示氢原子,或者X 1和X 2各自独立地表示 氢原子或甲基,m和n各自独立地表示0〜14的整数,p和q各自独立地为0或1,Y1,Y2,Y3和Y4各自独立地表示氢原子或 氟原子,条件是A和B都不是氢原子,当m为0时p为0,当n为0时q为0。本发明的液晶显示元件包括一对相对设置的基板 间隙,以及设置在所述间隙中的液晶层,至少一个所述基板是透明的,并且所述液晶层具有液晶区域和由所述液晶区域包围的聚合物壁,其中所述液晶层包括 液晶材料, 聚合物聚合物材料和上述聚合物。 由本发明的高分子化合物制备的液晶显示元件不会产生旋错线,并且在没有电压的情况下具有明亮的特性。
