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.
