An element of liquid crystal display including an orientation film. The orientation film is obtained by building up at least one monomolecular film on a substrate having thereon at least an electrode layer. The monomolecular film is formed by spreading an amphiphilic high-molecular weight substance having a number average molecular weight of from 2,000 to 300,000 having a repeating unit represented by formula (I): ##STR1## wherein R.sup.1 represents an aliphatic group having from 12 to 30 carbon atoms; and R.sup.2 represents at least one group selected from the group consisting of ##STR2## on a water surface, and subjecting the built-up film to a heat treatment to cause cyclization.
