Abstract

PURPOSE:To obtain a liquid-crystal display element of multilayer structure which has superior transparency and an inconspicuous nesa pattern, by forming a liquid- crystal orientation film by using a specific hydrazide copolyer. CONSTITUTION:A dibasic acid hydrazide compound (A) (e.g., dihydrazide phthalate) shown by the formula (where R is an aromatic compound or aliphatic compound), a diamine compound (e.g., P-phenylenediamine) (B), and tetracarboxylic dianhydride (C) (e.g., pyromellitic dianhydride) are stirred in an organic solvent at about 10 deg.C for several hours to be condensed, so that a copolymer will be formed. Next, the obtained polymer solution is diluted to a concentration of about 5-10wt% and applied to an electrode substrate, which is heated at 150-300 deg.C to remove the solvent; after a film of polymer is formed by closing the ring, and rubbing is performed to obtain the orientation film.
