Abstract

PURPOSE:To obtaih a liquid-crystal display element which has superior transparency without coloring and an inconspicuous nesa pattern, by forming a liquid- crystal orientation film by using a specific poly Schiff base polymer. CONSTITUTION:A hydrazide phthalate compound shown by formula I and a phthalaldehyde compound shown by formula II are stirred in an organic solvent at about 10 deg.C for several hours to be condensed, thereby forming a poly Schiff base polymer. Next, the obtained polymer solution is diluted to a concentration of about 5-10wt% and applied onto an electrode substrate, and a heat treatment is performed at 150-300 deg.C to form a film of the polymer by removing the solvent. Then, an orientation film is formed by rubbing.
