LIQUID CRYSTAL ALIGNING FILM, METHOD FOR PRODUCING THE SAME, OPTICAL COMPENSATING SHEET, STN LIQUID CRYSTAL DISPLAY AND METHOD FOR ORIENTING DISCOTIC LIQUID- CRYSTALLINE MOLECULE

摘要

PROBLEM TO BE SOLVED: To stably orient discotic liquid-crystalline molecules in a substantially perpendicular and uniform direction and to obtain an optical compensating sheet suitable for an STN(super twisted nematic) liquid crystal display. SOLUTION: A (meth)acrylic acid copolymer having a 10-100C hydrocarbon group or a 1-100C fluorine substituted hydrocarbon group is added to an aligning film and discotic liquid-crystalline molecules are oriented at an average tilt angle in the range of 50-90 deg..
