METHOD FOR ALIGNING LIQUID CRYSTAL MOLECULE

摘要

PROBLEM TO BE SOLVED: To align liquid crystal molecules while controlling alignment tilt angle. SOLUTION: In a method for aligning the liquid crystal molecules by coating a substrate with a coating liquid for an alignment layer and forming the alignment layer and by coating the alignment layer with a coating liquid containing the liquid crystal molecules and forming a liquid crystal layer, a quaternary ammonium salt is added to the coating liquid for the alignment layer and the tilt angle of the liquid crystal molecules are controlled by an action of the quaternary ammonium salt.
