LIQUID CRYSTAL ALIGNMENT LAYER, OPTICAL COMPENSATION SHEET, AND METHOD FOR ALIGNING DISCOTIC LIQUID CRYSTALLINE MOLECULE

摘要

PROBLEM TO BE SOLVED: To stably align discotic liquid crystalline molecules in a substantially horizontal direction. ;SOLUTION: The copolymer consisting of a comparatively weekly hydrophobic recurring unit having a 1-9C hydrocarbon group at a terminal of its side chain and a hydrophilic recurring unit having a hydrophilic substituent, the substituted vinyl monomer corresponding to which is water-soluble, is used for an alignment layer.;COPYRIGHT: (C)2003,JPO
