Alignment layer for liquid crystal display

摘要

Liquid crystal displays are improved by using as the alignment layer an alkali-soluble resin which is an addition resin of (a) at least one ethylenically unsaturated, ligand-free monomer and (b) at least one ethylenically unsaturated monomer having at least one carboxyl group. The resin is optically clear and is characterized by being exceptionally stable.
