Abstract

A novel alignment film for liquid crystal is prepared by depositing an organic solvent solution of an alkylalkoxy silane and an alkoxymetallic compound of Ti, Zr, Ge onto an electrode-side surface of substrate, and curing the solution on the substrate by heating. The alignment film shows good alignment for various types of liquid crystals and has long life.
