LIQUID CRYSTAL ALIGNING AGENT AND LIQUID CRYSTAL DISPLAY

摘要

Disclosed is a liquid crystal aligning agent containing (a) at least one polymer selected from the group consisting of polyamic acids and imidized polymers thereof, and (b) a compound represented by the formula (A) below and having two epoxy groups in a molecule. (In the formula, R<SUP>01</SUP> represents a hydrogen atom or a monovalent organic group having 6-30 carbon atoms and bonded to the N atom by an aliphatic carbon.) This liquid crystal aligning agent is excellent in storage stability and adhesion to a substrate, and enables to form a tough coating film which hardly suffers from scratches due to rubbing processes performed under various conditions. Consequently, this liquid crystal aligning agent enables to form a liquid crystal alignment film having excellent liquid crystal aligning ability by performing a rubbing process on the surface of the coating film.
