LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT FILM PRODUCED USING SAME, AND LIQUID CRYSTAL DISPLAY ELEMENT

WIPO Patent Application WO/2011/129414

A1

Disclosed is a liquid crystal aligning agent which can prevent the occurrence of a whitening phenomenon and a phenomenon of generating a foreign matter on a substrate, enables the production of a liquid crystal alignment film prevented from the reduction in a pretilt angle, and has a good aligning property. Specifically disclosed are: a liquid crystal aligning agent which is characterized by comprising a polyimide that is produced by imidizing a polyamic acid produced by reacting a diamine component with a tetracarboxylic acid dianhydride and a polyol compound that has a tertiary nitrogen atom and a quaternary carbon atom and contains 3 to 15 carbon atoms; a liquid crystal alignment film produced using the composition; and a liquid crystal display element.
