摘要: The present invention relates to an alignment treating agent for a liquid crystal cell, which comprises organic solvent-soluble polyimide resin comprising tetracarboxylic acid and diamine, at least 10 mol % of the diamine having bivalent group selected from consisting of: ##STR1## aligned film using does not require heat treatment high temperature time forming enables use substrate poor in heat-resistance, properties such as tilt angle voltage maintenance are deteriorated even after durability test temperature.
