Abstract

Disclosed is a liquid crystal aligning agent having a characteristic to increase the pretilt angle of a liquid crystal, which is capable of vertically aligning liquid crystals even with a small amount of use. Also disclosed is a liquid crystal display device using such a liquid crystal aligning agent. Specifically disclosed is a liquid crystal aligning agent characterized by containing the following components (A) and (B). Component (A): a polyimide having a carboxyl group in a molecule, which is a polymer obtained by imidizing a polyamide acid having a repeating unit represented by the structural formula [1] below Component (B): an amine compound having one primary amino group and a nitrogen-containing aromatic heterocyclic ring in a molecule, wherein the primary amino group is bonded to an aliphatic hydrocarbon group or a non-aromatic cyclic hydrocarbon group (In the formula [1], R1 represents a tetravalent organic group; and R2 represents a divalent organic group including the group represented by the following formula [2].) (In the formula [2], X1 represents a phenylene; X2 represents a cyclohexylene or a phenylene; X3 represents a cyclohexylene; and X4 represents an alkylgroup having 3-12 carbon atoms, an alkoxy group having 3-12 carbon atoms, a fluoroalkyl group having 3-12 carbon atoms or a fluoroalkoxy group having 3-12 carbon atoms.)
