Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal aligning agent for giving a liquid crystal alignment layer that maintains good liquid crystal aligning property even when the element is continuously driven for a long time, and maintains short afterimage erasing time. SOLUTION: The liquid crystal aligning agent contains: (A) at least one kind of polymer selected from the group consisting of polyamic acids and polyimide; and a specified aziridine compound represented by a compound expressed by formula (B-1). In formula (B-1), RIand RIIeach represent a hydrogen atom or a methyl group; and each XIrepresents a single bond or -NHCO-(where a bond with is bonded to a nitrogen atom). COPYRIGHT: (C)2011,JPO&INPIT
