Beschreibung
Zusammenfassung:	A substrate with a liquid crystal alignment film for a lateral electric field drive liquid crystal display element is provided which is highly efficiently imparted with alignment control ability and which has excellent burn-in characteristics, and a lateral electric field drive liquid crystal display element having said substrate is also provided. A liquid crystal alignment agent is provided which contains a polymer having a structural unit represented by formula (3) (in formula (3), X1 is a tetravalent organic group derived from a tetracarboxylic acid derivative, Y1 is a divalent organic group derived from diamine represented in formula (1), R11 is an alkyl group with 1-5 carbons, and R21 is a hydrogen atom or an alkyl group with 1-4 carbons.)
