Beschreibung
Zusammenfassung:	Provided is a liquid crystal aligning agent that forms a liquid crystal alignment film having good rubbing resistance, good printability even when the imidization rate is high, an excellent voltage retention rate, a high accumulated charge, and the like. This liquid crystal aligning agent is characterized by comprising a soluble polyimide represented by formula (1), and a polyamic acid ester represented by formula (2). (X1 is a tetravalent organic group, Y1 is a divalent organic group, X2 is a tetravalent organic group, Y2 is a divalent organic group, R1 is a C1-5 alkyl group, A1 and A2 each independently are a hydrogen atom, or a C1-10 alkyl group, alkenyl group, or alkynyl group which may optionally have a substituent.)
