Beschreibung
Zusammenfassung:	Provided is a liquid crystal aligning agent from which it is possible to obtain a liquid crystal alignment film that achieves both a rapid DC brightness relaxation speed and suppression of flicker changes. This liquid crystal aligning agent is characterized by containing a polymer (A), a polymer (B) and a polymer (C). Polymer (A) is at least one type of polymer selected from the group consisting of (i) to (iii). (i) A poly(amic acid) obtained by means of a polymerization reaction between a diamine component containing at least one type of diamine selected from the group consisting of a diamine represented by formula [1] and a diamine represented by formula [2] and a tetracarboxylic acid component comprising an aromatic tetracarboxylic acid dianhydride. (ii) A poly(amic acid) ester obtained by means of a polymerization reaction between a diamine component containing at least one type of diamine selected from the group consisting of a diamine represented by formula [1] and a diamine represented by formula [2] a
