Disclosed is a liquid crystal aligning agent which is capable of providing a liquid crystal alignment film that is resistant to film separation or chipping during a rubbing process, has high voltage holding ratio, and does not easily accumulate electrical charges at the initial stage even when a direct current voltage is applied thereto. Specifically disclosed is a liquid crystal aligning agent that contains at least one kind of polymer selected from among polyamic acids, each of which is obtained by having a diamine component containing a diamine represented by formula (1) react with a tetracarboxylic acid dianhydride component, and polyimides that are obtained by imidizing the polyamic acids. (In the formula, Ar represents an isocyclic aromatic compound or a nitrogen atom-containing heterocyclic aromatic compound, and the hydrogen atom on a carbon atom or nitrogen atom constituting the ring may be substituted.) |
