Abstract

Disclosed is a liquid crystal alignment film which enables to attain a low, stable pretilt angle of a liquid crystal. Also disclosed is a liquid crystal aligning agent for obtaining such a liquid crystal alignment film. Specifically disclosed is a liquid crystal aligning agent characterized by being a solution containing at least one polymer selected from the group consisting of polymers obtained by reacting a diamine component containing an N-substituted diamine represented by the formula (1) below with a tetracarboxylic acid dianhydride, and polymers obtained by imidizing the thus-obtained polymers. Also specifically disclosed is a liquid crystal alignment film obtained from such a liquid crystal aligning agent. (In the formula (1), R1 represents a divalent organic group, namely a divalent linear hydrocarbon group having 1-5 carbon atoms, an organic group obtained by substituting an arbitrary hydrogen atom in the hydrocarbon group with a methyl group, or an organic group having a specific structure; and at least one of R2 and R3 represents a hydrocarbon group having 1-4 carbon atoms.)
