LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

Provided is a liquid crystal aligning agent, which is suitable for a liquid crystal display element having a high response speed, and for a PSA-type liquid crystal display element in particular. The liquid crystal aligning agent is characterized by containing a polymer having a side chain structure represented by formula (I). (I) (Ar represents an aromatic hydrocarbon group, R1 and R2 represent C1-10 alkyl groups or the like, T1 and T2 represent single bonds or the like, S represents a single bond or the like, and Q represents the following structure.) (II) (R represents a hydrogen atom or the like, and R3 represents -CH2- or the like.)
