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

摘要

The present invention pertains to a polymer composition containing: (A) a photosensitive side-chain polymer that exhibits liquid crystallinity within a prescribed temperature range; (B) a polymer having a side chain indicated by formula (b) [in the formula, A, B, S, T, X, P, Q, l1, l2, l3, b1, and b2 are as defined in the Description]; and (C) an organic solvent. In addition, the present invention pertains to a liquid crystal alignment film obtained from said composition and a production method for a substrate having said liquid crystal alignment film. As a result of the present invention, a novel polymer composition and a liquid crystal alignment film for in-plane switching liquid crystal display elements using same can be provided, said novel polymer composition providing a liquid crystal alignment film for in-plane switching liquid crystal display elements that is highly efficient, has alignment control properties, and has excellent electrical characteristics.
