WIPO Patent Application WO/2016/056584

Kind Code:

A1

Abstract:

The present invention provides a composition for the production of a liquid crystal alignment film, said composition making it possible to efficiently obtain a high-quality liquid crystal alignment film in which an alignment control function is stable and the range of the resulting light irradiation amount is expanded. Provided is a composition for the production of a liquid crystal alignment film for an in-plane switching liquid crystal display element, said composition comprising: (A) a photosensitive side-chain polymer that exhibits liquid crystal properties in a predetermined temperature range; (B) a compound having the structure represented by formula (B) (in the formula, C1, C2, C3, and C4 each independently represent a phenyl group, a biphenyl group, or a napthyl group that may have a substituent, P1 and P2 each independently represent *-CH=N-* or *-N=CH-* (wherein * represents the bonding position with C1, C2, C3, or C4), L represents a straight chain or branched alkylene group that has 1-15 carbons atoms and that have may a substituent, n1 is an integer of 0-5, and m4 is an integer of 1-5); and (C) an organic solvent.
