Title: LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Abstract:
The present invention provides a composition for producing a liquid crystal alignment film, whereby it becomes possible to produce a high-quality liquid crystal alignment film with high efficiency by expanding the range of the amount of emitted light in which an alignment control ability can be exerted stably. The present invention provides a liquid crystal aligning agent comprising (A) a side-chain-type polymer having a side chain that can exhibit liquid crystallinity in a specific temperature range and having a photo-reactive group capable of causing photocrosslinking, photoisomerization or photo-Fries rearrangement, (B) an organic solvent, and (C) an additive represented by formula (C) (wherein Rc1 and Rc2 are substituents for a benzene ring, and independently represent a halogen atom, an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a fluoroalkyl group having 1 to 10 carbon atoms, a fluoroalkenyl group having 2 to 10 carbon atoms, a fluoroalkoxy group having 1 to 10 carbon atoms, a carboxyl group, a hydroxy group, a (C1-10-alkyl)oxycarbonyl group, a cyano group or a nitro group; v and w independently represent the number of substituents on the benzene ring and independently represent an integer of 0 to 5).
