Title:
LIQUID-CRYSTAL ALIGNMENT AGENT, LIQUID-CRYSTAL ALIGNMENT FILM, AND LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/053232
Kind Code:
A1
Abstract:
This liquid-crystal alignment agent contains a polymer, a polymerizable compound, and a solvent. The polymerizable compound has a polymerizable unsaturated bonding group, a functional group that forms a hydrogen bond, and at least one aromatic ring near said functional group. The functional group forms intermolecular hydrogen bonds so as to form a mesogenic structure.
