Cinnamate-based photopolymerizable liquid crystal alignment material and method for manufacturing liquid crystal alignment layer using the same

摘要

The cinnamate-based light-polymerization type liquid crystal alignment material of the present invention has the structure represented by the following general formula (I) or (II);Wherein R_OneIs a group selected from the group consisting of a benzene ring and an alkyl group represented by the following bond capable of divalent bonding,;R₂Is a group selected from the group consisting of benzene rings represented by the following possible divalent bonds, R₃Is H or CH₃being;Wherein X is-F,-CN,-CF₃, Or-C_nH_{2n + 1}, N is an integer of 1 to 6, and R in the formula (II)_OneAnd R_One', R₂And R₂'Are different from each other.
