Abstract:
A photoalignment material includes an alignment polymer, a photoalignment additive including a compound represented by the following Chemical Formula 1 and an organic solvent. In Chemical Formula 1, R1 represents a cyclic compound. A and B independently represent a single bond or —(CnH2n)—. “n” represents an integer in a range of 1 to 12. Each —CH2— of A and/or B may be replaced with R3 represents an alkyl group having 1 to 12 carbon atoms, and each —CH2— of A and/or B may be replaced with —O—. R4 represents In Chemical Formula 1, each hydrogen atom excluding hydrogen atoms of R4 may be replaced with chlorine (Cl) or fluorine (F).
