  • PHOTOALIGNMENT MATERIAL, DISPLAY SUBSTRATE HAVING AN ALIGNMENT LAYER FORMED USING THE SAME, AND TO A METHOD OF MANUFACTURING THE DISPLAY SUBSTRATE
    Publication number: 20090290109
    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). Thus, an alignment layer having an orientation may be formed without an alignment polymer having a photoreactive portion, and the density of the alignment layer may be increased.
