Abstract:
1. A method of manufacturing a display substrate, the method comprising: forming a pixel unit on a base substrate; and coating a photoalignment material on the base substrate having the pixel unit, the photoalignment material including an alignment polymer, a photoalignment additive including a chemical compound represented by the following Chemical Formula 1 and an organic solvent; forming a preliminary layer by reacting the alignment polymer and the photoalignment additive and phase-separating a portion of the photoalignment additive adjacent to a surface of the preliminary layer; and irradiating light onto the base substrate having the preliminary layer to react the photoalignment additive to form an alignment layer having an orientation, wherein R R 3 represents an alkyl group having 1 to 12 carbon atoms, and each —CH 2 — of A and/or B is replaceable with —O—, and R 4 represents and each hydrogen atom excluding hydrogen atoms of R 4 is replaceable with chlorine (Cl) or fluorine (F).
