    Abstract: A method of manufacturing a photoalignment layer includes: applying a photoalignment agent including a copolymer of at least one of cyclobutanedianhydride and a cyclobutanedianhydride derivative, and diamine, and a crosslinking agent including an alkylene group having a formula —CnH2n—, wherein n is a natural number, on a substrate; pre-baking the photoalignment agent applied on the substrate to form a pre-baked photoalignment agent; hard-baking the pre-baked photoalignment agent to form a hard-baked photoalignment agent; irradiating the hard-baked photoalignment agent with a light source thereby photoaligning the photoalignment agent; and secondarily baking the photoalignment agent irradiated with the light source, where in the application of the photoalignment agent on the substrate, the photoalignment agent applied on an edge portion of the substrate is applied in about 30 to about 70 wt %, relative to the photoalignment agent applied on the center portion of the substrate.

    Abstract: A liquid crystal display may be manufactured by forming a first alignment layer on a first base substrate, forming a second alignment layer on a second base substrate, disposing liquid crystal on the first alignment layer or the second alignment layer, and combining the first base substrate and the second base substrate with each other. At least one of the first and second alignment layers may be formed by forming an alignment solution including an alignment agent and a cross-linking agent on the first or second base substrate. The alignment solution is cured at a first temperature to form an alignment layer. The base substrate is exposed to light or an electron beam to align the alignment layer. The alignment layer is baked at a second temperature. The first temperature is lower than a cross-linking reaction temperature of the cross-linking agent.
