Abstract: Provided is a liquid crystal photo alignment agent including: a solid including at least one of a polyimide polymer, cyclobutane dianhydride (CBDA) or diamine; a first solvent including at least one of N-methyl-2-pyrrolidone, N-ethyl-2-pyrrolidone, dimethyl sulfoxide, dimethyl formamide, γ-butyrolacton or propylene carbonate; and a second solvent including at least one of propylene glycol monobutyl ether, dipropylene glycol monomethyl ether, propylene glycol n-propyl ether, diethylene glycol diethyl ether or diacetone alcohol, wherein the first solvent is included in an amount of about 50 wt % to about 80 wt % based on the total weight of the liquid crystal photo alignment agent; and the second solvent is included in an amount of about 15 wt % to about 40 wt % based on the total weight of the liquid crystal photo alignment agent. Also provided is a method of manufacturing a liquid crystal display including the liquid crystal photo alignment agent.
