Abstract: A liquid crystal photo-alignment agent includes a polyimide copolymer including a first structure unit represented by the described Chemical Formula 1 and a second structure unit represented by the described Chemical Formula 2, and, based on a 100 mole % sum total of the first structure unit and the second structure unit, the first structure unit is included in an amount of 70 to 95 mole % and the second structure unit is included in an amount of 5 to 30 mole %. A liquid crystal photo-alignment film may be manufactured using the same, and a liquid crystal display may include the liquid crystal photo-alignment film.
