This invention relates to a photoactive crosslinking agent compound, its manufacturing method, a liquid crystal aligning agent, a liquid crystal aligning film, and a liquid crystal display element. More specifically, it relates to a photoactive crosslinking agent compound having a novel structure, a manufacturing method thereof, a liquid crystal aligning agent, a liquid crystal aligning film and a liquid crystal display element. According to the present invention, it is possible to provide a liquid crystal aligning agent having high vertical alignment performance, good storage stability, excellent transparency, and excellent liquid crystal alignment, printability and electrical properties. Moreover, the stability and film | membrane intensity | strength of the pretilt angle of a liquid crystal aligning film can be improved more, and the pretilt of a liquid crystal can be formed only by UV exposure. |
