PHOTOACTIVE CROSSLINKER COMPOUND, METHOD FOR PREPARING SAME, LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNING FILM, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

The present invention relates to a photoactive crosslinker compound, to a method for preparing same, to a liquid crystal aligning agent, to a liquid crystal aligning film, and to a liquid crystal display device. More particularly, the present invention relates to the photoactive crosslinker compound having a novel structure, to the method for preparing same, to the liquid crystal aligning agent, to the liquid crystal aligning film, and to the liquid crystal display device. According to the present invention, the liquid crystal aligning agent has high vertical alignment performance, good storage stability, superior transparency, and excellent liquid crystal aligning properties, printability, and electrical characteristics. Further, the stability of a pretilt angle and strength of the film can be improved, and a pretilt of a liquid crystal can be formed by UV exposure alone.
