The present invention relates to materials used for aligning liquid crystals of liquid crystal display elements and to a polymer for use in liquid crystal vertical alignment layer used in producing a liquid crystal vertical alignment layer.
The polymer for use in a liquid crystal vertical alignment layer includes (a) a moiety that is photochemically isomerizable but not photochemically crosslinked, (b) a moiety that is photochemically crosslinkable, and (c) a moiety that stabilizes a vertical alignment. The polymer can be used to produce a vertical alignment layer that has a liquid crystal alignment property enabling control of alignment at a low UV dose and that offers a large pretilt angle and superior optical stability.
本发明涉及用于对齐液晶显示元件的材料,以及用于制造液晶垂直对齐层的液晶垂直对齐层聚合物。用于液晶垂直对齐层的聚合物包括(a)具有光化学异构性但不具有光化学交联的基团,(b)具有光化学交联性的基团,以及(c)稳定垂直对齐的基团。该聚合物可用于制造具有液晶对齐性能的垂直对齐层,使得在低紫外线剂量下能够控制对齐,并提供大的预倾角和优异的光学稳定性。
