  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。

  An object of the present invention is to provide a photoalignment layer with a more reliable absorption anisotropy parameter as a photoalignment layer that allows for reduced AC image-sticking. Specifically, provided is a photoalignment layer, obtained by exposure to polarized UV radiation, that has a maximum ΔA (=A1−A2, where A1 is the absorbance in a direction parallel to a vibration direction of the polarized UV radiation, and A2 is the absorbance in a direction parallel to the vibration direction of the polarized UV radiation) of 0.35 or more per micrometer of layer thickness in a range of 230 to 380 nm.
