  Provided are a liquid crystal alignment film capable of being given anisotropy through photoalignment and stable to light, and a liquid crystal display device capable of keeping a high voltage holding ratio without degradation of display quality even when exposed to strong light for a long period of time. To provide these, used is a liquid crystal aligning agent for photoalignment which contains a polymer having a structural unit containing a photoreactive structure and in which the structural unit containing a photoreactive structure undergoes chemical reaction by heating.

  提供了一种液晶取向膜，能够通过光取向获得各向异性，并且对光稳定，并且提供了一种液晶显示装置，即使长时间暴露在强光下也能保持高电压保持比率而不会降低显示质量。为了实现这些，使用了一种用于光取向的液晶取向剂，其中包含具有光反应结构的结构单元的聚合物，并且具有光反应结构的结构单元通过加热发生化学反应。
