Beschreibung
Zusammenfassung:	A liquid crystal alignment agent, a liquid crystal alignment film, a liquid crystal display device and a reaction product are provided. The liquid crystal alignment agent has a low degree of decreasein voltage holding ratio resulting from light (especially ultraviolet light). The liquid crystal alignment agent is characterized by being prepared from: a polymer (A) containing at least one polymerselected from a group consisting of polyamic acid, imidized polymer thereof, polyamic acid ester and polyorganosiloxane; and a specific compound (B) represented by a compound of the following formula. 本发明提供种液晶取向剂、液晶取向膜、液晶显示元件及反应产物，所述液晶取向剂的由光(特别是紫外光)引起的电压保持率下降的程度少。本发明的液晶取向剂的特征在于使用以下化合物来制备：(A)含有选自由聚酰胺酸、其酰亚胺化聚合物、聚酰胺酸酯以及聚有机硅氧烷所组成组群中的至少1种聚合物的聚合物；以及(B)下述式的化合物所代表的特定化合物。
