Beschreibung
Zusammenfassung:	This liquid crystal alignment agent contains a polymer component and a cyclic siloxane compound [A] having a cross-linkable group. One embodiment of the cyclic siloxane compound [A] is represented byformula (1). In formula (1), R1-R6 each independently represent a hydrogen atom or a monovalent organic group having 1-20 carbon atoms. At least one of R1-R6 is a monovalent organic group having a cross-linkable group, and n is an integer of 1-18. When n is 2 or more, a plurality of R1s may be identical to or different from each other and a plurality of R2s may be identical to or different from each other. 液晶取向剂中含有：聚合体成分；以及具有交联性基的环状硅氧烷化合物[A]。环状硅氧烷化合物[A]的一形态为式(1)所表示的化合物。式(1)中，R1～R6分别独立地为氢原子或碳数1～20的一价有机基。其中，R1～R6中的至少一个为具有交联性基的一价有机基。n为1～18的整数。在n为2以上的情况下，多个R1彼此可相同也可不同，多个R2彼此可相同也可不同。
