Beschreibung
Zusammenfassung:	Provided are: a liquid crystal aligning agent which has excellent whitening resistance and coating film uniformity; a liquid crystal alignment film; and a liquid crystal display element. A liquid crystal aligning agent which is characterized by containing at least one polymer that is selected from the group consisting of polyimide precursors having a partial structure represented by formula [U] and a side chain structure selected from the group consisting of structures of formulae [S1] and [S2] and a steroid skeleton and polyimides that are imidized products of the polyimide precursors. In theformulae, the symbols are as defined in the description. 提供耐白化性及涂膜均匀性优异的液晶取向剂、液晶取向膜及液晶表示元件。一种液晶取向剂，其特征在于，其含有选自由聚酰亚胺前体及作为该聚酰亚胺前体的酰亚胺化物的聚酰亚胺组成的组中的至少一种聚合物，所述聚合物具有下述式[U]所示的部分结构、并且具有选自由下述式[S1]、[S2]及甾体骨架组成的组中的侧链结构。(式中的符号的定义如说明书中所记载。)；-X-R[S2]。
