A liquid crystal alignment agent includes a polymer and an organic solvent for dissolving the polymer. The polymer is obtained by subjecting a diamine composition and a tetracarboxylic dianhydride compound to a polymerization reaction. The diamine composition includes a first diamine compound, a second diamine compound, and a third diamine compound as defined in the specification.
A liquid crystal alignment film formed from the liquid crystal alignment agent and a liquid crystal display element including the liquid crystal alignment film are also disclosed.
一种液晶取向剂包括聚合物和用于溶解聚合物的有机溶剂。该聚合物是通过将二胺组分和四羧酸二酐化合物进行聚合反应而获得的。该二胺组分包括在规范中定义的第一二胺化合物、第二二胺化合物和第三二胺化合物。还公开了由液晶取向剂形成的液晶取向膜和包括液晶取向膜的液晶显示元件。
