Beschreibung
Zusammenfassung:	The invention discloses a polyamino compound capable of being used for synthesizing a liquid crystal aligning agent, the liquid crystal aligning agent, a liquid crystal alignment film and a liquid crystal display element, and belongs to the technical field of liquid crystal display. The structure of the polyamino compound is shown as a general formula (1) (See the specification). The liquid crystal aligning agent prepared from the polyamido compound can effectively improve the hardness of the alignment film and the charge release speed of the liquid crystal display element, that is, the liquidcrystal aligning agent has lower RDC and higher hardness value, so that the display effect of the liquid crystal display element is improved, and the yield is increased. 本发明公开了一种可用于液晶取向剂合成的多胺基化合物、液晶取向剂、液晶取向膜以及液晶显示元件，属于液晶显示技术领域，本发明一种多胺基化合物，结构如通式(1)所示；本发明多胺基化合物制备的液晶取向剂可以有效的提高取向膜的硬度及液晶显示元件的电荷释放速度，即具有较低的RDC和较高的硬度值，从而改善液晶显示元件显示效果及提高良率。
