Beschreibung
Zusammenfassung:	The present invention provides a liquid crystal display element forming liquid crystal oriented agent of liquid crystal oriented film with excellent durability to long-time thermal stress, and avoiding deterioration of display capability even after long-time drive. The liquid crystal oriented agent includes a least a polymer selected from polyamic acid produced by reaction between tetracarboxylic dianhydride and diamine of a compound represented by the formula (A) and a matter group composed of polyimide produced by closing-ring dehydration of the polyamic acid, the liquid crystal display element includes a liquid crystal film formed with the liquid crystal oriented agent.
