<p><P>PROBLEM TO BE SOLVED: To provide a liquid crystal aligning agent that gives a liquid crystal aligning layer achieving favorable pretilt characteristics by a photo-aligning method and preventing degradation in display performance even in long-term continuous driving. <P>SOLUTION: The liquid crystal aligning agent contains at least one kind of polymer selected from a group consisting of a polyamic acid obtained by reacting a tetracarboxylic acid dianhydride with diamine including a first diamine represented by a compound expressed by formula (A-1-1) and a second diamine having a photo-reactive structure, and polyimide obtained by a dehydration and ring closure of the polyamic acid. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
