Abstract: A photo-aligning liquid crystal aligning agent for forming a liquid crystal alignment layer capable of materializing a liquid crystal display device, which has a high transmittance while maintaining a liquid crystal aligning property, a voltage holding ratio and the like, and in which flickering is inhibited from being caused after operating for a long time. The photo-aligning liquid crystal aligning agent contains [A] polyamic acid or a derivative thereof which is synthesized by reacting tetracarboxylic acid dianhydride and diamine, and [B] polyamic acid or a derivative thereof obtained by reacting tetracarboxylic acid dianhydride having no photoreactive structure and diamine having no photoreactive structure.

Abstract: A photo-aligning liquid crystal alignment layer formed by using a photo-aligning liquid crystal aligning agent containing polyamic acid or a derivative thereof which is synthesized by using tetracarboxylic acid dianhydride having no photoreactive structure having a specific structure and diamine having no photoreactive structure having a specific structure together with at least one of tetracarboxylic acid dianhydride having a photoreactive structure and diamine having a photoreactive structure can reduce storage of residual DC in a liquid crystal display device. Further, the above alignment layer can shorten the relaxation time and can prevent afterimages from being generated.
