Processes of synthesizing aromatic amine-based benzoxazine resins are disclosed. The processes provide new routes for synthesizing benzoxazine from aromatic diamines or multifunctional aromatic amines that may solve the problem of insoluble products resulted from the condensation of hydroxymethylamine with amine by using aromatic diamine, phenol and formaldehyde as a raw materials.

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.
