ABSTRACT:
A liquid crystal aligning agent which can provide liquid crystal aligning capability through exposure to polarized radiation without rubbing and which is used to form a liquid crystal alignment film, a method of forming a liquid crystal alignment film, and a liquid crystal display element having this liquid crystal alignment film. An alignment film is formed from a liquid crystal aligning agent containing a polymer having a polyamic acid ester structure with a conjugated enone structure in the side chain and applying radiation to it from a predetermined direction. Thereby, a liquid crystal display element having high thermal stability in the alignment of liquid crystals and excellent display characteristics can be manufactured.
