The present invention aims to provide a liquid crystal aligning agent which can form excellent liquid crystal aligning performance and is excellently sealed with a liquid crystal layer, a liquid crystal alignment film formed by the liquid crystal aligning agent, phase difference film including the liquid crystal alignment film and manufacturing method thereof, a liquid crystal display device including the liquid crystal alignment film, and a polymer serving as a suitable ingredient of the liquid crystal aligning agent. The liquid crystal aligning agent provided by the invention contains A, i.e., an ingredient where the same or different molecule thereof contains optical aligning radicals and radicals containing polymerism double bonds. The ingredient A is optionally a polymer ingredient. The optical aligning radicals are optionally radicals containing a cinnamic acid structure. The liquid crystal alignment film is formed by the liquid crystal aligning agent. The phase difference film contains the liquid crystal alignment film. The phase difference film is optionally used in the liquid crystal display device. The liquid crystal display device contains the phase difference film.
