PROBLEM TO BE SOLVED: To provide a liquid crystal aligning agent excellent in wetting property to a liquid crystal and giving a liquid crystal alignment film which makes a high pretilt angle. SOLUTION: The liquid crystal aligning agent contains at least one of a polyamic acid obtained by reacting fluorine-containing diaminotrifluoromethane and another diamine as diamines with a tetracarboxylic acid dianhydride and an imidated polymer produced by dehydration ring closure of the polyamic acid.
