<P>PROBLEM TO BE SOLVED: To provide a liquid crystal aligning agent which provides a liquid crystal alignment film having excellent liquid crystal alignment capability and seize resistance, and further which has an excellent coating property. Ž<P>SOLUTION: The liquid crystal aligning agent includes an imidized polymer produced by dehydration ring-closing of a polyamic acid obtained by reacting a tetracarboxylic acid dianhydride with a diamine containing at least one selected from a group comprising 1,3-bis(4-aminophenoxy) benzene, 1,3-bis(3-aminophenoxy) benzene, 1,4-bis(4-aminophenoxy) benzene, bis[4-(4-aminophenoxy) phenyl] ether, and 4,4'-bis(4-aminophenoxy) biphenyl, of 3-30 mol% with respect to the total diamine.
