Abstract: A liquid crystal aligning agent contains (1) at least one polymer selected from the group consisting of a polyamic acid obtainable by a reaction between a tetracarboxylic acid dianhydride and a diamine compound and an imidized polymer obtainable by cyclization with dehydration of the polyamic acid; (2) at least one first solvent selected from the group consisting of N-alkyl-2-pyrrolidones, lactones, and 1,3-dialkyl-2-imidazolidinones; (3) at least one second solvent selected from the group consisting of: (a) a first compound represented by general formula (I) wherein R is an alkylene group having 2 or 3 carbon atoms; R is an alkyl group having 1 to 4 carbon atoms an acetyl group or a propionyl group; R is an alkyl group having 1 to 3 carbon atoms, an alkoxyl group having 1 to 3 carbon atoms, or a halogen atom; a is 1 or 2; and b is 0 or integers of from 1 to 5; and (b) a second compound represented by general formula (II) wherein R is an alkyl group having 1 to 4 carbon atoms; R is an alkylene group having 2 or 3 carbon atoms; R is an alkyl group having 1 to 3 carbon atoms; and c is 1 or 2.
