A liquid crystal aligning agent and a liquid crystal display device using the liquid crystal aligning agent are provided to obtain satisfactory coating uniformity even in case of the temperature change of environment in a printing process and to reduce cratering in case of printing. A liquid crystal aligning agent comprises a poly(amic acid) obtained by reacting tetracarboxylic dianhydride and a diamine compound, an imidation polymer having a structure obtained by dehydration and ring closing of poly(amic acid), or a mixture of poly(amic acid) and the imidation polymer; and at least one solvent selected from an amide-based solvent represented by the formula 1, wherein R1 is a C1-C4 alkyl group; and R2 is a C1-C8 alkyl group, a benzyl group or a phenethyl group.
