The present invention relates to a liquid crystal alignment agent, a liquid crystal alignment film made by the liquid crystal alignment agent and a liquid crystal display element having the liquid crystal alignment film. The liquid crystal alignment agent includes a polymer composition (A) and a solvent (B). The polymer composition (A) is synthesized by reacting a mixture that includes a tetracarboxylic dianhydride component (a) and a diamine component (b). The aforementioned liquid crystal alignment agent has a better process stability, and the liquid crystal alignment film made by the liquid crystal alignment agent could improve the reliability of the liquid crystal display element.
