Abstract

A liquid crystal alignment agent which is capable of forming a liquid crystal alignment film having good flattening property of sealant, the liquid crystal alignment film, and a liquid crystal display element having the same are provided. The liquid crystal alignment agent includes a polymer (A) and a solvent (B), wherein the polymer (A) is obtained by reacting a mixture including a tetracarboxylic dianhydride component (a) and a diamine component (b). The tetracarboxylic dianhydride component (a) includes at least one kind of tetracarboxylic dianhydride compound (a-1) represented by formula (1). The diamine component (b) includes at least one kind of diamine compound (b-1) represented by formula (2).
