A liquid crystal alignment agent includes a polymer and an organic solvent for dissolving the polymer. The polymer is obtained by subjecting a diamine composition and a tetracarboxylic dianhydride compound to a polymerization reaction. The diamine composition includes a first diamine compound, a second diamine compound, and a third diamine compound as defined in the specification.
A liquid crystal alignment film formed from the liquid crystal alignment agent and a liquid crystal display element including the liquid crystal alignment film are also disclosed.
