A liquid crystal alignment agent contains a polymer composition, a polysiloxane, and a solvent. The polymer composition is obtained by subjecting a mixture including a tetracarboxylic dianhydride component and a diamine component to a reaction. The diamine component includes first and second diamine compounds. The polysiloxane contains an epoxy-based group. A liquid crystal display element made from the aforesaid liquid crystal alignment agent has reduced ion density.
