Provided are: a process for producing a liquid crystal alignment film, in which a heating procedure in the formation of the liquid crystal alignment film can be carried out at a relatively low temperature; and a liquid crystal display element. The present invention provides a process for producing a liquid crystal alignment film using a liquid crystal aligning agent that comprises at least one polymer selected from the group consisting of a polyamic acid and a polyimide and a solvent capable of solubilizing the polymer, wherein the process comprises: an application step of applying the liquid crystal aligning agent onto a substrate; a contact step of bringing the liquid crystal aligning agent that has been applied on the substrate into contact with a liquid which is compatible with the solvent and has a lower boiling point than that of the solvent and in which the polymer is poorly soluble or insoluble; and a film formation step of, subsequent to the contact step, heating the liquid crystal aligning agent on the substrate to form a coating film on the substrate. |
