The present invention provides an in-plane switching-type liquid crystal display element imparted with a high-efficiency alignment control function, and having excellent burn-in properties. The present invention also provides a manufacturing method for a substrate having a liquid crystal alignment film, said method having the following steps for obtaining a liquid crystal alignment film for an in-plane switching-type liquid crystal display element imparted with an alignment control function: [I] a step in which a polymer composition, which contains (A) a light-sensitive side chain polymer that exhibits liquid crystallinity at a prescribed temperature range and (B) an organic solvent, is coated on a substrate having a conductive film for in-plane switching, and a coating film is formed; [II] a step in which the coating film obtained in [I] is irradiated with polarized UV light; and [III] a step in which the coating film obtain in [II] is heated.
