Abstract

The invention provides a liquid crystal alignment film with excellent burn-in properties, to which an alignment control function has been imparted with high efficiency, an imparted polymer composition and a liquid crystal display element using transverse electric field driving. The present invention provides a polymer composition [I] that includes (A) a branched polymer and (B) an organic solvent, wherein (A) is a photosensitive branched polymer that exhibits crystallinity in a specific temperature range and has a side chain represented by formula (0), and further has a side chain (a) containing a group selected from the nitrogen-containing aromatic heterocyclic group, amide group, and urethane group. In formula (0), G is selected from the groups in formulae (G-1), (G-12), (G-3), and (G-4), wherein the dotted line represents a bonding bond, R50 represents hydrogen atom and so on, J represents O, S, HH or NR51, and R51 represents an alkyl group with carbon number 1~3, and so on. The invention also provides a method for producing a substrate that has a liquid crystal alignment film, which comprises the following steps: a step of forming a coating film by applying the composition to a substrate having a conductive film for driving a transverse electric field, a step of irradiating the obtained coating film with polarized UV rays, and a step of heating the obtained coating film.
