ALIGNMENT FILM, ALIGNMENT FILM MATERIAL, LIQUID CRYSTAL DISPLAY DEVICE COMPRISING ALIGNMENT FILM, AND METHOD FOR MANUFACTURING SAME

摘要

An alignment film ( 100 ) according to the present invention contains polyimide ( 102 ) and a polyvinyl compound ( 104 ), the polyvinyl compound ( 104 ) containing a polymerization product of a polyfunctional monomer having a plurality of vinyl groups. Preferably, each of the plurality of vinyl groups of the polyfunctional monomer is a part of a methacrylate group or an acrylate group. Preferably, the polyfunctional monomer has two or more directly-bonded ring structures or one or more condensed ring structures between the plurality of vinyl groups. Preferably, both of the polyimide ( 102 ) and the polyvinyl compound ( 104 ) are present on the surface and in the interior.
