An alignment film ( 100 ) according to the present invention includes: a first alignment layer ( 102 ) containing a first polyimide ( p1 ); and a second alignment layer ( 104 ) containing a polymerization product ( po ) resulting from polymerization of a polyfunctional monomer and a second polyimide ( p2 ). The polyfunctional monomer is represented by general formula (1) P1-A1-(Z1-A2)n-P2 (in general formula (1), P1 and P2 each independently of the other are an acrylate, methacrylate, acrylamide, methacrylamide, vinyl, vinyloxy, or epoxy group; A1 and A2 each independently of the other represent a 1,4-phenylene, 1,4-cyclohexane, 2,5-thiophene, or naphthalene-2,6-diyl group; Z1 is a -COO-group, a -OCO- group, a -O- group, a -CONH- group or a single bond, where n is 0, 1, or 2).
