A method of producing an optical film having a plurality of convex-shaped microlenses disposed thereon, the method comprising the following steps A to F: step A: a step of rotating a roll die having an outer circumferential surface having a plurality of concave-shaped microlens transfer portions disposed thereon and running a substrate in a rotation direction of the roll die along the outer circumferential surface of the roll die; step B: a step of supplying an active energy ray-curable composition β onto a coating roll disposed to be adjacent to the outer circumferential surface of the roll die, flattening the active energy ray-curable composition β on the coating roll by a flattening means, and coating the flattened active energy ray-curable composition β on the outer circumferential surface of the roll die; step C: a step of supplying an active energy ray-curable composition α on the substrate and coating the active energy ray-curable composition α on a surface of the substrate; step D: a step of associating the active energy ray-curable composition α coated on the surface of the substrate in the step C and the active energy ray-curable composition β coated on the outer circumferential surface of the roll die in the step B at an association portion between the roll die and the substrate to form a liquid pool; step E: a step of irradiating a region between the outer circumferential surface of the roll die and the surface of the substrate with an active energy ray in a state in which the active energy ray-curable composition α and the active energy ray-curable composition β associated in the step D are sandwiched between the outer circumferential surface of the roll die and the surface of the substrate to cure the active energy ray-curable composition α and the active energy ray-curable composition β; and step F: a step of peeling off a cured product obtained in the step E from the roll die. step A: a step of rotating a roll die having an outer circumferential surface having a plurality of concave-shaped microlens transfer portions disposed thereon and running a substrate in a rotation direction of the roll die along the outer circumferential surface of the roll die; step B: a step of supplying an active energy ray-curable composition β onto a coating roll disposed to be adjacent to the outer circumferential surface of the roll die, flattening the active energy ray-curable composition β on the coating roll by a flattening means, and coating the flattened active energy ray-curable composition β on the outer circumferential surface of the roll die; step C: a step of supplying an active energy ray-curable composition α on the substrate and coating the active energy ray-curable composition α on a surface of the substrate; step D: a step of associating the active energy ray-curable composition α coated on the surface of the substrate in the step C and the active energy ray-curable composition β coated on the outer circumferential surface of the roll die in the step B at an association portion between the roll die and the substrate to form a liquid pool; step E: a step of irradiating a region between the outer circumferential surface of the roll die and the surface of the substrate with an active energy ray in a state in which the active energy ray-curable composition α and the active energy ray-curable composition β associated in the step D are sandwiched between the outer circumferential surface of the roll die and the surface of the substrate to cure the active energy ray-curable composition α and the active energy ray-curable composition β; and step F: a step of peeling off a cured product obtained in the step E from the roll die.
