Abstract
A manufacturing method of an optical film provided with a convexoconcave structure, comprises the steps of: coating a resin solution including a first resin solved by a solvent onto an endless or roll-like mold provided with a convexoconcave structure, and forming a resin solution layer on the mold; laminating a film substrate onto the resin solution layer to make a laminated film before the solvent in the resin solution layer is completely dried, the film substrate including a second resin, which is capable of absorbing the solvent or is soluble by the solvent; and peeling the laminated film from the mold before the solvent in the laminated film is completely dried.
