Abstract
An object of the present invention is to provide a forming method capable of obtaining an optical film in which occurrence of ghost can be suppressed in a case of being used in, for example, a virtual reality display apparatus; an optical film; a cholesteric liquid crystal layer; an optical laminate; and a production method of a curved-shaped optically functional layer. The object is achieved by a forming method including a heating step of heating an optical film, a forming step of pressing the optical film against a mold to deform the optical film, and a cutting step of cutting the optical film, in which the heating step is a step of heating the optical film by irradiating the optical film with infrared rays, and an irradiation amount of the infrared rays has a distribution in a plane of the optical film.
