PROBLEM TO BE SOLVED: To provide a method for producing a plastic sheet which has excellent uniformity or flatness and excellent area large-sizeableness or mass productivity, and to provide the plastic sheet obtained by the producing method and a plastic substrate for display.SOLUTION: The method for producing the plastic sheet comprises: multi-stage ultraviolet light irradiation steps (D1, D2) at each of which a molding material packed in a molding die (W) is irradiated multiple times with the ultraviolet light from an ultraviolet lamp (L); and a direction changing step (J) of changing the conveying direction of the molding die by 90° so that the right-and-left ends of the molding die to be conveyed at the preceding ultraviolet light irradiation step (D1) becomes the back-and-forth ends of the molding die to be conveyed at the succeeding ultraviolet light irradiation step (D2). |
