Abstract

An object of the present invention is to provide a method of manufacturing an optical film product by die-cutting an optical film sheet or an optical film sheet unfolded from a roll, which makes it possible to reliably and easily distinguish between the front and back sides and between the top and bottom surfaces of the optical film product, so as to manufacture the optical film product reliably with a higher yield of production. In the method of manufacturing an optical film product by die-cutting an optical film sheet or an optical film sheet unfolded from a roll, it is characterized in that it comprises a step of die-cutting the optical film by means of a cutting die having a stamping blade provided on part thereof to make a film provided with a stamp mark.
