1. A method for manufacturing a display unit, the method comprising:
unwinding a first film from a first film roll, and carrying the first film in a first carrying direction;
unwinding a second film from a second film roll positioned perpendicular to the first film roll, and carrying the second film in a second carrying direction that is perpendicular to the first carrying direction;
attaching the second film onto the carried first film, wherein, as a result of the first carrying direction of the first film and the second carrying direction, the second film is attached to the first carried film so that an absorption axis of a polarizing plate on the first film is perpendicular to a transmission axis of a brightness improving film on the second film, and forming an elongated film laminated body;
forming a cutting line in the film laminated body in a width direction at intervals in a longitudinal direction and forming a film sheet piece; and
laminating the film sheet piece onto a first surface of a panel.
