Abstract

A method for manufacturing a display unit according to an exemplary embodiment of one aspect of the present invention includes: unwinding a first film from a first film roll, and carrying the first film; attaching a second film onto the carried first film and forming an elongated film laminated body; forming a cutting line in the film laminated body in a width direction at intervals along a longitudinal direction and forming a film sheet piece; and laminating the film sheet piece on a first surface of a panel.

Claims (12)

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.

2. The method for claim 1 , wherein the forming of the film laminated body includes, when a defect is formed in a facing region of the first film facing the second film, carrying the first film so that the defect is not included in the facing region of the first film and attaching the second film onto the first film.

3. The method for claim 1 , wherein the forming of the film laminated body includes attaching a second film sheet piece formed by forming a cutting line in the second film, which is carried in the second carrying direction, in a width direction at intervals along a longitudinal direction onto the first film.

4. The method for claim 1 , further comprising:

unwinding a third film from a third film roll, and carrying the third film;

forming a cutting line in the third film in a width direction at intervals along a longitudinal direction and forming a third film sheet piece; and

laminating the third film sheet piece on a second surface of the panel.
