Abstract:
1. A system for manufacturing an optical display device comprising a rectangular optical display unit and an optically-anisotropic optical film bonded to the optical display unit, comprising: a first bonding apparatus for bonding a divided piece of a first optical film to one surface of an optical display unit, wherein the divided piece of the first optical film has a length corresponding to a long side of the optical display unit and is obtained from a roll of a belt-shaped sheet material that comprises the first optical film and has score lines that are previously formed so that the first optical film can be divided by the score lines into pieces each having a length corresponding to the long side of the optical display unit, wherein the first optical film has a width corresponding to a short side of the optical display unit; a second bonding apparatus for bonding a divided piece of a second optical film to another surface of the optical display unit, wherein the divided piece of the second optical film has a length corresponding to the short side of the optical display unit and is obtained from a roll of a belt-shaped sheet material that comprises the second optical film and has score lines that are previously formed so that the second optical film can be divided by the score lines into pieces each having a length corresponding to the short side of the optical display unit, wherein the second optical film has a width corresponding to the long side of the optical display unit; and a feeder for transporting and feeding the optical display unit after the bonding of the first optical film, the feeder comprising a turning mechanism for turning the optical display unit to a bonding direction for the second bonding apparatus after the bonding in the first bonding apparatus.
