OPTICAL DISPLAY DEVICE MANUFACTURING SYSTEM AND MANUFACTURING METHOD, AND MATERIAL ROLL SET AND METHOD FOR MANUFACTURING SAME

摘要

There are provided a system and a method for manufacturing an optical display device, in which optical films fed from two rolls which are the same in the direction of optical anisotropy, such as the direction of absorption axis, can be bonded to one and the other surfaces of an optical display unit so that the optical anisotropy of the one can be orthogonal to that of the other, and a set of material rolls and a method for manufacture thereof. A first optical film F11 with a width corresponding to the short side of an optical display unit W has score lines that are previously formed so that the first optical film F11 can be divided by the score lines into pieces each having a length corresponding to the long side of the optical display unit W. A second optical film F21 with a width corresponding to the long side of the optical display unit W has score lines that are previously formed so that the second optical film F21 can be divided by the score lines into pieces each having a length corresponding to the short side of the optical display unit W. A first bonding apparatus 18 bonds a divided piece of the first optical film F11 with a length corresponding to the long side of the optical display unit W to one surface of the optical display unit W. A second bonding apparatus 28 bonds a divided piece of the second optical film F21 with a length corresponding to the short side of the optical display unit W to the other surface of the optical display unit W.
