Abstract
Provided are a manufacturing system and a manufacturing method for an optical display device, which are enabled to adhere upper and lower optical films to an optical display device by using two rolls having optical anisotropies such as absorption axes in the same direction, so that the optical anisotropies may be orthogonal to each other. In the manufacturing system for the optical display device, the optical films are adhered to an optical display unit (W). The manufacturing system comprises a feeding device (M2) for a first optical film (F11) to be fed after cut to a predetermined length, and a feeding device (M5) for a second optical film (F21) to be fed after cut to a predetermined length. The feeding device (M2) of the first optical film (F11) and the feeding device (M5) of the second optical system (F21) are so constituted in a manner to correspond to the longer side and the shorter side of the optical display unit (W), that one feeding device may cut the optical film having a width corresponding to the shorter side may be cut to a length corresponding to the longer side whereas the other feeding device may cut the optical film having a width corresponding to the longer side …
