Abstract

A manufacturing system and manufacturing method for an optical display device, which adheres upper and lower optical films to the optical display device using two rolls having optical anisotropies in the same direction, so that the optical anisotropies are orthogonal to each other. The manufacturing system includes a first feeding device for feeding a first optical film after cutting to a predetermined length, and a second feeding device for feeding a second optical film after cutting to a predetermined length. The first feeding device and the second feeding device correspond to the longer side and the shorter side of the optical display unit, so that the optical film having a width corresponding to the shorter side may be cut to a length corresponding to the longer side, whereas the optical film having a width corresponding to the longer side may be cut to a length corresponding to the shorter side.
