摘要： Provided are an optical display device manufacturing system and a method for manufacturing an optical display device which can bond optical films to both surfaces of a liquid crystal cell in good condition with a simpler constitution. A first optical film F11 is fed in an orthogonal direction with respect to the width direction from a first material roll R1 formed by winding the first optical film F11 in such a manner that an absorption axis B1 extends in the orthogonal direction, and then the first optical film F11 is cut and bonded to one surface of a liquid crystal cell. A second optical film F21 is fed in an orthogonal direction with respect to the width direction from a second material roll R2 formed by winding the second optical film F21 in such a manner that an absorption axis B2 extends in the width direction, and then the second optical film F21 is cut and bonded to the other surface of the liquid crystal cell. Accordingly, it is possible to bond the first optical film F11 and the second optical film F21 in the crossed nicols relation, without the provision of the mechanism for rotating the liquid crystal cell W or the like.
