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 may be cut to a length corresponding to the shorter side.

Provided is a system for manufacturing an optical display unit and a feed mechanism, which can well prevent an optical film and a pressure-sensitive adhesive layer from being peeled from a release film. A pressure-sensitive adhesive type sheet material, wherein the optical film and the pressure-sensitive adhesive layer (film main body (F)) are cut without cutting a release film (F12, F22) which is laminated to the optical film with the pressure-sensitive adhesive layer in between, is fed along a feed path (12A, 22A). A press member (200) is arranged at a position opposed to a bent portion or a curved portion in the feed path (12A, 22A). Since the film main body (F) which is peeled from the release film (F12, F22) can be pressed to the release film (F12, F22) by the press member (200), the film main body (F) can be well prevented from being peeled from the release film (F12, F22).

The invention provides a production management system and a production management method which are applied to an optical display device production system which can more precisely carry out a production management. A memory stores a panel information allocated per an optical display unit, and a roll information including a positional information of optical films in a material roll before the optical films bonded to the optical display unit are cut so as to coordinate. A position in the material roll before the optical films bonded to the optical display unit are cut is specified based on the panel information corresponding to the optical display unit of the optical display device determined by an inspecting apparatus that a defect exists, and the roll information coordinated to the panel information. If it is possible to recognize what position in what material roll the defect exists, as mentioned above, it is possible to carry out a production management more precisely.
