| 摘要 |
The invention provides a method for manufacturing an optical display device including an optical display unit and an optical film that includes a polarizing plate and is bonded to the optical display unit. The method comprises the steps of: unwinding and feeding a long sheet material from a roll of the long sheet material, wherein the long sheet material includes the optical film, a pressure-sensitive adhesive layer and a release film laminated in this order and has undergone a slitting process in a direction parallel or at a constant angle to an absorption axis of the polarizing plate so that it has a width corresponding to a short or long side of the optical display unit; inspecting the optical film of the fed long sheet material to detect a defect; cutting a part of the long sheet material other than the release film into a length corresponding to a long or short side of the optical display unit, while separating the detected defect; bonding a non-defective cut piece of the optical film to a surface of the optical display unit; and rejecting a defect-containing part of the optical film.
