摘要： An object of the invention is to provide a method and a system for manufacturing a liquid crystal panel, which allow more successful bonding of an optical film to a liquid crystal cell. A pressing force Fa per unit area applied when the optical film is pressed by the first roller and a pressing force Fb per unit area applied when the liquid crystal cell is pressed by the second roller satisfy the relation Fa>Fb. On the first roller side, the feed may fail to be stabilized due to the influence of tension fluctuations or vibration acting on the first optical film, so that air bubbles may occur. When the second roller side, where such an influence does not occur, contributes more to the feed of the liquid crystal cell, the liquid crystal cell can be successfully fed in the process of bonding the optical film thereto.

摘要： The present invention provides a method and apparatus designed to, during continuous manufacture of liquid crystal display panels, feed only a normal sheet to a lamination position for lamination to a rectangular panel and continuously laminate them together while positionally aligning them with each other. In the present invention, plural devices making up the entire apparatus are cooperatively associated with each other to make it possible that, among plural polarizing film sheets comprising a defect-free normal sheet and a defect-containing defective sheet each formed on a carrier film comprised in a strip-shaped film laminate. The normal sheet is reliably peeled from the carrier film by cooperatively associating feeding of the strip-shaped film laminate with a normal-sheet peeling device, and the defective sheet is reliably taken up while being attached to the carrier film, by cooperatively associating the feeding of the strip-shaped film laminate with a defective-sheet path changing device.
