Publication number: 20120241077Abstract: 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.
