Abstract: A method and apparatus for manufacturing a polarizer for use in a large-sized liquid crystal display (LCD) with a size of 60 inches or more includes controlling the degree of stretching of a PVA film to have a width corresponding to a length of a long side of an LCD panel, cutting the stretched PVA film to fabricate PVA sheets, and attaching TAC films and protection films to each of the PVA sheets. Since the PVA film is fabricated into the PVA sheets, it is possible to fabricate a polarizer without changing the widths of the TAC films and protection films. Therefore, costs can be reduced that are associated with facility investment for manufacturing polarizers for LCDs having a size of 60 inches or more.
