Claim:
1. A method for continuously manufacturing an optical display panel, comprising the steps of: feeding a carrier film on which a pressure-sensitive adhesive-bearing optical film is placed with the pressure-sensitive adhesive interposed therebetween; peeling off the optical film together with the pressure-sensitive adhesive from the carrier film by using a folding-back part to inwardly fold back the carrier film fed by the feeding step; taking up the carrier film, from which the optical film is peeled off; bonding the optical film, which is peeled off from the carrier film, to an optical cell with the pressure-sensitive adhesive interposed therebetween by feeding the optical cell; and reducing a difference between a first tension on the carrier film located upstream of the folding-back part and a second tension on the carrier film located downstream of the folding-back part while reducing one of the first and second tensions before the bonding step.
