Abstract
A method for continuously manufacturing an optical display panel includes feeding a carrier filmon which an optical filmis placed with a pressure-sensitive adhesive interposed therebetween, peeling off the optical filmfrom the carrier filmby using a folding-back partto inwardly fold back the carrier filmbeing fed, taking up the carrier filmfrom which the optical filmis peeled off, feeding an optical cell P and bonding the optical film, which is peeled off from the carrier film, to the optical cell P with the pressure-sensitive adhesive interposed therebetween, and reducing a difference between a first tension on the carrier filmlocated upstream of the folding-back partand a second tension on the carrier filmlocated downstream of the folding-back part while reducing one of the first and second tensions before the bonding step.
