摘要： A method for continuously manufacturing an optical display panel includes feeding a carrier film 12 on which an optical film 13 is placed with a pressure-sensitive adhesive interposed therebetween, peeling off the optical film 13 from the carrier film 12 by using a folding-back part 40a to inwardly fold back the carrier film 12 being fed, taking up the carrier film 12 from which the optical film 13 is peeled off, feeding an optical cell P and bonding the optical film 13, which is peeled off from the carrier film 12, to the optical cell P with the pressure-sensitive adhesive interposed therebetween, and reducing a difference between a first tension on the carrier film 12 located upstream of the folding-back part 40a and a second tension on the carrier film 12 located downstream of the folding-back part while reducing one of the first and second tensions before the bonding step.

The optical film roll has a width corresponding to a pair of opposite sides of a liquid crystal cell and is used by being cut to a length corresponding to another pair of opposite sides of the liquid crystal cell to be continuously attached to a surface of the liquid crystal cell. The optical film roll includes a long optical film wound into a roll shape, the long optical film being obtained by subjecting a long optical raw film, which includes a polarizing film having an absorption axis in its width direction, to a slitting process in a machine direction while conveying the long optical raw film in its lengthwise direction. The polarizing film includes a polyvinyl alcohol-based resin film that contains a dichromatic substance and has an Nz coefficient of 1.10 or more.
