Abstract:
Manufacturing method is for manufacturing an optical display panel including an optical cell and a pressure-sensitive adhesive layer-carrying optical film provided thereon with the pressure-sensitive adhesive layer interposed therebetween, which includes the steps of unwinding a multilayer optical film from a roll, feeding the multilayer optical film, feeding an optical cell, peeling off the optical film from a carrier film, and bonding the optical film to one side of the optical cell with a pressure-sensitive adhesive interposed therebetween, wherein the longitudinal length (L) of the carrier film between a position at which the multilayer optical film begins to be unwound in the film feeding step and a position at which peeling is started in the peeling step is 15 times or more the width (W) of the carrier film.
