Method and system for manufacturing optical display panel

摘要

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.

主权项

1. A method for manufacturing an optical display panel comprising an optical cell and a pressure-sensitive adhesive layer-carrying optical film provided on the optical cell with the pressure-sensitive adhesive layer interposed therebetween, the method comprising:
an unwinding step comprising providing a roll of a multilayer optical film comprising the optical film and a long carrier film placed on the optical film with the pressure-sensitive adhesive layer interposed therebetween and unwinding the multilayer optical film from the roll; a film feeding step comprising feeding the multilayer optical film being unwound from the roll in the unwinding step; an optical cell feeding step comprising feeding the optical cell; a peeling step comprising peeling off the optical film from the carrier film by inwardly folding back the carrier film fed by the film feeding step; and a bonding step comprising bonding the optical film, which is peeled off from the carrier film in the peeling step, to one side of the optical cell with the pressure-sensitive adhesive interposed therebetween while feeding the optical cell, wherein the longitudinal length (L) of the carrier film between an unwinding position at which the multilayer optical film begins to be unwound in the film feeding step and a peeling position at which peeling is started in the peeling step is 15 times or more the width (W) of the carrier film.
