Claim:
1. A method for manufacturing an optical display panel, comprising: a feeding step comprising feeding an optical cell with a thickness of 0.2 mm to 1.0 mm by means of a feed roller unit arranged perpendicular to a direction in which the optical cell is fed; a bonding step comprising feeding a long carrier film from a continuous roll, wherein the continuous roll is a roll of a laminate comprising the long carrier film and a pressure-sensitive adhesive-bearing optical film with a specific width placed on the carrier film, and bonding a sheet piece of the optical film, which is being peeled off or peeled off from the carrier film, to a lower surface of the optical cell with the pressure-sensitive adhesive interposed therebetween, wherein the lower surface is on a side in contact with the feed roller unit; and a rotation step comprising rotating the optical cell by 90° with respect to the direction in which the optical cell is fed, wherein the lower surface of the optical cell is covered with the sheet piece, which is bonded in the bonding step; wherein after the bonding step, the optical cell is curved convex upward when viewed from a side along the direction in which the optical cell is fed, and after the rotation step, the optical cell is curved convex upward when viewed from a front side with respect to the direction in which the optical cell is fed.
