[Objects] To make it possible to carry out automatically and accurately a laminating operation of an optical element to a sheet-shaped body.[Means for Accomplishing the Objects] A strip-shaped polarizing film has a protective film strip conformably adhered to one surface thereof and a releasable liner conformably adhered to the other surface thereof and delivered from a film delivering station 1. After an appearance inspection, a lamination of the protective film strip and the polarizing film strip F is half-cut using a laser unit 11 to form an array of laminations each consisting of a protective film and a polarizing film F, with the releasable liner being left intact. Then, the polarizing films F are fed to a peeling mechanism 4. The peeling mechanism 4 feeds a forwardmost one the polarizing films F to a laminating mechanism 5 while peeling off the releasable liner therefrom by a knife-edged member. The forwardmost polarizing film F is laminated to a liquid-crystal panel W conveyed to the laminating mechanism by a panel transport apparatus 18 in synchronization of the feeding of the forwardmost polarizing film F.

A continuous manufacturing method and system for liquid-crystal display elements which enhances accuracy, increases speed and improves in yield in the continuous production of liquid crystal elements. The continuous method and system performs steps of, defining a plurality of defective and normal-polarizing-sheet slitting positions on a continuous web of optical film, based on positions of defects existing in the optical film, and applying only normal polarizing sheets to a liquid-crystal panel. The polarizing sheet includes the defective and normal-polarizing-sheet slitting positions recorded as encoded information which is used to determine whether the polarizing sheet defined between slit lines sequentially formed in the continuous web, is a normal polarizing sheet, peeling the normal polarizing sheet from the carrier film and applying the normal polarizing sheet to the liquid-crystal panel.

A method for aligning film sheets and rectangular panels in a continuous manufacturing system of display panels, each of the film sheets being formed between two longitudinally adjacent slit lines, one on an upstream side and the other on a downstream side, and extending in a transverse direction with respect to a feeding direction of a strip shaped film laminate, such that the rectangular panels conveyed to the lamination position are overlapped with the film sheets conveyed to the lamination position. The method includes steps of; angularly adjusting the rectangular panel conveyed to the lamination position such that a center line extending in the feeding direction of the rectangular panels is parallel to the center line extending in the feeding direction of the film sheets conveyed to the lamination position; and position adjusting the angularly adjusted rectangular panels by shifting for a displacement from a position of the film sheets conveyed to the lamination position.

A roll of optical-film laminate that increases accuracy, speed and yield in the production of liquid-crystal display elements. The roll of optical film laminate is for use in an apparatus for continuously producing liquid-crystal display elements. The optical film comprises a polarizing composite film of a laminate having a continuous web of polarizer and a protective film superposed on one side of the continuous polarizer, an adhesive layer disposed on one side of the laminate; and a carrier film superposed on the adhesive layer of the polarizing film in a peelable state. Defective and normal regions in the polarizing film are determined According to these determined regions, coded information that specifies positions of slit lines to be formed in the optical-film web are recorded on the continuous web.

There is provided a set of material rolls including two rolls that can be used simply by cutting each of them into a predetermined length and then can be bonded with high axis precision to an optical display unit in such a manner that their absorption axes can be orthogonal to each other, and is preferably less likely to produce defects from contamination of the system. There are also provided a method for production of the set of material rolls and a method for manufacturing an optical display device with the set of material rolls. The set of material rolls is for use in the process of bonding their pieces to both sides of an optical display unit, respectively, and includes: a first roll that is a roll of a long sheet material including a first optical film, a pressure-sensitive adhesive layer and a release film laminated in this order, wherein the first optical film includes a polarizing plate, and having undergone a slitting process in a direction parallel to the absorption axis of the polarizing plate so that it has a width corresponding to the short side of the optical display unit; and a second roll that is a roll of another long sheet material with a similar structure having undergone a slitting process in a direction parallel to the absorption axis of the polarizing plate so that it has a width corresponding to the long side of the optical display unit.
