Abstract:
1. A method for manufacturing an optical display unit, comprising: a cutting step comprising cutting a joined sheet product with exception of a release film which forms a part of the joined sheet product into a piece with a predetermined size by cutting means; and a bonding step comprising bonding the piece with the predetermined size to a substrate with a pressure-sensitive adhesive interposed therebetween while removing the release film; wherein the joint sheet product is manufactured by a method for manufacturing a joined sheet product comprising sheet products that are joined to each other and each comprise at least an optical member, a surface protecting member provided on one side of the optical member, and a release film provided on another side of the optical member with the pressure-sensitive adhesive interposed therebetween, comprising: a first joining step comprising opposing a transverse end face of a first sheet product to a transverse end face of a second sheet product and joining release films of the first and second sheet products with a first joining member; a removing step comprising removing a portion of an intended member including at least a surface protecting member so as to leave at least the release film and the pressure-sensitive adhesive provided on the release film among the constituent members of both or any one of the first and second sheet products, wherein the portion has a predetermined length from a transverse end face of the intended member; wherein the intended member includes a predetermined length portion of the first sheet product or a predetermined length portion of the second sheet product, toward which the release film will be peeled off from the joined sheet product in a longitudinal direction of the joined sheet product; and a second joining step comprising providing a second joining member on at least an exposed portion resulting from the removal of the intended member to join the surface protecting member sides of the first and second sheet products.
