Patent ID: 8088463

Claim:
A set of material rolls for use in the process of cutting them, respectively, into specific-length pieces to be bonded to both sides of an optical display unit, comprising: 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 having an absorption axis parallel to the longitudinal direction of the long sheet material, 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 a short side of the optical display unit; and a second roll that is a roll of a long sheet material including a second optical film, a pressure-sensitive adhesive layer and a release film laminated in this order, wherein the second optical film includes a polarizing plate having an absorption axis parallel to the longitudinal direction of the long sheet material, 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 a long side of the optical display unit.
