A set of material rolls is used for 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.
A method for producing a material roll for use in the process of cutting it into a specific-length piece to be bonded to a surface of an optical display unit, comprising the steps of:
