Abstract:
1. A set of material rolls, comprising: a first roll comprising a first optical film to be bonded to one surface of a rectangular optical display unit, the first roll comprising a first belt-shaped sheet material that comprises the first optical film, a first pressure-sensitive adhesive layer, and a first release film laminated in this order, wherein the first optical film comprises a first polarizing plate whose longitudinal direction is parallel to its absorption axis, the first belt-shaped sheet material having score lines that are previously formed so that the first optical film can be divided by the score lines into pieces each having a length corresponding to a long side of the optical display unit, the first belt-shaped sheet material having undergone a slitting process in a direction parallel to the longitudinal direction of the first polarizing plate so that it has a width corresponding to a short side of the optical display unit, and having been wound into the roll; and a second roll comprising a second optical film to be bonded to another surface of the optical display unit, the second roll comprising a second belt-shaped sheet material that comprises the second optical film, a second pressure-sensitive adhesive layer, and a second release film laminated in this order, wherein the second optical film comprises a second polarizing plate whose longitudinal direction is parallel to its absorption axis, the second belt-shaped sheet material having score lines that are previously formed so that the second optical film can be divided by the score lines into pieces each having a length corresponding to a short side of the optical display unit, the second belt-shaped sheet material having undergone a slitting process in a direction parallel to the longitudinal direction of the second polarizing plate so that it has a width corresponding to the long side of the optical display unit, and having been wound into the roll.
