Patent ID: 8083885

Claim:
A method for manufacturing an optical display device comprising an optical film including a polarizing plate and a rectangular optical display unit having a surface to which the optical film is bonded, the method comprising the steps of: providing a long material comprising an optical film including a polarizing plate, the long material having a longitudinal direction parallel to an absorption axis of the polarizing plate; lengthwise slitting the long material parallel to the absorption axis so as to produce a long sheet material having a width corresponding to a short or long side of the optical display unit winding the long sheet material produced by the lengthwise slitting into a material roll; and unwinding the long sheet material from the material roll, cutting at least the optical film of the long sheet material to form an optical film having a length corresponding to a long or short side of the optical display unit, and then bonding the optical film to a surface of the optical display unit.
