ABSTRACT:
A system for manufacturing an optical display device having an optical display unit and an optical film bonded thereto and including a polarizing plate, the system including: a first cutting and bonding unit which performs a process including unwinding a long sheet material from a first roll of the long sheet material, wherein the long sheet material includes a first optical film, a pressure-sensitive adhesive layer and a release film laminated in this order; a second cutting and bonding unit which performs a process including unwinding a long sheet material from a second roll of the long sheet material, wherein the long sheet material includes a second optical film, a pressure-sensitive adhesive layer and a release film laminated in this order; and a turning unit which turns the optical display unit to the direction of bonding in the other cutting and bonding unit.
