摘要:
Provided are a system and a method for manufacturing an optical display device and a material roll, which can effectively prevent the production of defective optical display devices even in a process including drawing a long sheet material from a material roll and bonding an optical film to an optical display unit, and which is a roll of a laminate of a first base film, a first pressure-sensitive adhesive layer, an optical film, a second pressure-sensitive adhesive layer, and a second base film, which are wound in the roll in this order from the outside, and has a width corresponding to the length of any one side of a rectangular optical display unit, wherein the adhering strength A of the first base film-side interface of the first pressure-sensitive adhesive layer, the adhering strength B of the optical film-side interface of the first pressure-sensitive adhesive layer, the adhering strength C of the optical film-side interface of the second pressure-sensitive adhesive layer, and the adhering strength D of the second base film-side interface of the second pressure-sensitive adhesive layer satisfy the relations A
