Patent ID: 8398800

Claim:
A method for manufacturing an optical display device in which an optical film is bonded to an optical display unit, comprising: a bonding step of drawing a long sheet material having an optical film out from a roll on which the long sheet material is wound up, cutting at least the optical film into a predetermined length and, while feeding the long sheet material having the optical film cut, bonding the optical film cut onto one surface of the optical display unit that is successively fed; and a roll exchanging step of exchanging a roll of a previous category for a roll of a latter category and joining the optical films of the previous category and the latter category at the time of exchanging categories of the optical display unit, wherein the bonding step is stopped and the roll exchanging step is performed when the number X of remaining sheets of the optical display units of the previous category prior to bonding becomes substantially equal to the number N at the time of exchanging categories of the optical display unit, where N is the number of optical display units that may be bonded substantially in correspondence with the length of optical film that is present from a joining position of the optical film to a bonding position of the optical film.
