Patent ID: 8002010

Claim:
A manufacturing system for an optical display device obtained by bonding an optical film including a polarizing plate or a retardation film and having the optical anisotropy in a direction of an absorption axis of the polarizing plate or a lagging axis of the retardation film to an optical display unit, comprising: a first cutting and bonding apparatus cutting a first optical film at a length corresponding to a long side of said optical display unit and thereafter bonding to one surface of the optical display unit, by using a roll around which a long sheet material having the first optical film having a width corresponding to a short side of said optical display unit is taken up; a second cutting and bonding apparatus cutting a second optical film at a length corresponding to a short side of said optical display unit and thereafter bonding to the other surface of the optical display unit, by using a roll around which a long sheet material having the second optical film having a width corresponding to a long side of said optical display unit and having the same direction for the optical anisotropy as said first optical film is taken up; and a feeder feeding the optical display unit after the first optical film is bonded, or the optical display unit after the second optical film is bonded, wherein said feeder is provided with a turning mechanism turning the optical display unit after being bonded by said first cutting and bonding apparatus in a bonding direction in said second cutting and bonding apparatus around a vertical direction to the surface of said optical display unit, or turning the optical display unit after being bonded by said second cutting and bonding apparatus in a bonding direction in said first cutting and bonding apparatus around a vertical direction to the surface of said optical display unit, and wherein said turning mechanism turns the optical display unit at such an angle that a direction of the long side of the optical display unit before being turned, and a direction of the long side of the optical display unit after being turned, form 85 degree to 95 degree.
