There are provided a system and a method for manufacturing an optical display device, in which optical films fed from two rolls which are the same in the direction of optical anisotropy, such as the direction of absorption axis, can be bonded to one and the other surfaces of an optical display unit so that the optical anisotropy of the one can be orthogonal to that of the other.The system includes: a first cutting and bonding apparatus 18 that is configured to handle a roll of a first sheet material F1 including a first optical film with a width corresponding to the short side of the optical display unit W and also configured to bond the first optical film to one surface of the optical display unit W and then to cut the first optical film into a length corresponding to the long side of the optical display unit W; and a second cutting and bonding apparatus 28 that is configured to handle a roll of a second sheet material F2 including a second optical film with a width corresponding to the long side of the optical display unit W and also configured to bond the second optical film to the other surface of the optical display unit W and then to cut the second optical film into a length corresponding to the short side of the optical display unit W.
