System and method for manufacturing optical display element

A method of manufacturing an optical display element by laminating an optical film on a surface of a rectangular organic light emitting display panel, the method comprising:

• supplying an organic light emitting display panel;
• conveying the organic light emitting display panel;
• preparing a plurality of raw optical film rolls by slitting a raw optical film in a longitudinal direction by a predetermined slitting width before processing to form n raw optical films, wherein n is an integer greater than 1, and wherein the slitting width is a width corresponding to an edge having a smaller remainder after dividing a width of the raw optical film before processing by a length of a long edge and a length of a short edge of the organic light emitting display panel and deriving integer quotients thereof;
• supplying an optical film by unwinding the optical film from one of the raw optical film rolls;
• laminating the optical film on the surface of the organic light emitting display panel;
• and
• rotating the organic light emitting display panel by 90° when a width-directional edge of the organic light emitting display panel as supplied does not correspond to a width of the one of the raw optical film rolls before the optical film is laminated on one surface of the organic light emitting display panel.
