The invention relates to system for attaching a film and a method for attaching a film. The system for attaching the film includes: a first polarization film attaching system and a second polarization film attaching system. The first polarization film attaching system includes: a panel delivering part for delivering the panel to a first polarization film attaching area, a film supply part for supplying a first polarization film unit, a cutter for fully cutting the first polarization film unit delivered by the film delivering part, a first adsorption drum, and a release paper removing part. The first polarization film unit fully cut by the cutter is revolved by a pre-setting angle taking a vertical axis as the center before reaching the first film attaching area. In the first polarization film attaching area, the first adsorption drum rotates, and the panel moves, so that the first polarization film contacted with the surface of the first adsorption drum is attached to the first surface of the panel.
