Optical film cutting method and apparatus using the same

An optical film cutting method for cutting an optical film to obtain a sheet-like member, comprising:

• in a state that, in at least one of two nip rollers each including a pair of upper and lower rollers, the nip rollers being disposed on an upstream side and a downstream side of the strip-shaped optical film being transported with a portion to be cut of the optical film located therebetween in a transport direction, an axis of the upper roller is laterally displaced relative to an axis of the lower roller in a direction away from the portion to be cut,
• vertically moving one of the upper and lower rollers such that the rollers relatively approach each other to nip the optical film;
• cutting the optical film in a width direction in a state that opposed ends of the optical film are nipped by the nip rollers;
• and
• vertically moving one of the upper and lower rollers such that the rollers are relatively separated from each other to cancel the nip of the optical film by the nip rollers, after cutting the optical film.
