Abstract
Provided is a system for manufacturing a display unit, the system including: a carrying unit which carries an optical film including a polarizing film including an adhesive layer and a release film to which the polarizing film is bonded to be peeled off through the adhesive layer; a cutting unit which cuts the optical film by a predetermined depth, in which the release film is not cut, and forms a polarizing film sheet piece on the optical film; a peeling unit which peels the polarizing film sheet piece from the release film; and an attachment unit which attaches the polarizing film sheet piece peeled from the release film to a panel, in which the attachment unit includes: a pair of attachment rolls which presses and attaches the polarizing film sheet piece onto one surface of the panel; and a magnetic force generating unit or a suction part, which suppresses an upper attachment roll positioned at an upper side between the pair of attachment rolls from sagging by using magnetic force or suction.
