Abstract: A method of continuously manufacturing a display unit according to an exemplary embodiment of the present invention, which bonds sheet pieces of a polarizing film formed by cutting a roll-type optical film into sheet pieces having a predetermined sheet pieces to a panel to manufacture the display unit, continuously carries an optical film, detects a defect of the optical film, extracts a defective area based on information on the detected defect, forms a slit line in a horizontal direction with respect to a carrying direction of the optical film based on the defective area, determines whether the sheet piece of the polarizing film divided by the slit line is a defective sheet piece or a normal sheet piece, peels the sheet piece determined as a normal sheet piece from a release film, and bonds the normal sheet piece and a panel.

Abstract: The present invention relates to a peeling bar, apparatus, and method for peeling a polarizing film from a panel. This invention can minimize friction between the peeling bar and the polarizing film since the peeled polarizing film is in contact with a tip of a front part of the peeling bar. The radius of a curved surface at the tip of the front part and an inclined upper surface of the front part are designed to minimize the Z-axis component of a shearing force applied to the polarizing film. Also, in order to equalize tension applied to the polarizing film in a peeling process, this invention makes both ends of the polarizing film closely adhere to the peeling bar.According to this invention, fracture of the polarizing film is prevented, and thereby the polarizing film can be stably peeled from the panel without fracture.
