Exemplary embodiments of the present invention provide an optical film attachment system which is connected to a downstream device and includes a panel conveyance path, the optical film attachment system including: a connection unit which connects the panel conveyance path and the downstream device and conveys the panel; a first inspection unit which is positioned on the panel conveyance path and finds out whether the panel with the attached optical film has a defect; and a second inspection unit which is positioned at a position spaced apart from the panel conveyance path and re-inspects a defect-determined panel determined as a defective panel by inspection by the first inspection unit; in which the connection unit includes a main conveyance path in which a first conveyance unit and a second conveyance unit are sequentially arranged in a conveyance direction of the panel conveyance path, a first auxiliary conveyance path which connects the first conveyance unit and the second inspection unit and is bypassed from the main conveyance path, and a second auxiliary conveyance path which is connected to the second conveyance unit and bypassed from the main conveyance path, the control unit controls the connection unit so that the defect-determined panel is conveyed from the first conveyance unit to the second inspection unit along the first auxiliary conveyance path when the panel inspected by the first inspection unit is determined as a defective panel, and a good-quality-determined panel determined as a good-quality panel by the first inspection unit is conveyed from the second conveyance unit along the second auxiliary conveyance path when it is difficult to convey the good-quality-determined panel to the downstream device.

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 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.
