Method and system for continuously manufacturing liquid crystal display device

A method for continuously manufacturing a liquid crystal display device by bonding a polarizing film to a liquid crystal panel with a pressure-sensitive adhesive interposed therebetween, comprising:

• a polarizing film supply step comprising drawing an optical film laminate from a continuous roll placed in a dry environment, wherein the continuous roll comprises a roll of an optical film laminate comprising at least a long polarizing film having a width corresponding to a width of the liquid crystal panel and a carrier film placed on the polarizing film with a pressure-sensitive adhesive interposed therebetween, cutting at least the polarizing film and the pressure-sensitive adhesive at predetermined intervals, while leaving the carrier film uncut, so that a sheet piece of the polarizing film and a pressure-sensitive adhesive piece are obtained, and feeding the sheet piece and the pressure-sensitive adhesive piece which are placed on the carrier film;
• a liquid crystal panel supply step comprising feeding the liquid crystal panel in a first humid environment having a relative humidity higher than that of the dry environment;
• and
• a bonding step comprising bonding the sheet piece to the liquid crystal panel with the pressure-sensitive adhesive piece interposed therebetween in a second humid environment having a relative humidity higher than that of the dry environment, wherein the sheet piece is fed by the polarizing, film supply step, and the liquid crystal panel is fed by the liquid crystal panel supply step.
