Abstract
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, includes a polarizing film supply step including drawing an optical film laminate from the continuous roll placed in a dry environment, cutting at least a polarizing film and a pressure-sensitive adhesive, while leaving a carrier film uncut and feeding the sheet piece and the pressure-sensitive adhesive piece; a liquid crystal panel supply step including 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 including 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.
