Method and system for manufacturing liquid crystal display device

A method for manufacturing a liquid crystal display device by feeding long carrier films from continuous rolls, respectively, wherein the continuous rolls comprise rolls of laminates comprising the long carrier films and pressure-sensitive adhesive carrying optical films each with a specific width placed on the carrier films, respectively, and by bonding the optical films, which are being peeled off or have been peeled off from the carrier films, respectively, to first and second panel surfaces of a liquid crystal panel, respectively, with the pressure-sensitive adhesive interposed therebetween so that the liquid crystal display device is obtained, the method comprising:

• a first bonding step comprising bonding a first optical film to the first panel surface of the liquid crystal panel, wherein the first optical film has a transmission axis in its widthwise direction;
• then
• a rotation step comprising rotating by 90° the liquid crystal panel with the first optical film bonded to the first panel surface;
• then
• a second bonding step comprising bonding a second optical film to the first optical film on the first panel surface, wherein the second optical film has a transmission axis in a direction perpendicular to its widthwise direction and the transmission axis of the first optical film is parallel with the transmission axis of the second optical film and wherein the second optical film is bonded so that the transmission axis of the second optical film is parallel to the transmission axis of first optical film;
• and then
• a third bonding step comprising bonding a third optical film to the second panel surface of the liquid crystal panel with the first and second optical films bonded to the first panel surface, wherein the third optical film has a transmission axis in its widthwise direction and the transmission axis of the third optical film is perpendicular to the transmission axis of the first optical film and the second optical film.
