OPTICAL FILM LAMINATE WITH A CONTINUOUS WEB OF CUTTING LINES AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS THEREOF

摘要

Provided is an optical film laminate with cutting lines for increasing the precision and speed in the manufacture of liquid crystal elements and drastically improving the yield. The optical film laminate with a continuous web of cutting lines is assumed to be used in an apparatus which continuously manufactures liquid crystal display elements affixed with a sheet of optical functional film. The optical film laminate is divided in the lengthwise direction based on the positions of detected defects and is composed of regions which do not include defects having the specified lengths corresponding to the dimensions of the liquid crystal panel and regions which include defects having different specified lengths than the region not including defects. In the optical film laminate which includes an optical functional film including an adhesive layer and a carrier film which can be peeled off and is deposited on the adhesive layer, a normal sheet which does not include defects in the carrier film and a bad sheet which includes defects are formed by forming cutting lines corresponding to each of the above regions along the width direction of the optical film laminate.
