Abstract:
1. A method for manufacturing a liquid crystal display element, comprising: providing a long sheet material including a laminate of an optical film containing a polarizer, a pressure-sensitive adhesive layer, and a carrier film temporarily bonded to the pressure-sensitive adhesive layer; cutting the long sheet material at predetermined intervals, while maintaining the continuity of the carrier film; peeling off the carrier film by a tensile force; and continuously bonding the resulting optical film pieces to liquid crystal panels, respectively, through the pressure-sensitive adhesive layer exposed by the peeling off, while feeding the resulting optical film pieces, wherein the cutting is performed to such a depth as to substantially reach the carrier film while moving a cutting blade in the width direction of the carrier film, so that a depth at some portion is not less than half of the thickness of the carrier film and the carrier film is cut to a depth less than half of the thickness of the carrier film at at least both end portions in the width direction of the carrier film.
