Abstract:
1. A roll of optical film laminate adapted for use in a continuous manufacturing system for liquid-crystal display elements, wherein the manufacturing system is operative to produce liquid-crystal display elements by adhesively attaching a polarizer to each of the opposite surfaces of a liquid crystal panel which is of a rectangular shape having a long side dimension and a short side dimension, the roll of optical film laminate comprising a continuous web of optical film, the continuous web of optical film comprising: a polarizing composite film which includes: said continuous web of optical film having a longitudinal direction and a transverse direction which is perpendicular to said longitudinal direction, and further having a width corresponding to one of said long or short side dimension; a carrier film being laminated in a releasable manner to the adhesive layer of the polarizing composite film, wherein the polarizing composite film has a plurality of predefined slit positions for determining positions of slit lines each extending in said transverse direction throughout the width of said web of optical film to define rectangular regions each between two longitudinally adjacent slitting positions, said rectangular regions including defective regions and defect-free, normal regions, which have been defined based on locations of defects existing in the polarizing composite film and detected previously by inspection, the defect-free, normal regions each having a longitudinal dimension corresponding to the other of said long or short side dimension of the liquid crystal panel, the continuous web of optical film having encoded information recorded thereon, the encoded information including slit position information for specifying positions at which the respective slit lines are to be formed in the continuous web of optical film by a slitting unit of the continuous manufacturing system, based on the defective regions and the normal regions of the polarizing composite film, the encoded information being readable by a reading unit of the continuous manufacturing system.
