Method and system for continuously manufacturing liquid-crystal display element

摘要

The present invention provides a method for continuously manufacturing liquid-crystal display elements by laminating sheets of polarizing composite film (10) to respective ones of a plurality of liquid-crystal panels, the sheet being formed by cutting a continuous web of an optical film laminate having a width corresponding to a long or short side of the liquid crystal panel. The method comprises steps of; continuously feeding an optical film laminate (10), calculating a length measurement data based on the feed length of the optical film laminate, detecting a mark provided to the optical film laminate indicating defect information in a polarizing composite film being detected in a preliminary inspection, sequentially forming slit lines in a transverse direction with respect to the feed direction of the optical film laminate, determining the polarizing composite film sheet separated by the respective slit lines is a defective polarizing sheet or a normal polarizing sheet, peeling a sheet determined to be a normal polarizing sheet from the carrier film, and laminating the normal polarizing sheet to a respective one of liquid-crystal panel.
