Abstract
A method for continuously manufacturing liquid-crystal display elements includes steps of; continuously feeding an optical film laminate, 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.
