Abstract
An adhesive-film exfoliating device includes an absorption stagefor absorbing a liquid crystal display panelin which a polarizing plateis adhered to a glass plate, a clamping unitfor clamping a cornerof the polarizing plateexfoliated from the glass plateand a ball screw shaftfor moving the absorption stagerelatively to the clamping unit. A ball screw nutin screw-engagement with the ball screw shaftis fixed on a back surface of the absorption stage. With the rotation of the ball screw shaft, the absorption stageintegral with the ball screw nutis slid in a direction to exfoliate the polarizing plateexfoliated from the glass plate. In a manufacturing method of the liquid crystal display panel, a process of exfoliating the polarizing platefrom the glass plateincludes steps of moving the absorption stagewhile allowing the clamping unitto clamp the cornerof the polarizing plate
