Abstract
A method for continuously manufacturing an optical display device comprises feeding a continuous web of optical film laminate including a continuous web of releasable film that includes a conductive layer and an optical film sheet that includes a conductive layer formed on the releasable film, bending the releasable film at a peeling body located in close vicinity of a lamination position, collecting the releasable film and thereby peeling the optical film sheet from the optical film laminate, sending the optical film sheet to the lamination position, and laminating the optical film sheet with a panel member which is conveyed to the lamination position by a panel conveying channel which makes at least a double-storied structure with a portion of a collecting channel where the releasable film is collected, attenuating static electrification generated on the optical film sheet, and continuously laminating the optical film sheet with the panel member.
