法。1. In the polarizing film pasting method in which a polarizing film is pasted to the main body of a liquid crystal display element via adhesive, a chuck drum is fitted on the outside of a main body drum fixed to a support, and this chuck drum is attached to the main body drum. The chuck drum comprises a drum that can be rotated around a central axis by rotation, and a large number of small holes are provided throughout the circumferential surface of the chuck drum to reduce pressure in a space within a predetermined range of the circumferential surface of the main drum. Using a drum that can vacuum-adsorb the polarizing film through small holes in the chuck drum facing the reduced pressure space, the polarizing film is attached to a predetermined portion of the circumferential surface of the drum, and the space within the predetermined range is filled. In the step of sucking and holding the polarizing film by reducing the pressure, the end face portion of the polarizing film held by suction and the corresponding end face portion of the liquid crystal display element body are aligned and synchronized with the rotation of the circumferential surface of the drum. fixing the liquid crystal display element body on a movable table that moves by rotating the drum about the central axis;
Due to this rotation, the liquid crystal display element body on the movable table moves and enters between the circumferential surface of the drum and the movable table, and the polarizing film applies adhesive to the surface of the liquid crystal display element body due to the pressing force. The polarizing film has a pasting step in which the polarizing film is pasted through the liquid crystal display element body, and in this pasting step, the portions of the polarizing film that are successively pressed against the liquid crystal display element body are separated from the portions facing the reduced pressure space. Membrane attachment method.
