[0033] figure 1 It is explanatory drawing of the bonding apparatus A which concerns on one Embodiment of this invention. The bonding apparatus A is an apparatus for bonding two panels together to manufacture a laminate. In the case of this embodiment, the laminated body which bonded together the square panel and the square panel is manufactured. One panel is, for example, an image display panel, and the other panel is, for example, a cover panel, and this laminate constitutes an image display device. The image display panel is, for example, a liquid crystal display panel (such as LCD), and a cover panel (such as a glass cover) is attached to the display surface side (upper surface in the lamination process). The cover panel is a light-transmitting panel, for example, a glass plate or a resin plate.

[0034] An adhesive layer is formed in advance on at least one of the two panels to be bonded, and the two panels can be bonded together by this adhesive layer. The ...

[0100] In the first embodiment, the middle region RM is swollen by the elastic deformation of the sheet member 13 , but a configuration in which the middle region RM is bulged by the displacement of the movable member may also be adopted. A structural example thereof will be described below.

[0101] Figure 12 (A) and Figure 12 (B) is an explanatory diagram of a holding unit 1A replacing the holding unit 1 of the first embodiment. In the following description and drawings, the same reference numerals are attached to the same or similar structures as those of the holding unit 1 among the structures of the holding unit 1A. Therefore, the following description will focus on the differences between the holding unit 1 and the holding unit 1A. In general, the holding unit 1A is provided with a movable member 15 instead of the sheet member 13 .

Abstract

The object of the present invention is to hold the panel more reliably and prevent the mixing of air bubbles. It is a holding unit that holds one of the panels that are bonded to each other. The support member supports a contact portion that is in contact with the panel, and the contact portion includes a plurality of openings and an intermediate region that can bulge toward the panel side at a position corresponding to the central portion of the panel, and the plurality of air supply and exhaust The path includes a first air supply and exhaust path communicating with the plurality of openings and a second air supply and exhaust path open to the middle area, and the middle area can utilize the inside of the second air supply and exhaust path. A differential pressure with the surrounding atmosphere of the contact portion expands from the support member.

Description

technical field [0001] The invention relates to the pasting technology of panels. Background technique [0002] In an apparatus for manufacturing a laminate by bonding panels such as a liquid crystal panel and a cover glass, if air bubbles are mixed in the bonding surface, the quality of the laminate may be affected. In order to reduce the entrainment of air bubbles, Patent Document 1 and Patent Document 2 disclose devices in which one panel is bent and brought into contact with the other panel. In these devices, the air bubbles between the panels can be squeezed out to the surroundings, which has a certain effect on preventing the mixing of air bubbles.
