BONDING DEVICE, BONDING METHOD, AND DISPLAY DEVICE PRODUCTION METHOD

Document Type and Number:

WIPO Patent Application WO/2020/246339

Kind Code:

A1

Abstract:

The present invention can pressurize an entire surface substantially uniformly, in a highly precisely positioned state.　A substantially planar first suction section suctions a substantially planar first member thereto, a substantially planar second suction section provided on the upper side, in the vertical direction, of the first suction section suctions a transparent and substantially planar second member thereto, and the two members are bonded together. The second suction section is a substantially tubular member having both ends thereof covered. The lower surface of the second suction section is a transparent suction pad having a throughhole formed therein that penetrates in the thickness direction. The second member is suctioned to the suction pad by air being drawn into the throughhole through a suction port. The surface on the upper side of the second suction section has at least part thereof formed from a transparent member. An imaging unit provided on the upper side of the second suction section in the vertical direction captures an image of the first member and/or the second member via the transparent member and the suction pad.
