Abstract:
1. A substrate assembling apparatus in which one substrate with drops of liquid crystal is held on a lower table and another substrate is held on an upper table, facing the one substrate, and the substrates are laminated in a vacuum chamber using an adhesive agent provided on either of the substrates, wherein the upper table inside the chamber includes, on its substrate holding face, an elastic plate including an elastic body, a vacuum suction means and a purge gas blow means; a plurality of adhesive pins are provided on an adhesive pin plate, located adjacent to the upper table, which can move up and down independently from the upper table; the upper table and the elastic plate include through holes through which the adhesive pins can move to contact said another substrate; and the adhesive pins include adhesion means at their tips to hold said another substrate, wherein each adhesive pin includes an adhesive member on its tip and a suction/adsorption hole in the center of the tip to permit either negative or positive pressure to be applied to said another substrate through said suction/adsorption hole.
