Abstract:
1. A substrate assembly apparatus to bond a lower substrate and an upper substrate together, the lower substrate including a panel forming section, onto which a liquid crystal is dropped, both substrates being vertically and opposingly held in position, positioned relative to each other and brought together to allow a gap therebetween, and bonded together within a depressurized chamber, the apparatus comprising: an upper frame; an upper chamber forming part of the chamber divided vertically into two, the upper chamber being supported by the upper frame and including thereinside an upper table to hold the upper substrate; a lower chamber disposed on a mount, the lower chamber having a lower table to hold the lower substrate; and drive means for moving the upper frame vertically, disposed at four corners of the mount, wherein the upper chamber is coupled to the upper frame through a joint; wherein the upper frame includes an upper shaft for supporting the upper table disposed in the upper chamber; and when the upper chamber and the lower chamber are united to form a chamber, the joint between the upper chamber and the upper frame is disengaged so as to allow only the upper table coupled to the upper frame to be moved vertically.
