Abstract
An apparatus for manufacturing a liquid crystal panel in which two substrates are faced to each other with spacers interposed therebetween, applied with heat and pressure in an overlapped condition, and adhesive arranged between two substrates is cured for fixing, characterized in that at least one of a pair of pressurizing plates for applying pressure to the two substrates is a graphite plate and in that upper and lower pressurizing plates are made to be of different rigidity. The graphite plate of low rigidity is made to stick to the substrate, and shifts between substrates can be prevented while securing uniformity in gaps between substrates.
