ABSTRACT:
The present invention provides: a pressure plate used in a press for production of a liquid crystal panel, the plate being composed of an Si--SiC sintered material containing SiC and Si, and a process for producing a liquid crystal panel. The process includes sealing a liquid crystal in between a plurality of substrates and subjecting the resulting material to pressurization and heating by the use of a pair of the above pressure plates to bond the plurality of substrates. The process using the pressure plates can provide a liquid crystal panel which produces substantially no strain when heated, which has good gap accuracy between substrates, and which has a small surface roughness and high dimensional accuracy. Moreover, the process can produce a liquid crystal panel economically and in a smaller number of steps.
