ABSTRACT:
A method of manufacturing a liquid crystal panel includes the steps of adjusting mutual positions of a pair of substrates, applying a pressure onto a sealing material made of a ultraviolet-curing resin applied onto the substrates, and hardening a predetermined temporal combining area of the sealing material by emitting a UV ray to be incident thereon. The resulting temporary fixed substrate is placed on a stage of a final hardening press device, and an embossed sheet having fine protrusions and recessions uniformly formed on a surface thereof is lowered to be superimposed onto the temporary fixed substrate. Further, by applying a vacuum suction to a sealed space between the stage and the embossed sheet, the entire surface of the temporary fixed substrate is pressurized under an atmospheric pressure to form a uniform cell gap as desired. Thereafter, a UV ray is applied by a UV lamp to finally harden the sealing material. As a result, a liquid crystal panel having an excellent positioning precision and a cell gap precision can be manufactured at high yield.
