A production layout for an LCD is provided. The production layout for an LCD includes a bonding part operable to bond a pair of substrates for the LCD with a sealant and a hardening part operable to harden the sealant. The hardening part includes an ion provider operable to supply ions to the substrates during a hardening process of the sealant. The production layout further includes a transfer unit that loads and unloads the bonded substrates. Footprint and tact time for manufacturing the LCD may be reduced. Electrostatic removal effect of the bonded substrates may improve.

Production layout for LCD, method for manufacturing the LCD, and hardening device for the LCD

An LCD device and a method for manufacturing the same is disclosed, in which it is possible to correct a problem of insufficient or excessive supply of liquid crystal in an LCD device by controlling an amount of liquid crystal. The method includes preparing a liquid crystal cell comprised of a first substrate, a second substrate, a liquid crystal layer between the first and second substrates, and a first sealant formed in the periphery of the liquid crystal layer between the first and second substrates; measuring an amount of liquid crystal provided to the inside of liquid crystal cell; forming an inlet for liquid crystal in the first sealant; and regulating the amount of liquid crystal by supplying or discharging the liquid crystal through the inlet; and sealing the inlet.

Methods of manufacturing liquid crystal display devices

An inspection apparatus and inspection method for liquid crystal display devices are disclosed, wherein a final inspection for completely manufactured liquid crystal display devices is performed using a visual-light inspection apparatus, whereby high productivity due to improved inspection accuracy and reduced inspection time can be accomplished. With the inspection apparatus and inspection method, defects of a plurality of glass panels can be automatically inspected based on analyzed information of an entire screen of each glass panel using a plurality of vision cameras, whereby improved inspection accuracy and improved product quality can be accomplished and reduced inspection time can result in improved productivity of liquid crystal display devices. Further, by quantifying screen defects of the plurality of glass panels, defects of glass panels due to failures of manufacturing processes or design failures and other problems attendant on the defects can be prevented.

A heat curing device includes supports positioned in a chamber to support a substrate, the supports having sections, and protrusion structures formed on the sections of the supports to contact a dummy area of the substrate, wherein the supports may be rotated with respect to a horizontal axis. The sections of the supports may have a polygonal structure with the protrusion structures are formed on the polygonal sections of the supports, so that a plurality of protrusion structure patterns can be formed on one support. Since the supports are rotatable, the protrusion structure patterns supporting a substrate may be readily changed.

Heat curing device and method of fabricating liquid crystal display device using the same

A method for manufacturing a liquid crystal display device includes preparing a lower substrate and an upper substrate; depositing a sealant on one of the two substrates; dropping a liquid crystal on one of the two substrates; bonding the two substrates to each other; bonding the two substrates to each other by hardening the sealant; and thermal quenching the two bonded substrates. Since thermal quenching of the two bonded substrates is additionally performed after hardening of the sealant is performed using a liquid crystal dropping method, orientation of a liquid crystal layer, which is scattered by the hardening of the sealant, is returned to its original state, thus preventing domain defects.
