Abstract
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.
