Abstract
Disclosed is a system for fabricating a liquid crystal display (LCD) using liquid crystal dropping (LC) and a method of fabricating an LCD using the same. The invention includes an LC forming line dropping LC on a first substrate, a sealant forming line forming sealant on a second substrate, a bonding and hardening line printing a sealant, bonding the substrates each other, and hardening the sealant, and an inspection process line cutting the bonded substrates into panel units and grinding and inspecting the unit panels. The present invention drops LC on a first substrate using a dispenser, forms a main UV hardening sealant on a second substrate, bonds the first and second substrates to each other in a vacuum state, UV-hardens the main UV hardening sealant, cuts the bonded substrates into cell units, grinds the cut substrates, and inspects the grinded substrates.
