In-line system and a method for manufacturing a liquid crystal display

Abstract

Disclosed is an in-line system and a method for manufacturing a liquid crystal display. The system includes a spacer-dispersing unit for dispersing spacers on one of two substrates of a mother glass, the mother glass having at least one liquid crystal cell; a sealant-applying unit for depositing a sealant on one of the two substrates; a liquid crystal depositing unit for depositing liquid crystal material on the substrate on which the sealant is deposited; and a substrate-attaching unit for receiving the two substrates from the sealant-applying unit or the liquid crystal depositing unit, then conjoining the substrates in a vacuum state. The method includes the steps of dispersing spacers on one of two substrates of a mother glass, the mother glass having at least one liquid crystal cell; depositing sealant on one of the two substrates; depositing liquid crystal material on the substrate where the sealant is deposited; and conjoining the substrates in a vacuum state to complete the manufacture of a liquid crystal panel.
