Abstract:
1. A method for fabricating a liquid crystal display (LCD), comprising: loading a first substrate having liquid crystal dispensed thereon onto an upper surface of a lower stage within a bonding chamber; holding a second substrate having sealant coated thereon to a lower surface of an upper stage within the bonding chamber, wherein the upper stage has at least one vacuum channel and wherein loading the second substrate includes evacuating the at least one vacuum channel such that the second substrate is held to the lower surface of the upper stage by vacuum suction; after holding the second substrate to the lower surface of the upper stage by vacuum suction, electrostatically holding the second substrate to the lower surface of the upper stage; performing a first evacuation of the bonding chamber at a first evacuation rate; performing a second evacuation of the bonding chamber at a second evacuation rate, wherein the second evacuation rate is less than the first evacuation rate; bonding the first and second substrates within the evacuated bonding chamber; and unloading the bonded first and second substrates from the bonding chamber.
