APPARATUS FOR PRODUCING LIQUID CRYSTAL DISPLAY SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To produce liquid crystal display substrates which do not deteriorate display quality by intrusion of air bubbles into the liquid crystals in the substrates. SOLUTION: This apparatus for producing the liquid crystal display substrate 3 has a liquid crystal receiving tray 4 in which the liquid crystals 4A are packed, the liquid crystal display substrate 3 having a sealant which encloses the display region between the transparent substrates arranged to face each other and is provided with a liquid crystal sealing port and means for bringing the liquid crystal sealing port 24 of the liquid crystal display substrate 3 into contact with the surface of the liquid crystalsΔA of the liquid crystal receiving tray 4 in the atmosphere under a reduced pressure, then restoring the atm. pressure in the atmosphere. The apparatus has a shielding plate 5A arranged to cover at least the surface of the liquid crystals 4A in the liquid receiving tray 4 and a shielding plate releasing mechanism which releases the shielding of the surface of the liquid crystals 4A with this shielding plate 5A. The shielding plate releasing mechanism is constituted to release the shielding of the surface of the liquid crystals 4A at the time of bringing the liquid crystal sealing port 24 of the liquid crystal display substrate 3 into contact with the surface of the liquid crystals 4A of the liquid crystal receiving tray 4.
