Patent number: 7086175Abstract: In a method of manufacturing a liquid crystal panel including a panel assembly, a nozzle mechanism is located at a vicinity of a liquid crystal filling port of the panel assembly with leaving a space between an intake of the nozzle mechanism and the liquid crystal filling port. The nozzle mechanism sucks surrounding gaseous to generate negative pressure and a continuous gaseous flow around the liquid crystal filling port. The negative pressure discharges an excess of liquid crystal filled in the panel assembly while the continuous gaseous flow blows the discharged liquid crystal. The blown liquid crystal is sucked into the intake of the panel assembly. Thus, a gap of the panel assembly is adjusted within a proper range in a short time.Type: GrantFiled: October 8, 2004Date of Patent: August 8, 2006Assignee: ANELVA CorporationInventors: Naoki Sasaki, Hideki Yoshizawa
