  • Patent number: 8031321
    Abstract: An LCD device and a method for manufacturing the same is disclosed, in which it is possible to correct a problem of insufficient or excessive supply of liquid crystal in an LCD device by controlling an amount of liquid crystal. The method includes preparing a liquid crystal cell comprised of a first substrate, a second substrate, a liquid crystal layer between the first and second substrates, and a first sealant formed in the periphery of the liquid crystal layer between the first and second substrates; measuring an amount of liquid crystal provided to the inside of liquid crystal cell; forming an inlet for liquid crystal in the first sealant; and regulating the amount of liquid crystal by supplying or discharging the liquid crystal through the inlet; and sealing the inlet.

  • Patent number: 7884893
    Abstract: Disclosed is a method of testing a liquid crystal display device enabling a quick test by determining a test of a liquid crystal panel according to a liquid crystal filling state of the liquid crystal panel. The method includes: checking a liquid crystal filling state of a liquid crystal panel for a defective liquid crystal filling state; and executing a test of a liquid crystal panel having a defective liquid crystal filling state. The process for testing a liquid crystal filling state may include detecting a dispensed amount of liquid crystal dropped using a liquid crystal dispensing apparatus or may include measuring the weight of liquid crystal dropped. Other methods of identifying the filling state of the liquid crystal panel may be used.
