  • Publication number: 20130168006
    Abstract: A method for manufacturing a liquid crystal display device includes the steps of: dropping a liquid crystal onto a substrate containing a smaller amount of adsorbed moisture, of a CF substrate and a TFT substrate; and after the step of dropping the liquid crystal, bonding the CF substrate and the TFT substrate together in a vacuum.

  • Patent number: 7656499
    Abstract: The invention relates to a method of manufacturing a liquid crystal display for which the one drop filling method is used to fill the gap between the substrates thereof and provides a method of manufacturing a liquid crystal display which can achieve high display characteristics. Droplets of a liquid crystal are dispensed in positions associated with exposure joint lines at boundaries between respective couples of adjoining regions to be exposed. Since this prevents stripe-like irregularities and grid-like irregularities from overlapping each other, display irregularities become less visually perceptible.

  • Patent number: 7553392
    Abstract: A method of manufacturing a liquid crystal display device in which liquid crystal is sealed between substrates using a one drop fill method. Dropping of liquid crystal is controlled so that the dropping quantity of the liquid crystal is reduced in an area including the vicinity of a seal material on a side with a relatively narrow cell gap width while the dropping quantity of the liquid crystal is increased in an area including the vicinity of the seal material on a side with a relatively broad cell gap width. Alternatively, dropping of the liquid crystal is controlled so that the number of times the liquid crystal is dropped is reduced in the area including the vicinity of the seal material on one side while the number of times the liquid crystal is dropped is increased in the area including the vicinity of the seal material on another side without changing the dropping quantity of one drop.

  • Patent number: 7216782
    Abstract: A dispenser has a syringe having a nozzle at one end thereof and a plunger fitted in the syringe from the other end of the syringe. One end of a pipe is connected to a portion of the syringe between the one end and the other end of the syringe. A liquid material tank is connected to the other end of the pipe. The liquid material tank is arranged so that a level of the liquid material in the liquid material tank is higher than in the syringe. The dispenser can be used for drip injection method for producing a liquid crystal display device to stably drip droplets of a liquid crystal onto a substrate of a liquid crystal display device.

  • Patent number: 6970227
    Abstract: A plurality of main seal patterns and dummy seal patterns are formed by a sealant on one of substrates. The plurality of main seal patterns individually enclose each of a plurality of display areas. The dummy seal patterns individually enclose the plurality of main seal patterns, and sides of the dummy seal patterns facing sides of the one substrate are all interconnected. These formations enable constant vacuum levels to be maintained the inside and the outside of the main seal patterns when the inside of a chamber of an assembling device is recovered to atmospheric pressure. Therefore, distortion of substrates is impeded in the vicinity of the main seal patterns, and degradation of display quality can be prevented.
