BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a syringe for a paste dispenser, and more particularly, to a syringe for a paste dispenser used for applying a liquid such as a sealant or a liquid crystal in a predetermined pattern in manufacturing a flat panel display panel.

In general, a flat panel display (FPD) is thinner and lighter than a television or a monitor using a cathode ray tube. As a flat panel display, a liquid crystal display (LCD), a plasma display panel (PDP), a field emission display (FED), an organic light emitting diode (OLED) .

Among them, the liquid crystal display is a display device capable of displaying a desired image by separately supplying data signals according to image information to liquid crystal cells arranged in a matrix form. Liquid crystal displays are thin, light, and have low power consumption and low operating voltage.

An example of a method of manufacturing a liquid crystal panel that is generally employed in such a liquid crystal display will be described below.

First, a color filter and a common electrode are pattern-formed on an upper glass substrate, and a thin film transistor (TFT) and a pixel electrode are pattern-formed on a lower glass substrate opposed to the upper glass substrate.

Subsequently, an alignment layer is applied to each of the substrates, and then the alignment layer is rubbed to provide a pretilt angle and an alignment direction in the liquid crystal molecules of the liquid crystal layer formed therebetween. In order to maintain the gap between the substrates and to prevent the liquid crystal from leaking to the outside and to seal between the substrates, a paste-like sealant is applied to one of the substrates by a dispenser device called a sealant applying device in a predetermined pattern .

Then, a liquid crystal layer is formed between the substrates, and then a liquid crystal panel is manufactured. At this time, there is a liquid dropping method as an example of a method of forming a liquid crystal layer. The liquid crystal dropping system is a system in which a liquid crystal is dropped by a dispenser device called a liquid crystal dropping device in a space defined by a sealant on a substrate to form a liquid crystal layer and then the substrates are bonded together with the liquid crystal layer interposed therebetween and the sealant is cured by bonding .

In manufacturing such a liquid crystal panel, a sealant is applied in a predetermined pattern or a coating operation for dropping liquid crystal is performed. Here, the coating operation is performed by controlling the air discharge pressure applied to the liquid so that the liquid can be discharged in a predetermined pattern from the nozzle, while moving the nozzle, which receives the liquid such as the sealant or the liquid crystal, from the syringe relative to the substrate do.

In order to remove such foreign matter, the operator manually removes the syringe body 20, the nozzle holder 30, and the upper cap 40 by using a cleaning liquid. At this time, the o- The airtightness between the syringe body 20 and the nozzle holder 30 and the upper cap 40 may be deteriorated. When the cleaning liquid contains harmful components, If the worker loses health or is seriously injured, it can be a life threatening hazard, and the possibility of influx of foreign matter upon washing may cause a deterioration of product quality.

In the case of using the syringe 10 for a paste dispenser made of a metal material in the production of the liquid crystal panel, the number of the o-rings 70 and 80 increases, so that it takes a lot of time to remove the foreign substances. Also, since the size of the O-rings 70 and 80 is generally small, it is inconvenient to manage such O-rings 70 and 80 frequently. In addition, when the syringe 10 for a paste dispenser is used for a long period of time, the O-rings 70 and 80 are often deformed due to repeated cleaning operations. As a result, the syringe body 20 and the nozzle holder 30, And the connection between the syringe body 20 and the nozzle holder 30 and the upper cap 40 may not be firm and the liquid or air may be leaked .
