BACKGROUND ART [0002] With the development of an information-oriented society, it is required to develop a technique for a video display device which improves disadvantages such as a heavy weight and a large volume of a conventional CRT (Cathode Ray Tube).

Accordingly, various flat panel display devices such as OLED (Organic Light Emitting Diode), PDP (Plasma Panel Display Device) and SED (Surface-conduction Electron-emitter Display Device) .

Among the various flat panel display devices, LCD (Liquid Crystal Display Device) which is widely used from a display screen of a small mobile phone to a large TV screen is the most typical flat panel display device.

In general, a method of forming a liquid crystal display device includes a liquid crystal injection method in which liquid crystal is injected using a pressure between two substrates after laminating two substrates, a liquid crystal injection method in which a liquid crystal is dropped onto one of two substrates, There are two methods of dropping the liquid crystal.

Among the above two methods, a liquid crystal display device is manufactured by adopting a more efficient method in consideration of characteristics of a product to be produced.

For example, in the case of producing a small-sized liquid crystal display device used for a small-sized mobile phone or navigation, it takes a lot of time to drop liquid crystal individually on each substrate. Therefore, A liquid crystal injection method which can be used is mainly applied.

On the other hand, when a middle- or large-sized liquid crystal display device used for a monitor of a desktop PC or a large-sized TV screen is produced, it takes much time to inject liquid crystal on a large substrate, so a liquid crystal dropping method is mainly applied.

Among them, in the case of producing a liquid crystal display device by a liquid crystal dropping method, a liquid crystal dispensing device capable of moving the upper part of the substrate and dropping liquid crystal is required in order to drop liquid crystal on the substrate.

1, the liquid crystal dispensing apparatus includes a liquid crystal container holding device 120 for holding a liquid crystal container 110 in which liquid crystal is received, A block 140 connected to the dispenser unit 130 for moving the dispenser unit 130 in a vertical direction A relative to a substrate (not shown) And a sliding part 142 and a guide rail 144 connected to the block part 140 to move the block part 140 in the left and right directions B, respectively.

The liquid crystal container holding apparatus 120 has a block shape having a concave portion on one surface thereof, and the liquid crystal container 110 is inserted and fixed to the concave portion.

The dispenser unit 130 includes a discharge pump (not shown) for sucking liquid crystal from the liquid crystal container 110. The liquid crystal sucked by the discharge pump is dropped onto the substrate through the discharge nozzle 132.

The block unit 140 is connected to and supports the liquid crystal container holding apparatus 120 and the dispenser unit 130 and moves the dispenser unit 130 in a vertical direction A with respect to a substrate The distance between the substrate and the discharge nozzle 132 is adjusted to prevent the discharge nozzle from being damaged by the substrate and preventing the liquid crystal from being accumulated.
