It comprises a supply conduit 39 for supplying air into the interior, and a valve 40 provided in the middle of the supply conduit 39. The valve 40 is closed, the valve 37 is opened, and the vacuum pump 38 is operated to evacuate the vacuum chamber 20 so that the vacuum chamber 20 can be depressurized. Further, the valve 37 is closed and the valve 40 is opened, so that air flows into the vacuum chamber 20 through the supply pipeline 39, and the vacuum chamber 20 is closed.
The inside can be returned from the reduced pressure state to the atmospheric pressure state. With this configuration, the atmosphere in the vacuum chamber 20 can be set to a predetermined degree of vacuum (reduced pressure state).

The liquid crystal injection port 10 of the panel P and the jet port 23 are in contact with each other. Pump 35 into the first container 21.
Thus, the liquid crystal is sent in, and the liquid crystal 22 that cannot be contained in the first container 21 flows out from the jet port 23. Among the liquid crystals jetted from the jet port 23, the liquid crystals that are not injected into the strip panel P in the empty cell state flow into the second container 24. The liquid crystal 25 in the second container 24 passes through the circulation path 41, is filtered by passing through the filter 34, and is again flowed into the first container 22. The filter 34 filters foreign substances such as glass powder and dust mixed in the liquid crystal 25. As described above, in the present embodiment, the liquid crystal that has not been injected into the cell is reused, so that the material efficiency is high.

On the other hand, based on the information sent from the sensor 26b, when the control device 27 determines that the water level on the liquid surface is higher than the predetermined value, the valve 33 is closed, the operation of the pump 32 is stopped, and the new liquid crystal is stopped. The replenishment of 30 is stopped. With such a configuration, new liquid crystal can be automatically replenished.

Next, a liquid crystal injection process using the above-mentioned injection device will be described with reference to FIGS. Figure 2
It is a figure for demonstrating operation | movement of the injection apparatus and the state of a strip panel in a liquid crystal injection process. FIG. 3 is a schematic diagram of the injection device in each step, and in FIG. 3, only the main configuration at each step is shown.

As shown in FIGS. 2 and 3 (a), the strip panel P in the empty cell state is carried into the vacuum chamber 20 of the injecting apparatus 1, and the strip panel P is arranged at a predetermined position. The strip panel P is arranged so that the liquid crystal inlet 10 and the jet port 23 of the first container 21 corresponding to each liquid crystal inlet are in contact with each other. Next, the valve 37 is opened, and the vacuum pump 38
Is operated to evacuate the inside of the vacuum chamber 20 to sufficiently evacuate the cells of the strip panel P to reduce the pressure inside the vacuum chamber including the cells. Incidentally, for example, the liquid crystal injection port 10
And the shape of the jet port 23 are substantially similar to each other, and the jet port 23 is larger than the liquid crystal injection port 10.

Next, as shown in FIGS. 2 and 3 (b),
First, the pump 35 is operated to send the liquid crystal to the first container 21, and the liquid crystal 22 is jetted from the jet port 23 of the first container 21 so that the liquid crystal 22 is in contact with the liquid crystal inlet 10. . After that, the valve 37 is closed, the valve 40 is opened, and air is flown into the vacuum chamber 20 through the supply conduit 39 to return the vacuum chamber 20 to the atmospheric pressure state.
As a result, the liquid crystal 22 flowing out from the jet port 23 is injected into the cell of the strip panel P via the liquid crystal injection port 10 due to the pressure difference between the inside and the outside of the cell. Further, since the pressure is changed while the liquid crystal 22 is constantly in contact with the liquid crystal inlet 10,
Air does not enter the liquid crystal.

After the liquid crystal is injected into the entire area of the cell, the strip panel P'injected with the liquid crystal is carried out as shown in FIG.

As described above, in the present embodiment, the liquid crystal is injected into the empty cell by jetting the liquid crystal from the jet port corresponding to the liquid crystal injection port without immersing the substrate end portion of the empty cell in the liquid crystal. Therefore, the liquid crystal adhesion range at the edge of the substrate can be greatly reduced as compared with the conventional case. Therefore,
The amount of liquid crystal used can be reduced, and the liquid crystal utilization efficiency is improved. Further, the liquid crystal can be easily wiped off and cleaned.

Further, in this embodiment, the empty cell is not soaked in the liquid crystal in the liquid tank as in the conventional case,
The liquid crystal in the first container is always in a good condition without being contaminated by dust attached to the empty cells. Therefore, it is possible to obtain a liquid crystal panel in which liquid crystal free from contamination is injected. When such a liquid crystal panel is incorporated in a liquid crystal device, a problem such as display unevenness due to contaminated liquid crystal does not occur, and a liquid crystal device having stable quality characteristics can always be obtained.

In addition, in the conventional injecting apparatus, a moving mechanism for moving the cell up and down is required in order to immerse the empty cell in the liquid crystal in the liquid tank and, after injecting, to pull up the cell in which the liquid crystal is injected from the liquid tank. However, in the injection device according to the present embodiment, since the liquid crystal is jetted, it is not necessary to provide a conventional moving mechanism.

Further, in the present embodiment, the panel shape to be carried into the injection device is in a multi-cavity form, but it may be a single panel. Further, in the present embodiment, the case where one panel is loaded into the injection device has been described as an example, but it goes without saying that a configuration in which a plurality of panels are loaded and processed simultaneously is also possible.
