When the strip panel P is housed in the panel holding portion 220, the inlet 10 is exposed to the hollow.

As shown in FIGS. 10 to 12, the liquid crystal supply unit 210 has a base 213 and three bases 213 provided on the base 213.
It has two liquid crystal injection nozzle bases 211. The liquid crystal supply unit 210 is connected to the moving mechanism 202 via a shaft 207, and the movement of the moving mechanism 202 causes the liquid crystal supply unit 210 to move to y.

Further, each liquid crystal injection nozzle base 211 is provided with nine liquid crystal injection nozzles (described later). The longitudinal direction of the liquid crystal injection nozzle base 211 and the longitudinal direction of the strip panel P are substantially orthogonal to each other, and in the present embodiment,
Since one strip panel P has three inlets 10, three liquid crystal injection nozzle bases 211 are provided. Further, in the present embodiment, since nine strip panels P are arranged, each liquid crystal injection nozzle base 211 is provided with nine liquid crystal injection nozzles. Each liquid crystal injection nozzle base 211
The liquid crystal 233 stored in the liquid crystal reservoir 234 is supplied to the liquid crystal flow path (described later) provided in the liquid crystal storage device via the pipe 231.

Liquid crystal injection nozzle 240 and each liquid crystal injection nozzle 24
Liquid crystal flow path 242 as a liquid crystal storage unit for supplying liquid crystal to
Is provided. The liquid crystal injection nozzle 240 includes a sponge 241 as a liquid crystal holding member and a capillary tube 243 as a conduit connecting the sponge 241 and the liquid crystal flow path 242.
have. The sponge 241 is infiltrated with the liquid crystal sucked up from the liquid crystal channel 242 by the capillary phenomenon. The shape of the sponge 241 is, for example, a cylindrical shape, and the diameter of the sponge 241 is 1 to 2 times as large as the gap between the pair of first sealing materials 15 that will be the liquid crystal inlet 10. In this embodiment, the distance between the pair of first sealing members 15 is about 2 mm, and the diameter of the sponge 241 is about 3 mm.
~ 3.5 mm. In this way, the sponge 241
When the liquid crystal injection port 10 and the exposed substrate end are brought into contact with each other, the width of the liquid crystal injection port (the gap between the pair of first sealing materials 15) and the width of the sponge 241 are the same or the sponge is more By providing a slightly large size, it is possible to reduce the infiltration of the liquid crystal to the outside of the area surrounded by the open-curved sealing material 12 and the first sealing material 15. That is, when the width of the sponge 241 is made smaller than the width of the liquid crystal injection port 10, mixing of air bubbles into the area surrounded by the open-curved sealing material 12 and the first sealing material becomes a problem. On the other hand, when the width of the sponge 241 is larger than twice the width of the liquid crystal injection port 10, the liquid crystal that has penetrated outside the region surrounded by the open-curve seal material 12 and the first seal material 15 is laterally (Fig. 13 above, in the x direction). Considering the alignment error between the liquid crystal injection port 10 and the sponge 241, it is desirable to set the width of the sponge 241 larger than the width of the liquid crystal injection port 10.

Next, a liquid crystal injection method using the above-mentioned liquid crystal injection device 200 will be described with reference to FIGS. 6, 7, 13 and 15. FIG. 15 is a partially enlarged view of the strip panel P.

First, the moving mechanism 203 is operated to open the shutter 204 of the liquid crystal injection device 200, and the panel holding portion 2 is opened.
20 is moved to the outside of the vacuum chamber 201. Next, the strip panel P in an empty cell state is placed in the panel holding unit 220, the panel holding unit 220 is again carried into the vacuum chamber 201, and the shutter 204 is closed. Panel holder 220
Is lowered, the support pin 222 is inserted into the hole 221, and is supported by the support portion 206. At this time, the liquid crystal supply unit 21
0 is in a lowered state, and the liquid crystal injection port 10 is not in contact with the liquid crystal injection nozzle. Next, the pump 208 is operated to evacuate the inside of the vacuum chamber 201 to sufficiently evacuate the cells of the strip panel P, and depressurize the inside of the vacuum chamber including the cells.

Next, the operation of the pump 208 is stopped, the liquid crystal supply unit 210 is raised by the moving mechanism 202, and the liquid crystal injection port 10 and the sponge 241 of the liquid crystal injection nozzle 240 are brought into contact with each other. After that, air is introduced into the vacuum chamber 201 by a mechanism (not shown) to return the inside of the vacuum chamber 201 to the atmospheric pressure state. As a result, the liquid crystal infiltrated into the sponge 241 is injected into the cells of the strip panel P through the liquid crystal injection port 10 due to the pressure difference between the inside and the outside of the strip panel.

At the time of this liquid crystal injection step, in this embodiment, as shown in FIGS. 6, 13 and 15, the second sealing material 16 is provided, so that the liquid crystal injection port 10
On both sides of each, one first region 301 that is open only on the first side 2'c (4'c) side and two second regions 302 are provided.
It is in a state of being provided. As described above, the first area 301 and the second area 302 have the first side 2'c.
Since it is open only on the (4'c) side and the others are closed,
Even if the liquid crystal enters between the two substrates 2 and 4 other than the inlet 10, the liquid crystal first enters the first area 301 and is blocked, and the liquid crystal moves to the outside of the first area 301. There is no. Therefore, the liquid crystal is prevented from spreading in the direction along the first side 2'c (4'c). Further, for example, the liquid crystal passes through the end face of the substrate, and the first region 3 when viewed from the liquid crystal injection port 10.
Even if the liquid crystal enters between the two substrates 2 ′ and 4 ′ beyond 01, the liquid crystal enters the second region 302 and is blocked.
The liquid crystal does not move to the outside of this area. As described above, in the present embodiment, a plurality of regions for blocking the liquid crystal, which are opened only on the first side 2′c (4′c) side and closed on the other side, are provided instead of one. Therefore, it is possible to reliably prevent the spread of the liquid crystal infiltration between the two substrates. Further, when the liquid crystal injection nozzle 240 is used as in the present embodiment, the first side 2′c for blocking the liquid crystal is considered in consideration of misalignment between the liquid crystal injection port 10 and the liquid crystal injection nozzle 240. If only one region that is open only on the (4′c) side and that is closed on the other side is provided, it is not possible to sufficiently prevent the liquid crystal from penetrating when the misalignment occurs. By providing a plurality of such liquid crystal elements, it is possible to reliably prevent the spread of liquid crystal intrusion. In addition, in the present embodiment, the first area 301 is larger than the second area 302 in the sponge 241.
Since the distance between and is short, the width of the first region where liquid crystal is more likely to enter is narrower than that of the second region 302. In this way, by narrowing the width of the region where the liquid crystal is more likely to enter, the spread in the direction of the first side 2'c (4'c) when the liquid crystal enters between the two substrates 2'and 4 ' Can be made smaller. As described above, in the present embodiment, the second
By providing a plurality of sealing materials on both sides of the liquid crystal inlet 10, the infiltration of the liquid crystal between the two substrates can be reduced, so that the amount of liquid crystal used can be reduced and the liquid crystal can be used. Efficiency is improved.

Further, in this embodiment, FIG. 6 and FIG.
As shown in FIG. 3 and FIG. 15, since the third seal material 14 is provided, the space between the adjacent dummy seal material 13 and the open curved seal material 12 and the adjacent open curved seal material are provided. Liquid crystal is prevented from entering the gap. In the present embodiment, since the liquid crystal injection nozzle is locally arranged in accordance with the liquid crystal injection port 10, the space between the adjacent dummy seal material 13 and the open curved seal material 12 and the adjacent open curve. Although there is little possibility of liquid crystal infiltrating between the sealing materials 12 in a rectangular shape, the liquid crystal may infiltrate between the two substrates by striking the end faces of the substrates, thus blocking the infiltration of liquid crystal in this way. It is effective to provide the third sealing material 14. Therefore, the infiltration of the liquid crystal between the two substrates can be reduced, so that the amount of the liquid crystal used can be reduced and the liquid crystal utilization efficiency is improved.

Further, in this embodiment, FIG. 6 and FIG.
As shown in FIG. 3 and FIG. 15, since the fourth seal material 17 connected to the dummy seal material 13 and extending to the first side 2′c (4′c) is provided, liquid crystal is temporarily provided in this area. Even if the liquid crystal enters, the liquid crystal is blocked in the fifth region 305, does not spread to other regions, the amount of liquid crystal used can be reduced, and the liquid crystal utilization efficiency is improved.

Similarly, as shown in FIGS. 6, 13 and 15, the dummy seal member 13 is connected to the second side 2 '.
Since the fifth sealing material 18 extending to d (4′d) is provided, even if liquid crystal enters this area, the liquid crystal is blocked in the sixth area 306 and spreads to other areas. In this way, the amount of liquid crystal used can be reduced, and the liquid crystal utilization efficiency is improved.

As described above, 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 from the liquid crystal injection device 200.

After that, the liquid crystal injection port 10 is sealed with a sealing material and the liquid crystal that has infiltrated between the two substrates is removed by washing. In the present embodiment, the first side of the strip panel P'is Only cleaning is required, and the cleaning process can be simplified.
