  The present invention relates to a liquid crystal boat suitable for injecting liquid crystal into an empty liquid crystal display panel.

  2. Description of the Related Art Conventionally, a liquid crystal display device using a liquid crystal display panel as a display unit is known as a type of display device that displays information as various images such as characters and graphics. The liquid crystal display panel used in this liquid crystal display device forms an empty liquid crystal display panel (hereinafter referred to as an empty panel) provided with an inlet, and injects liquid crystal into the empty panel using a pressure difference. Yes.

  The liquid crystal injection device for injecting liquid crystal into the empty panel includes a liquid crystal boat having a liquid crystal reservoir for storing liquid crystal, and a capillary phenomenon that sucks the liquid crystal from the liquid crystal reservoir in which the lower part is immersed in the liquid crystal stored in the liquid crystal reservoir. One having a liquid crystal suction holding body twisted with a fiber material having a function of a product and a liquid crystal holding face material that holds the liquid crystal in a wet state has been proposed (for example, see Patent Document 1).

  3 and 4 show an example of a conventional liquid crystal injection apparatus. The conventional liquid crystal injection apparatus 101 has a disk-shaped liquid crystal boat 102 disposed inside the decompression tank V. FIG. On the upper surface of the liquid crystal boat 102, a liquid crystal reservoir 103 having an upper opening 103a having a substantially rectangular plane as a whole is recessed so that its longitudinal direction (vertical direction in FIG. 4) is the same as the longitudinal direction of the liquid crystal boat 102. Has been. The upper opening 103 a of the liquid crystal reservoir 103 is formed so that its longitudinal size is substantially equal to the longitudinal size of the liquid crystal suction holder Y placed on the liquid crystal reservoir 103. Further, the size in the width direction (left-right direction in FIG. 4) orthogonal to the longitudinal direction of the liquid crystal reservoir 103 is set in the width direction orthogonal to the longitudinal direction of the liquid crystal suction holder Y placed on the liquid crystal reservoir 103. It is formed about twice the size.

  The liquid crystal reservoir 103 is provided with a pair of left and right positioning guides 104 as positioning members for positioning the liquid crystal suction holder Y in the horizontal direction. These positioning guides 104 project from the bottom surface 103 b of the liquid crystal reservoir 103 along the longitudinal direction of the liquid crystal reservoir 103, and the upper surface thereof is flush with the upper surface of the liquid crystal boat 102. The distance between the positioning guides 104 is substantially equal to the size of the liquid crystal suction holder Y in the width direction, so that the liquid crystal suction holder Y is positioned between the positioning guides 104. It has become.

  That is, a space between the positioning guides 104 of the liquid crystal reservoir 103 is a holding body mounting area 105 on which the liquid crystal suction holding body Y is mounted. The region 105 is formed approximately equal to the size in the width direction.

  As shown in FIG. 4, the positioning guides 104 are divided along the longitudinal direction thereof, so that the liquid crystals L positioned on both sides of the positioning guides 104 can freely flow with each other. Yes. In addition, the distance between the inner side surface 103c located at both ends of the liquid crystal reservoir 103 in the width direction and the side surface of the positioning guide 104 facing each of the inner side surfaces 103c, that is, the longitudinal direction of the liquid crystal suction holder Y of the liquid crystal reservoir 103 The size in the width direction of the upper opening 103a located on the outer side in the width direction orthogonal to the width direction is smaller than the size in the width direction of the liquid crystal suction holder Y, for example, about half of the size in the width direction of the liquid crystal suction holder Y. Is formed.

  The liquid crystal suction holder Y is for sucking up the liquid crystal L and holding it in a wet state, and is formed in a rope shape having a substantially circular cross section by a yarn twisted with a fiber material such as glass fiber. The lower part of the liquid crystal suction holder Y is immersed in the liquid crystal L stored in the liquid crystal reservoir 103, and the upper part is exposed above the upper surface of the liquid crystal boat 102.

  The injection of the liquid crystal L into the empty panel P using the liquid crystal injection device 101 having such a configuration will be described.

  First, the inside of the decompression tank V is decompressed until the degree of vacuum necessary for injecting the liquid crystal L is reached. Next, in a state where the decompression tank V is decompressed, a panel moving means (not shown) is driven to move the empty panel P downward as indicated by an imaginary line in FIG. Contact the top of the body Y. Next, by releasing the decompression state of the decompression tank V and returning the inside of the decompression tank V to the atmospheric pressure, the liquid crystal L stored in the liquid crystal reservoir 103 is brought into contact with the liquid crystal suction holding body using the capillary phenomenon and the pressure difference. Y is injected into the empty panel P through the inlet Pa and injected, and the injection of the liquid crystal L into the empty panel P is finished.

  Further, in the injection of the liquid crystal L into the empty panel P using the conventional liquid crystal injection device 101, the air existing between the fibers constituting the liquid crystal suction holding body Y, the liquid crystal suction holding body Y and the liquid crystal L A deaeration process is required to remove air such as air entrapped in the contact portion between the liquid crystal L and the liquid crystal reservoir 103, or dissolved gas contained in the liquid crystal L itself. . In this degassing step, prior to the injection of the liquid crystal L into the empty panel P, the liquid crystal suction holder Y is placed in the liquid crystal reservoir 103 of the liquid crystal boat 102 and a predetermined amount of liquid crystal L is stored in the liquid crystal reservoir 103. In this state, the inside of the decompression tank V is decompressed. The deaeration process is performed every time the liquid crystal L is injected into the empty panel P. Furthermore, since the liquid crystal L stored in the liquid crystal reservoir 103 of the liquid crystal boat 102 is consumed by the injection of the liquid crystal L into the empty panel P, a new liquid crystal L is added to the liquid crystal reservoir 103 of the liquid crystal boat 102 at every injection or Replenishment is performed at relatively short injection intervals.

Japanese Patent Laid-Open No. 2002-40450

  However, the conventional liquid crystal injection device 101 has a problem in that the wasteful consumption of the liquid crystal L is large.

  That is, when the liquid crystal L is injected into the empty panel P by the conventional liquid crystal injection device 101, bubbles of the liquid crystal L are generated due to the reduced pressure in the deaeration process, and some of the bubbles spill out from the liquid crystal reservoir 103. That is, there is a problem that the liquid crystal L spills outside the liquid crystal boat 102.

  Therefore, in the conventional liquid crystal injection apparatus 101, a tray C such as an oil pan is disposed below the liquid crystal boat 102 indicated by an imaginary line in FIG. 4, and the liquid crystal L spilled from the liquid crystal boat 102 is collected by this tray. It is configured to be able to. Since the liquid crystal L collected by the tray C cannot be reused, it is discarded and the liquid crystal L is wasted.

  The bubbles of the liquid crystal L are mainly due to foaming from the liquid crystal suction holder Y. That is, most of the problems are caused by the air present between the fibers constituting the liquid crystal suction holder Y and the air entrapped in the contact portion between the liquid crystal suction holder Y and the liquid crystal L. Other than that, only a very small amount is caused by air entrapped in the contact portion between the liquid crystal L and the liquid crystal reservoir 103 or dissolved gas contained in the liquid crystal L itself. Therefore, the bubbles of the liquid crystal L are generated such that the surface of the liquid crystal suction holder Y is foamed.

  In order to deal with such problems, in the conventional liquid layer injection apparatus 101, the deaeration process of the liquid crystal L is divided into a plurality of times, for example, twice. Then, in the first deaeration step, a liquid crystal suction holder Y immersed in a small amount of liquid crystal L is placed in the liquid crystal reservoir 103 while pouring a smaller amount of liquid crystal L than is necessary for injecting the liquid crystal L into the empty panel P. In order to prevent the generation and growth of bubbles from exceeding the defoaming speed, the operator moves the vacuum degree inside the decompression tank up and down while visually checking the generation of bubbles and the state of defoaming. The gas is deaerated by gradually increasing it by lowering or stepping down (step down). Next, after the decompression state of the decompression tank V is released and the interior of the decompression tank V is returned to atmospheric pressure, the liquid crystal L is added to the liquid crystal reservoir 103 in the second degassing step, whereby the liquid crystal L is added to the empty panel P. Is supplied to the liquid crystal reservoir 103, and then the inside of the decompression tank V is decompressed again, and the dissolved gas contained in the added liquid crystal L, the added liquid crystal L and the liquid crystal reservoir are supplied. The gas entrapped in the contact portion 103 is degassed.

  However, what divides the degassing step of the liquid crystal L has a problem that it requires a great deal of labor and time to degas the liquid crystal L, resulting in poor productivity.

  In view of this, a liquid crystal injection device has been proposed in which in the deaeration process, liquid crystal bubbles can be eliminated almost simultaneously with the generation of liquid crystal bubbles by applying vibrations by an ultrasonic vibrator to the liquid crystals.

  However, in the liquid crystal injection device capable of forcibly defoaming the liquid crystal bubbles, the labor and time required for the deaeration process can be reduced, but the structure of the device is complicated. .

  Therefore, there is a demand for a liquid crystal boat that can prevent liquid crystal bubbles from spilling out of the liquid crystal reservoir without dividing the deaeration process and without complicating the structure of the apparatus.

  The present invention has been made in view of this point, and an object of the present invention is to provide a liquid crystal boat capable of reducing wasteful consumption of liquid crystal.

In order to achieve the above-described object, the liquid crystal boat according to the first aspect of the present invention is characterized in that the liquid crystal boat has an upper opening, is disposed inside the decompression tank, and is injected into the liquid crystal display panel. together but is stored, in the liquid crystal boat crystal suction holding body by twisting fiber material is immersed in the liquid that is stored has a reservoir liquid crystal is placed, the liquid crystal suction held inside of the liquid crystal reservoir A positioning member for positioning the body in the horizontal direction is provided, and the upper portion positioned on both outer sides of the positioning member, with the width direction being a direction perpendicular to the longitudinal direction of the liquid crystal suction holding body of the liquid crystal reservoir The size of the opening in the width direction is at least twice the width of the liquid crystal suction holder .

It is preferable that the positioning member is divided and formed along the longitudinal direction so that liquid crystals located on both sides of the positioning member can freely flow .

  Further, of the inner surface of the liquid crystal reservoir, at least an inner surface located in the width direction orthogonal to the longitudinal direction of the liquid crystal suction holder is an inclined surface inclined toward the liquid crystal suction holder side. Is preferred.

  Furthermore, it is preferable that the edge located in the bottom face side of the said inclined surface is formed in the width direction outer side of the holding body mounting area | region in which the said liquid crystal suction holding body of the said liquid crystal reservoir is mounted.

The distance between the inner surface of the liquid crystal reservoir in the longitudinal direction of the liquid crystal suction holder and the end surface in the longitudinal direction of the liquid crystal suction holder is preferably at least twice the size in the width direction of the liquid crystal suction holder. .

According to the liquid crystal injection device of the present invention, it is possible to prevent liquid crystal bubbles from spilling to the outside due to the shape effect of the liquid crystal reservoir itself, so that the wasteful consumption of liquid crystal can be reduced. Excellent effect.

  The present invention will be described below with reference to embodiments shown in the drawings. In addition, the same code | symbol is attached | subjected in drawing about the structure same as the conventional thing mentioned above.

  1 and 2 show an embodiment of a liquid crystal boat according to the present invention. FIG. 1 is a cross-sectional view showing a main part configuration, and FIG. 2 is a reduced plan view of FIG.

  The liquid crystal boat 1 of the present embodiment is arranged in a decompression tank (V in FIG. 3) as in the conventional case, and is formed in a planar rectangular disk shape as shown in FIGS. ing. A liquid crystal reservoir 2 having a planar rectangular upper opening 2 a is recessed on the upper surface of the liquid crystal boat 1 so that its longitudinal direction (vertical direction in FIG. 2) is the same as the longitudinal direction of the liquid crystal boat 1. Yes. The upper opening 2a of the liquid crystal reservoir 2 is formed with a size LA in the longitudinal direction and a size WA in the width direction (left-right direction in FIG. 2) orthogonal to the longitudinal direction. The size of the upper opening 2a of the liquid crystal reservoir 2 will be described in detail later.

  Liquid crystal L is stored in the liquid crystal reservoir 2 and a liquid crystal suction holder Y is detachably mounted thereon. As shown in FIG. 1, the upper part of the liquid crystal suction holder Y is exposed above the upper surface of the liquid crystal boat 1, and the lower part of the liquid crystal suction holder Y is immersed in the liquid crystal L stored in the liquid crystal reservoir 2. It has become.

  The liquid crystal suction holder Y is for sucking the liquid crystal L stored in the liquid crystal reservoir 2 and holding it in a wet state, and is formed in a rope shape having a substantially circular cross section by a yarn twisted with a fiber material. . As the fiber material, glass fiber is generally used, and is excellent in wettability with the liquid crystal L as required for the specifications of the liquid crystal L, and does not adsorb an amine-based dopant component, fluororesin fiber, polyethylene (PE) Polyolefin fibers such as polypropylene (PP) and ethylene-propylene copolymer are also selectively used.

  The liquid crystal reservoir 2 according to the present embodiment is provided with a pair of left and right positioning guides 3 as positioning members for positioning the liquid crystal suction holder Y in the horizontal direction. These positioning guides 3 project from the bottom surface 2 b of the liquid crystal reservoir 2 along the longitudinal direction of the liquid crystal reservoir 2, that is, the longitudinal direction of the liquid crystal suction holder Y. Further, the interval Wa between the positioning guides 3 is formed substantially equal to the size (diameter) Ya in the width direction of the liquid crystal suction holder Y. Furthermore, as shown in FIG. 2, both positioning guides 3 are divided and formed along the longitudinal direction thereof, so that the liquid crystals L located on both sides of the positioning guide 3 can freely flow with each other. ing. Furthermore, the upper surfaces of both positioning guides 3 are formed flush with the upper surface of the liquid crystal boat 1.

  Therefore, in the liquid crystal boat 1 of the present embodiment, a portion sandwiched between the positioning guides 3 of the liquid crystal reservoir 2 is a holding body mounting region 4 for mounting the liquid crystal suction holding body Y. The liquid crystal suction holding body Y is placed in this holding body placing area 4 in a state of being positioned.

  The positioning guide 3 may be formed by a single flat plate. In this case, the liquid crystal L positioned on both sides of the positioning guide 3 can freely flow to each other by providing a groove at the lower end located on the bottom surface 2b side of the flat liquid crystal reservoir 2 or providing a plurality of through holes in the flat plate. It is important to make it happen.

  As the positioning guide 3, a plurality of liquid crystal suction holders Y can be positioned in the horizontal direction. For example, a plurality of positioning guides 3 are provided on both sides of the liquid crystal suction holder Y on the bottom surface 2b of the liquid crystal reservoir 2. It is good also as a structure which arranges a pin. Of course, the positioning guide 3 may be detachably attached to the bottom surface 2 b of the liquid crystal reservoir 2.

  Further, the positioning member can be changed according to the shape of the liquid crystal suction holder Y and the like. For example, when the cross-sectional shape of the liquid crystal suction holding body Y is a quadrangular shape whose upper surface is an arch, the positioning guide 3 is not provided, but a guide hole provided on the bottom surface of the liquid crystal suction holding body Y is provided on the bottom surface of the liquid crystal reservoir 2 It can be set as the structure etc. which are fitted to the positioning pin provided in 2b.

  Of the size WA in the width direction of the upper opening 2a of the liquid crystal reservoir 2, the size Wb in the width direction of the upper opening 2a located on the outer side in the width direction perpendicular to the longitudinal direction of the liquid crystal suction holder Y of the liquid crystal reservoir 2 is These are set to be at least twice the size Ya of the liquid crystal suction holder Y in the width direction. That is, the distance between the upper opening end of the inner side surface 2c located in the width direction of the inner surface of the liquid crystal reservoir 2 and the opposite side surface of the positioning guide 3 facing the upper opening end of the inner side surface 2c The suction holder Y is at least twice the size Ya in the width direction. If the size Wb in the width direction of the upper opening 2a is less than this range, bubbles of the liquid crystal L tend to spill out of the liquid crystal reservoir 2.

  If the positioning member is not configured to provide the positioning guide 3, but the guide hole provided on the bottom surface of the liquid crystal suction holder Y is fitted to the positioning pin provided on the bottom surface 2b of the liquid crystal reservoir 2, The size Wb in the width direction of the upper opening 2a located outside in the width direction orthogonal to the longitudinal direction of the liquid crystal suction holder Y of the liquid crystal reservoir 2 is the upper opening 2a directly adjacent to the side of the liquid crystal suction holder Y. The size in the width direction.

  The size LA in the longitudinal direction of the liquid crystal reservoir 2 is defined between the inner end surface 2d positioned in the longitudinal direction of the inner surface of the liquid crystal reservoir 2 and the end surface of the liquid crystal suction holding body Y facing the inner end surface 2d. Each of the sizes can be arranged with a predetermined interval La. That is, the size LA in the longitudinal direction of the upper opening 2a of the liquid crystal reservoir 2 is formed by adding the size in the longitudinal direction of the liquid crystal suction holder Y to twice the size of the interval La. The size of the interval La is more preferably at least twice the size Ya of the liquid crystal suction holder Y in the width direction.

  Therefore, the shape of the liquid crystal reservoir 2 itself that prevents the bubbles of the liquid crystal L generated by the decompression of the present embodiment from spilling outside from the liquid crystal reservoir 2 is at least the width direction orthogonal to the longitudinal direction of the liquid crystal suction holder Y The width W of the upper opening 2a located outside is set to be not less than twice the size Ya of the liquid crystal suction holder Y in the width direction.

  The inner side surface 2c is an inclined surface inclined upward at a predetermined angle toward the bottom surface 2b of the liquid crystal reservoir 2, that is, an inclined surface toward the liquid crystal suction holder Y side, and is located on the bottom surface side of the inclined surface. The end edge is disposed on the outer side in the width direction of the holding body mounting region 4 on which the liquid crystal suction holding body Y of the liquid crystal reservoir 2 is mounted, in the present embodiment, on the outer side of the positioning guide 3. The angle formed by the inclined surface which is the inner surface 2c and the bottom surface 2b of the liquid crystal reservoir 2 is 10 to 45 degrees, preferably 15 to 30 degrees, although it depends on the size of the liquid crystal suction holder Y. If the angle formed between the inclined surface of the inner surface 2c and the bottom surface 2b of the liquid crystal reservoir 2 is less than this range, the bubbles of the liquid crystal L generated at the time of decompression are prevented in the width direction so that the bubbles of the liquid crystal L do not spill from the liquid crystal reservoir 2. There is a tendency that it is not possible to obtain the effect of moving to the center. On the other hand, when the angle exceeds this range, the liquid crystal L for holding the liquid crystal suction holder Y in a wet state tends to increase. The inclination angle is not constant, and the inclination angle may be increased as it approaches the bottom surface 2b.

  Also, the inner end face 2d is more preferably inclined similar to the inner face 2c.

  In addition, when the liquid crystal boat 1 according to the present embodiment simultaneously injects the liquid crystal L into a plurality of empty panels (P in FIG. 3), the empty panel has an injection port (Pa in FIG. 3) having a linear shape. Arranging in the vertical direction is preferable in the sense that positioning of the injection port can be facilitated.

  Further, by arranging a plurality of liquid crystal boats 1 in the decompression tank V in parallel with each other, the liquid crystal L can be injected into more empty panels at the same time.

  Next, the operation of the present embodiment having the above-described configuration will be described.

  Injecting the liquid crystal L into the empty panel P using the liquid crystal boat 1 of the present embodiment places the liquid crystal boat 1 at a predetermined position inside the decompression tank, and thereafter, the liquid crystal is placed in the holding body placement region 4 of the liquid crystal reservoir 2. While the suction holding body Y is placed, the inside of the decompression tank is depressurized until the degree of vacuum necessary for injecting the liquid crystal L is reached in a state where a predetermined amount of the liquid crystal L is stored in the liquid crystal reservoir 2 of the liquid crystal boat. By this decompression, the gas is degassed from the liquid crystal L, and the liquid crystal suction holder Y is held in a wet state by the liquid crystal L not containing the gas.

  At this time, the bubbles of the liquid crystal L generated by the reduced pressure are held inside the liquid crystal reservoir 2 until the bubbles disappear due to the shape effect of the liquid crystal reservoir 2 even when the generation and growth of bubbles exceed the defoaming speed. Is done. As described above, since the bubbles of the liquid crystal L generated by the decompression are reliably held inside the liquid crystal reservoir 2 until the bubbles disappear due to the shape effect of the liquid crystal reservoir 2, the deaeration process is divided as in the prior art. There is no need.

  Next, in a state where the decompression tank V is decompressed, a panel moving means (not shown) is driven, the empty panel (P in FIG. 3) is moved downward, and the inlet (Pa in FIG. 3) is moved to the liquid crystal suction holder. Contact Y. Next, by releasing the decompression state of the decompression tank and returning the inside of the decompression tank to the atmospheric pressure, the liquid crystal L stored in the liquid crystal reservoir 2 using the capillary phenomenon and the pressure difference is removed from the liquid crystal suction holding body Y. The liquid is injected by being fed into the empty panel through the inlet, and the injection of the liquid crystal L into the empty panel is completed.

  As described above, according to the liquid crystal boat 1 of the present embodiment, bubbles of the liquid crystal L generated by decompression are prevented from spilling out from the liquid crystal reservoir 2 by the shape of the liquid crystal reservoir 2 itself, that is, the shape effect of the liquid crystal reservoir 2. can do.

  This was confirmed by the results of manufacturing experiments using a liquid crystal display panel for mobile phones.

  In the production experiment, the size Wb in the width direction of the upper opening 2a located outside the liquid crystal suction holder Y in the liquid crystal reservoir 2 is 3.6 times the size Ya in the width direction of the liquid crystal suction holder Y. A product in which the angle formed between the inclined surface of the inner side surface 2c and the bottom surface 2b is 15 degrees is a product of the present invention, and the size Wb of the upper opening 2a in the width direction outside the liquid crystal suction holding body Y of the liquid crystal reservoir 2 Is a half of the size Ya of the liquid crystal suction holding body Y in the width direction, the inner side surface 2c is not inclined and is a vertical wall with respect to the bottom surface 2b, and the conventional product is used. The conditions were the same.

  Then, when the liquid crystal L was injected into about 100,000 liquid crystal display panels for each of the present product and the conventional product, the wasteful consumption of the liquid crystal L in the present product per one liquid crystal display panel (the saucer) The amount of spillage of liquid crystal L from the liquid crystal boat 1 accumulated in C) is about 1/25 of the wasteful consumption of liquid crystal L in the conventional product (the product of the present invention is 0.0001 grams: the conventional product is 0.0025 grams) It was possible to obtain an experimental result that The results of this production experiment are shown in Table 1 below.

  In addition, it is estimated that the wasteful consumption of the liquid crystal L in the product of the present invention is not a bubble spill of the liquid crystal L, but a part of what is scattered and scattered when the bubbles disappear.

  Therefore, according to the liquid crystal boat 1 of the present embodiment, it is possible to reliably and easily reduce the wasteful consumption of the liquid crystal L. That is, the yield of expensive liquid crystal L can be improved.

  Further, according to the liquid crystal boat 1 of the present embodiment, since it is not necessary to divide the degassing step, the labor and time required for degassing can be reliably and easily reduced as compared with the case where the conventional degassing step is divided. can do. As a result, it is possible to save labor by automatically controlling the deaeration process, so that it is possible to easily improve productivity and save labor.

  Further, according to the liquid crystal boat 1 of the present embodiment, the liquid crystal bubbles are not eliminated almost simultaneously with the generation of the liquid crystal bubbles by applying vibration by the conventional ultrasonic vibrator to the liquid crystal, but the liquid crystal reservoir 2 itself Since the bubbles of the liquid crystal L can be prevented from spilling outside due to the shape effect, the structure of the apparatus is not complicated.

  Furthermore, according to the liquid crystal boat 1 of the present embodiment, the wasteful consumption of the liquid crystal L can be reduced, so that the replenishment amount of the liquid crystal L that is newly replenished to the liquid crystal reservoir 2 of the liquid crystal boat 1 is reduced as compared with the conventional case. be able to.

  Furthermore, according to the liquid crystal boat 1 of the present embodiment, since the volume of the liquid crystal reservoir 2 is larger than the conventional one, the number of times the liquid crystal L is poured into the liquid crystal reservoir 2 can be reduced.

  Therefore, according to the liquid crystal boat of the present embodiment, the productivity of the liquid crystal display panel and the labor saving can be easily achieved, and the cost of the liquid crystal display panel can be reduced.

  Further, according to the liquid crystal boat 1 of the present embodiment, the inner side surface 2c arranged in the width direction of the liquid crystal reservoir 2 is an inclined surface that is inclined toward the liquid crystal suction holder Y side, and therefore is generated by pressure reduction. Since the bubbles of the liquid crystal L can be brought closer to the center in the width direction of the upper opening 2a, that is, the outer peripheral surface of the liquid crystal suction holder Y, the effect of preventing the bubbles of the liquid crystal L from spilling to the outside is increased. be able to. This can hold the liquid level of the liquid crystal L stored in the liquid crystal reservoir 2 higher than when the inner side surface 2c is perpendicular to the bottom surface 2b. Even when the replenishment amount is less than the conventional amount, the lower portion of the liquid crystal suction holder Y can be reliably held below the liquid level of the liquid crystal L. That is, even if the size WB in the width direction of the upper opening 2a located on the side of the liquid crystal suction holder Y of the liquid crystal reservoir 2 is increased, the lower part of the liquid crystal suction holder Y can be easily immersed in the liquid crystal L. .

  Furthermore, according to the liquid crystal boat 1 of the present embodiment, the edge located on the bottom surface side of the inclined surface is in the width direction of the holder mounting region 4 on which the liquid crystal suction holder Y of the liquid crystal reservoir 2 is mounted. Since it is formed outside, the liquid level of the liquid crystal L stored in the liquid crystal reservoir 2 can be easily increased without interfering with the position where the liquid crystal suction holder Y is disposed.

  Furthermore, according to the liquid crystal boat 1 of the present embodiment, the positioning guide 3 as a positioning member for positioning the liquid crystal suction holding body Y in the horizontal direction is provided inside the liquid crystal reservoir 2. The body Y can be positioned reliably and easily.

  Further, according to the liquid crystal boat 1 of the present embodiment, the size Wb in the width direction of the upper opening 2a located outside the liquid crystal suction holding body Y of the liquid crystal reservoir 2 is formed larger than the conventional size. Secondly, it is possible to obtain a secondary effect that the liquid crystal L can be prevented from spilling when the liquid crystal L is replenished manually using an injection needle.

  The liquid crystal boat of the present invention can be used for injecting liquid crystal into a wide variety of liquid crystal display panels such as a liquid crystal television and a liquid crystal monitor, as well as a liquid crystal display panel used in a display unit of a mobile phone.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
