BACKGROUND OF THE INVENTION
The present invention relates to a liquid crystal sealing frame and a liquid crystal sealing in a liquid crystal device that simultaneously manufactures a plurality of liquid crystal panels.
[0002]
[Prior art]
A liquid crystal device with a liquid crystal sandwiched between two electrode substrates has a simple structure, so it requires a small and thin TV, personal computer, watch, camera display device, touch panel input device, and printer. It is used in a wide range of fields such as optical shutter devices. In manufacturing this liquid crystal panel, it is common to arrange a large number of panels having the same shape on a large substrate in the previous process and produce a large number of panels at the same time. In particular, small panels are widely used because a large number of products can be produced at the same time, resulting in a significant reduction in manufacturing cost.
[0003]
A large number of liquid crystal devices include two large substrates on which a plurality of liquid crystal driving electrodes corresponding to each panel are arranged, and a plurality of sealing frames that are sandwiched between the large substrates and enclose liquid crystals corresponding to each panel. It is composed with. FIG. 9 is a perspective plan view of a liquid crystal device to be taken in large numbers, showing a conventional embodiment relating to the present invention, FIG. 10 is a partially enlarged view of FIG. 9, and FIG. 1 is a large upper substrate, 2 is a large lower substrate, a1, a2, a3, b1, b2,... C1 are separated along scribe lines 31 to 35 and 51 to 55 shown by two-dot chain lines. It is a panel. Inside the large substrates 1 and 2, a signal electrode group 15, a scan electrode group 14, and a connection terminal group 18 connected to the electrode group are wired to a terminal area 17 of the large lower substrate, respectively. Are opposed to each other with a sealing frame therebetween. The sealing frame 11 has the same shape as each panel, and the sealing frames corresponding to the panels a1, a2, a3... B1... C1 have 11a1, 11a2,. -11c1 ... Since the configuration of each panel is the same, the names and symbols of each part in the panel will be described with reference to FIG. 10 which is an enlarged view of the panels a1 and b1. Hereinafter, the panel code is treated as a suffix when it is necessary to explain the members unique to the panel.
The opening of the sealing frame 11 is a liquid crystal inlet formed by introducing projections 12 and 13. An area 17 surrounded by the scribe lines 41 that cut only the scribe lines 32, 51, 52 and the large upper substrate 1 is a terminal area, and 18 (m, n,..., W, x) connection terminal groups indicated by solid lines. Is arranged. A dotted line group 14 connected to m, n, o and v, w, x of the terminal 18 is a signal electrode group, which is wired to the large upper substrate 1 and is electrically connected by conductive particles mixed in the sealing frame. ing. A dotted line group 15 connected to p to u of the terminal group 18 is wired to the large lower substrate 2 with a scanning electrode.
[0004]
In the process of completing each panel as a liquid crystal panel from a large substrate, liquid crystal is injected and sealed by batch processing. This process is performed by making a large substrate into a strip shape. In order to make a strip shape, a scribe line along the liquid crystal inlet is cut. In other words, strips of a (a1 to a4), b (b1 to b4, the same applies below), c, and d are formed by cutting along the scribe lines 31 to 35. When this strip is placed in a vacuum environment, the projections 12 and 13 of the injection port are brought into contact with the liquid crystal immersion material by an injection method such as a liquid crystal or mat method, and then returned to atmospheric pressure to become a vacuum. Liquid crystal is sucked into the sealing frame, and the liquid crystal is filled. After the liquid crystal is injected, the liquid crystal injection port is sealed with a sealing material, and the liquid crystal is completely accommodated in the sealing frame. After that, the strip is cut along the scribe lines 41 to 42 and divided into individual panels.
Thus, many panels can be manufactured simultaneously by forming many panels on a large substrate.
[0005]
The sealing frame is formed by patterning a sealing material on one of the large substrates by printing and pressing the other large substrate. Since the sealing material is a thermosetting soft material such as an epoxy resin, a thick space is formed in the sealing frame before press contact, and the thickness is crushed to a predetermined thickness. For this reason, when the sealing frame is in a closed shape, there is no escape space for the air in the frame, and there is a risk of puncture due to the internal pressure. Since the liquid crystal inlet is open, it plays the role of air escape at the time of pressure contact, and the sealing frame shape is opened as a liquid crystal inlet of its own panel when it is sandwiched between large substrates before scribing In addition to having to be, it is not allowed to contact the sealing frame of the surrounding panel to become a dead end. That is, the area around the inlet must be open.
The projections 12 and 13 are formed from the sealing frame shape toward the outer periphery of the panel so that the liquid crystal can be reliably injected from the injection port when the liquid crystal is injected in a strip state. At the time of cutting to make a strip from a large substrate, a part of the protrusion is cut off, and the tips of the protrusions 12 and 13 have a shape exceeding the scribe line so that the cross section of the protrusion is flush with the cross section of the substrate. This is because if the cross section of the substrate and the cross section of the protrusion do not match, it is difficult to reliably suck in the liquid crystal due to the step. Further, even when the injection port is sealed after the liquid crystal is injected, if there is a step between the scribe cross section and the fill port cross section, liquid crystal residues are likely to accumulate in the gap, and the sealing material prevents the injection port from being reliably blocked. From this surface as well, it is necessary to simultaneously cut the protrusions.
[0006]
Reference numeral 20 denotes a filler that prevents the sealing material from flowing into the liquid crystal of the panel when sealing after the liquid crystal is injected. In order to inject liquid crystal, the larger inlet is easier, but the sealing after the injection becomes difficult accordingly. UV curable cream-like material is often used for the sealing material, and if the injection port is wide, the sealing material tends to flow into the injected liquid crystal, and the flowed part cannot exhibit the original liquid crystal performance. I want to keep the inflow of sealing material to a minimum. Therefore, when the injection port is made large, a dope 20 is provided in the injection portion to make the effective injection port small so as to stop the flow of the sealing material and prevent the sealing material from flowing into the panel. Yes.
Further, when the sealing material hardens, it hardens while shrinking. Since the inlet is vacant at the cut of the sealing frame, the shrinkage force tends to cause distortion of the substrate. The dote serves as a pillar of the space of the inlet, and also prevents the panel from being distorted by this contraction force.
[0007]
[Problems to be solved by the invention]
Since the dote which prevents inflow of a sealing material is arrange | positioned in a narrow place, a big area cannot be taken. In general, the pattern is printed and patterned together with the sealing frame. As apparent from FIG. 10, the dote 20 is very small compared to the continuous sealing frame 11. In the printing process, it is generally difficult to obtain small accuracy, and the sealing material is no exception. For this reason, the accuracy of the shape and position of the dowel is poor with respect to the accuracy of the sealing frame, and it has been necessary to design for the error. Various shape shapes have been proposed, but complicated shapes are larger and require more space, so there is another drawback that the electrode part that controls display is restricted.
As described above, it has been a problem to enable high-precision printing while ensuring the dope shape.
[0008]
In sealing the liquid crystal after the liquid crystal is injected, it is necessary to securely seal the injection port. In order to facilitate the cutting of the substrate, the scribe line is set not to cover the sealing frame. Therefore, in the liquid crystal device cut into a strip shape, there is a gap between the upper and lower substrates on the outer periphery of the sealing frame except for the cut surface of the projection which is the inlet. The liquid crystal remains in the gap after the liquid crystal filling operation. When sealing the liquid crystal injection port, it is desired to remove liquid crystal that does not have good affinity with the sealing material from the sealing portion. However, the gap between the upper and lower substrates is as narrow as about 4 to 10 microns, and the liquid crystal that has entered between the upper and lower substrates of the panel is difficult to remove, which is difficult with normal cleaning. Since the upper and lower substrate cross sections and the protrusion cross section are easy to clean, the surface and the sealing material are sealed together to seal. For this reason, it has been desired that the protrusion cross-sectional area be large. On the other hand, since unnecessarily widening the width of the protrusions makes the scribing operation difficult to that extent, there has been a demand for reducing the width as much as possible. One of the challenges was to deal with these conflicting requests in a well-balanced manner.
[0009]
  In order to cut the inlet projection at the cross section of the substrate, the projection must exceed the scribe line, and the projection of the liquid crystal injection part must be made when the sealing frame is installed. At the same time as the long, the protrusion around the tip of the injection port is a release partMakeI have to keep it. Therefore, an area margin around the inlet is necessary. Referring to FIG. 10, since the projections 12b1 and 13b1 of the panel b1 must exceed the scribe line 32, the front end portion remains on the adjacent panel a1 after the cutting. A part of the protrusion of the adjacent panel c1 is cut off from the panel b1, and the tip part is12c1 and 13c1And is left behind in the panel b1. Similarly, the front end of the panel b1 is left as a part of the panel a1. Since the remaining tip must be separated from the terminal group 18, the area of the terminal area 17 must be larger than that of the terminal group alone. For that reason, the panel of the same size has a drawback that the effective area of the liquid crystal becomes small. Further, the sealing frame of the panel of FIG. 9 contains conductive particles, and part of the protrusions remains in the terminal area because it contacts the external terminal group that is electrically connected to the terminal group 18, It was a cause of peeling and calling for electrical failure. To avoid this, rotate the panel pattern to match the inlet.MasterHas been proposed. FIG. 12 shows an example in which the pattern of the panel a1 is rotated 180 degrees so that the inlets face each other, and the vicinity of the scribe line 32 is shown. Reference numeral 61 denotes a center line of the panel. It is desirable that the injection port be as central as possible so that the liquid crystal can be injected into the sealing frame on average when the liquid crystal is injected, and in order to make the upper and lower panels the same panel, the two panels facing each other are The electrodes and the sealing frame are patterned so as to be point symmetric with respect to the intersection of the center line 61 and the scribe-in 32. On the other hand, in order to ensure the escape of air in the gap between the upper and lower substrates when forming the sealing frame, the periphery of the inlet must be opened, and as a result, as shown in the figure, the tip of the protrusion is cut simultaneously by one scribe line It was impossible to do. As described above, while cutting the projections forming the injection port, it has been a problem to increase the printing accuracy of the dowel and to ensure liquid crystal sealing.
[0010]
In order to solve the above-described problems, the present invention positions the liquid crystal injection port in the relatively center of the sealing frame, and one of the projections forming the injection port is nested in the injection port of the paired panel. With this shape, it is possible to cut all the projections at the same time when cutting both panels, and the tip of the cut nested projection becomes a dowel of the panel with the tip remaining and sealed. It is an object of the present invention to provide a liquid crystal device that restricts the inflow of a stopper and secures a sealing material to a panel more securely and does not hinder liquid crystal injection.
[0011]

The multi-piece substrate is characterized in that a bank is arranged inside the injection port of the other sealing frame adjacent to the one projection by having a configuration arranged so as to enter.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 are perspective plan views of the liquid crystal device according to the first embodiment of the present invention shown in FIG. 3, FIG. 1 is a partially enlarged view including a portion E in FIG. 3, and FIG. It is -B sectional drawing. 10 is the same as FIG. 10 described in the prior art, 1 is a large upper substrate, 2 is a large lower substrate, a1, a2, a3, b1, b2,... C1. It is a panel cut | disconnected along scribe lines 31-35 and 51-55. A signal electrode group, a scanning electrode group, and a connection terminal group connected to the electrode group are wired inside the large substrates 1 and 2, and a terminal area 17 of the large lower substrate 1 is provided.(17a1, 17b1, 17c1)The connection terminal groups are arranged respectively. The large substrates 1 and 2 are opposed to each other with a plurality of sealing frames represented by 11. In the present invention, an ellipse E is interposed as in a1-b1 and a2-b2 in FIG.ShiTwo panels are constructed in pairs. An ellipse E is the main part of the present invention, and FIG. 1 is an enlarged view of a pair of panels a1-b1 including this part. The liquid crystal injection port is a protrusion 24.(24a1, 24b1), 25(25a1, 25b1)One of the protrusions (the protrusion 25a1 of the panel a1 and the protrusion 25b1 of the panel b1) is nested in the other inlet. The four protrusions 24a1, 25a1, 24b1, and 25b1 to be paired are formed so as to straddle the scribe line 32 that divides the two panels. In FIG. 1, the protrusion 25b1 that is nested in the other inlet is formed in a substantially straight line substantially parallel to the protrusion 24a1 of the other inlet, and this is preferable, but it does not necessarily have to be a straight line. .
[0018]
  By forming the protrusions in this way, a panel having a pair of a, b, c, and d stripped from the large substrate along the scribe lines 31 to 35 is formed with the inlets facing each other. A separated protrusion remains in the liquid crystal injection port. FIG. 4 shows the panel b1 after cutting. Between the projections 24b1 and 25b1 forming the inlet of the panel b1, the panel a1 is cut before cutting.SealingThe tip 25'a1 of the protrusion 25a1 that has been integrated with the frame 11a1 is cut off and positioned. The separated distal end portion 25'a1 serves as the stub described with reference to FIG. 10, and serves to prevent the inflow of the liquid crystal sealing material and as a support for the injection port.
[0019]
Since the protrusions that are cut off and formed as such are formed as a continuous body of the sealing frame 11 before cutting, in the formation of the sticks that are often subjected to printing patterning, the protrusions are handled as compared to making the sticks alone. Easy and accurate shape can be easily realized.
[0020]
  FIG. 5 is a partial top view of FIG. 4 showing a cut surface of the panel b1 near the inlet. In addition to the liquid crystal inlets 24b1 and 25b1, the cut surface has a section of the projection tip 25'a1 of the panel a1 which functions as a dowel and the other projection of the other side of the panel a1 and the cross section of the substrate. Appear in the same plane. Since the conventional dote was in the injection port and was not nested, the projection cross section had only the two liquid crystal injection ports 24b1 and 25b1. According to the present invention, the cross-sectional area can be easily secured as shown in FIG.Used to seal or seal the inletThe affinity with the sealing material is increased, the fixing of the sealing material is stabilized, and more reliable sealing is possible. As described above, according to the present invention, it is possible to firmly fix the sealing material instead of simply expanding the protrusion.
[0021]
  In the present invention, since the injection port is nested, if the nesting position is set at an arbitrary position, the shape of the sealing frame becomes asymmetrical. In this case, two types of panels having different inlet positions can be formed in one large substrate. In other words, when the nesting position in FIG.a1The nesting position of the panel a1 viewed from the left side is shifted to the left. In this case, two types of jigs must be prepared when performing liquid crystal injection and sealing work in the step after cutting, which causes inconvenience. In addition, the liquid crystal injection port is provided on the panel for average liquid crystal injection into the sealing frame.LeIt is desirable to be in the center. This problem can be dealt with by specifying the position of the protrusion that becomes a defect. The explanation will be given with reference to FIG. In FIG. 4, t1 is the sealing frame width.Panel center line61 is the center line. t2 is the width of the injection port and is defined at the center of the projection serving as the injection port.Center line of protrusion62 is a protrusion that becomes a defect after cutting2The center of 5'a1. At this time, the projection center 62 is offset from the sealing frame center 61 by a quarter of the inlet width t2. In FIG. 4, the protrusion is a defect.2Since 5'a1 is offset to the right from the center of the panel, the protrusion of the panel b1 to be the stencil of the panel a12If the center of 5b1 is offset from the panel center 61 to the left side of the quarter of the inlet width, it can be easily confirmed that the shapes of the panels b1 and a1 are exactly the same. In actual work, the panel outlines, that is, the scribe lines 51 and 52 are used as work standards, so that the nesting protrusion is positioned at a position offset from the center 61 of the panel width which is substantially the same by a quarter of the inlet width. If it does, the said effect will be acquired. If the strip a cut with the liquid crystal injection port positioned in this way is rotated 180 degrees, it will have exactly the same shape as the strip b, so that the subsequent steps can be handled in the same way, and the shape of the completed panel is also completely It becomes the same thing and the process after a cutting | disconnection can be performed completely the same. Further, since the offset from the center is small, the liquid crystal can be injected on the average with almost no influence of the deviation from the center when the liquid crystal is injected.
[0022]
Various shapes have been proposed to prevent the sealing material from flowing into the liquid crystal part. For example, when the same shape as the dote 20 of FIG. 10 shown in the prior art is desired, the tip of the nesting corner may be made the same ellipse as the dote 20, and the shape is more accurate than single shape printing. Easy to print.
FIG. 6 shows another embodiment having a different shape, corresponding to the E portion of FIG. In this embodiment, 26a1 and 27a1 are the projections of the panel a1, 26b1 and 27b1 are the projections of the panel b1, and the shape of the tip 26 of the projection is T-shaped.
In FIG. 6, a projection 26b1 having a projection protruding from the vicinity of the tip is formed by forming the projection to be nested in the other inlet into a substantially straight line substantially parallel to the projection of the other inlet. Is prevented from entering.
In this way, any shape can be treated as a tip shape continuous with the protrusion, and the present invention can correspond to any shape.
[0023]
  7 and 8 show another embodiment relating to the present invention, in which the liquid crystal injection port is located laterally with respect to the terminal portion. 7 is a perspective plan view of the liquid crystal device, and FIG. 8 is a diagram.7It is the elements on larger scale of the F part periphery. In the present embodiment, since the projections forming the liquid crystal injection port are located laterally with respect to the terminal portion 17, the paired panels are a1 and a2. The reference numerals are in accordance with the conventional embodiment. 27a1,28a1 is the protrusion of panel a1, 27a2, 28a2 is a protrusion of the panel a2, and each protrusion is formed so as to straddle the scribe line 52. Since the liquid crystal injection and the injection port sealing are batch-processed in a strip shape, the scribe lines 51 to 55 are first performed in the cutting process to make the strip. That is, the strips are configured in the connecting direction of a1-b1-c1-d1 (hereinafter a2-b2-c2-d2, a3-b3...). In this embodiment, the inlets of the paired panels are opposite on the left and right sides with respect to the terminal portion 17, and the complete identity of the panel is lost, but each protrusion is formed so as to straddle the scribe line. After cutting along the line 52, each of the nested protrusions becomes the other stick, preventing the inflow of the sealing material and serving as a strong support, while the cutting surface contributes to the sealing reliability. It does not change to do.
[0024]
  There are two options for setting the position of the nested inlet in this case. One is a case where importance is attached to averaging at the time of liquid crystal injection, and the center line 63 serving as a reference adopts the center of the sealing frame width t4. The other is a case where work is emphasized based on the panel outer shape, and the center line 63 serving as a reference adopts the center of the panel width t5. In any case, the offset amount t6 of the center line 64 of the projection nested from the center line 63 is a quarter of the inlet width t3. Accordingly, in the former, the liquid crystal injection port is located at the same position with respect to the center of the sealing frame, so that the liquid crystal injection is made identical. In the latter, after the strip is cut, one strip (a2 -B2-c2-d2) is turned 180 degrees upside down, the injection port for the panel outline will be located at the same location as the other strip (a1-b1-c1-d1), so liquid crystal injection and sealing It is easy to share work jigs. Which one should be adopted may be decided according to the strength of the request.
    As described above, in the present invention, a plurality of single liquid crystal panels are formed on a large substrate, and then a large number of large substrates for taking out a single liquid crystal panel are arranged opposite to each other with a gap therebetween. In a liquid crystal device in which a sealing frame for injecting and sealing is provided and the sealing frame has a liquid crystal injection port formed of at least two protrusions, the liquid crystal injection ports of the sealing frame are opposed to each other. A pair panel is formed, and one of the two protrusions forming the inlet is nested in the other liquid crystal inlet of the pair panel and is disposed so as to straddle a cutting line that divides the pair panel. In addition, a plurality of single liquid crystal panels are formed on a large substrate and a large number of large substrates for taking out a single liquid crystal panel are taken out and a large number of large substrates are arranged opposite each other with a gap between them. For injecting and sealing In the liquid crystal device having a liquid crystal injection port formed of at least two protrusions in the sealing frame, the liquid crystal injection port of the sealing frame includes two paired panels that face each other and form a pair. A liquid crystal device having a configuration in which one of the two protrusions forming the injection port is disposed so as to straddle a cutting line that divides the pair panel at the same time as being nested in the other liquid crystal injection port of the pair panel is there.
Furthermore, these liquid crystal devices have a structure in which the nesting protrusion is longer than the other protrusion that continues to the same sealing frame.
Further, these liquid crystal devices have a configuration in which the nesting protrusion of the other inlet is formed in a substantially straight line substantially parallel to the protrusion of the other inlet.
Further, in these liquid crystal devices, the projections that are nested in the other injection port are formed substantially in a straight line substantially parallel to the projections of the other injection port, and have projections that protrude from the vicinity of the tip. Thus, the structure prevents the entry of impurities.
Further, these liquid crystal devices have a configuration in which the center of the nesting protrusion is located at a position offset by a quarter of the liquid crystal inlet width from the center of the sealing frame or the center of the panel outer shape taking the center in the same direction. Have.
[0025]
【The invention's effect】
  As described above, according to the present invention, when manufacturing a liquid crystal device that takes a large number, a pair of injection holes of two panels face each other and the projections forming the liquid crystal injection holes are nested. By forming so as to straddle the scribe line that separates the two, a part of the protrusion separated after the separation and cutting can play a role of preventing the inflow of the sealing material and serving as a strength support. In addition, the cutting of the protrusion and the cutting of the substrate are performed simultaneously by scribing.RuAs a result, the cross section is also formed in the same cross section, so that the affinity with the sealing material is increased and a firm sealing is possible.
[0026]
Furthermore, since the protrusions serving as the dowels are formed as a continuous body of the sealing frame, an arbitrary shape can be formed, and at the same time, a precise and precise shape can be easily realized.
[0027]
By offsetting the quarter of the inlet width from the center of the panel by nesting the position of the nesting protrusion, the shape of each panel in the liquid crystal device with a large substrate is made the same while nesting the protrusion forming the inlet. In addition, the inlet position relative to the panel outer shape can be made the same, and the manufacturing conditions can be made the same.
