Abstract

PROBLEM TO BE SOLVED: To provide a liquid crystal display excellent in displaying quality and restrainable of loss sustained by manufacturing inferior goods to a minimum. SOLUTION: A regular seal 12 and an auxiliary seal 14 are applied to a transparent substrate 10 with a seal application device. The height of the auxiliary seal 14 is made higher than that of the regular seal 12. As a result, when an array substrate is assembled to the transparent substrate 10, a space sustaining material 11 dispersed on the transparent substrate 10 comes in contact with the array substrate and keeps the liquid crystal LC orientation from being disarrayed. Likewise, one of the auxiliary seal 14 is defined as a device ID seal 14b whose configuration is varied by the seal application device. As a result, an abnormity seal application device can immediately be specified by simply observing the device ID seal 14b even if there is abnormality in the seal process.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intermediate device for a liquid crystal display device, a liquid crystal display device using the same, and a method of manufacturing the same. More particularly, the present invention relates to an intermediate device between a transparent substrate and an array substrate. The present invention relates to an intermediate device for a liquid crystal display device provided with a seal, a liquid crystal display device using the same, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, even when a transparent substrate and an array substrate are assembled to produce a liquid crystal display device having a certain size, for example, 10.4 inches, this seal is generally used. It was applied, but the auxiliary seal was not applied. As can be seen from FIGS. 12 and 13, even when the auxiliary seal 14 is applied, the gap between the transparent substrate 10 and the array substrate 16 is kept constant, The auxiliary seal 14 was applied at the same height as the main seal 12 in order to reduce the resulting displacement between the transparent substrate 10 and the array substrate 16. The shape of the auxiliary seal 14 is a straight line,
Even when there are a plurality of seal applying devices for applying the auxiliary seal 14, all the seal applying devices apply the auxiliary seal 14 having the same shape.

[0003] On the other hand, the trend of narrowing the frame of the liquid crystal display device has been increasing year by year, and the height of application of the main seal 12 has also been reduced accordingly. However, the main seal 12
As the height of the coating becomes lower, as can be seen from FIG.
When assembling the substrates, the transparent substrate 10 and the array substrate 16
And the gap holding material 11 between these substrates may come into contact with the pixel openings of the array substrate 16 or the transparent substrate 14 to disturb the alignment of the liquid crystal. That is, after the transparent substrate 10 and the array substrate 16 are overlaid and the main seal 12 and the auxiliary seal 14 are cured, the gap holding material 11 sprayed on the transparent substrate 10 contacts the array substrate 16. Rubbing treatment, the transparent substrate 10 or the array substrate 1
Disturbance was generated on the inner surface of No. 6 and the orientation of the liquid crystal was likely to be disturbed. In other words, the gap holding material 11 may come into contact with the substrate on the opposite side to which the gap holding material 11 has been applied, thereby disturbing the orientation.

In the case where a plurality of seal applying devices are used, if the auxiliary seal 14 is not applied, or if the auxiliary seal 14 having the same shape is applied to all the seal applying devices, the seal is inspected in the sealing process. When an abnormality was found in the process, it was not known which seal applying device had an abnormality. For this reason, it was necessary to stop all the seal coating devices and all the lines, and then check which seal coating device had an abnormality.

[0005]

As described above, in the prior art, the gap holding material 11 between the transparent substrate 10 and the array substrate 16 comes into contact with the transparent substrate 10 or May be disturbed.

Further, when an abnormality is found in the sealing process in the inspection in the sealing process, it takes a long time for feedback. That is, it was not possible to identify which of the plurality of operating seal applicators has an abnormality by merely looking at the liquid crystal display device having an abnormality in the seal. For this reason, all of the lines of the seal application devices that are operating plural units have to be temporarily stopped to search for an abnormal seal application device.

[0007] The present invention has been made in view of the above problems, and even when the height of application of the present seal is reduced,
It is an object of the present invention to provide an intermediate device for a liquid crystal display device in which the alignment of liquid crystal is not disturbed, a liquid crystal display device using the same, and a method for manufacturing the same. That is, an object is to provide a liquid crystal display device having excellent display quality. It is still another object of the present invention to provide a method of manufacturing a liquid crystal display device that can provide quick feedback when there is an abnormality in a sealing process.
In other words, it is an object of the present invention to identify a seal applying device in which an abnormality has occurred simply by looking at an auxiliary seal of an intermediate liquid crystal display device (an intermediate device for a liquid crystal display device) in which the seal has an abnormality.

[0008]

In order to solve the above-mentioned problems, an intermediate device for a liquid crystal display device according to the present invention comprises an array substrate having a liquid crystal driving circuit for driving liquid crystal, and a transparent substrate facing the array substrate. A substrate, provided between the array substrate and the transparent substrate, for maintaining a constant gap between the array substrate and the transparent substrate, a gap holding material, and the gap between the array substrate and the transparent substrate Provided in between,
A main seal, which seals liquid crystal between the array substrate and the transparent substrate and seals the liquid crystal therebetween, is provided outside the main seal in a substrate to which the main seal is applied among the array substrate and the transparent substrate. , And an auxiliary seal formed higher than the main seal.

Also, an array substrate having a liquid crystal driving circuit for driving liquid crystal, a transparent substrate facing the array substrate, and a transparent substrate provided between the array substrate and the transparent substrate are provided. A main seal and an auxiliary seal provided outside the main seal, which are used to adhere the substrate and seal the liquid crystal therebetween, are provided, and the shape of the auxiliary seal is changed for each device that forms the auxiliary seal. , Which are different from each other.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) In the first embodiment, when assembling the transparent substrate and the array substrate, the height of the auxiliary seal is made higher than that of the main seal, and the gap holding material sprayed on the transparent substrate is in contact with the array substrate. The contact is prevented from disturbing the alignment of the liquid crystal. Further, by using one of the auxiliary seals as a device ID seal having a different shape for each seal coating device, when there is an abnormality in the sealing process, the abnormal seal application device can be quickly identified. It is like that.

A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a transparent substrate in a plan view,
FIG. 2 is a view showing a cross section of the intermediate device for a liquid crystal display device in a state where the transparent substrate and the array substrate are overlapped. FIG. FIG. 4 is a diagram showing a cross section in a state where the liquid crystal display device is completed.

As can be seen from FIG. 1, first, the transparent substrate 1
0 is formed. That is, the transparent substrate on which the electrodes opposed to the thin film transistors formed on the array substrate 16 described later are formed is washed. After this cleaning treatment, an alignment film is applied and a rubbing treatment is performed. This allows
A transparent substrate 10 is formed.

Next, the main seals 12 and 12 and the auxiliary seals 14 and 1 are applied to the transparent substrate 10 by a seal coating device.
4, 14, and 14 are applied simultaneously. As a seal applying device for applying the main seals 12, 12 and the auxiliary seals 14, 14, 14, 14, a dispenser method for extruding a seal material with a tube, a print method for transferring the seal material, and the like are used. is there. Subsequently, the gap holding material 11 is sprayed inside the main seals 12 and 12. The main seals 12 and 12 have an inlet 1 for injecting liquid crystal.
2a and 12a are formed. In addition, auxiliary seal 1
4, 14, 14, 14 are applied to empty areas outside the main seals 12, 12 on the transparent substrate 10. Of these auxiliary seals 14, 14, 14, 14, the upper left, lower left, and upper right auxiliary seals 14, 1
Reference numerals 4 and 14 constitute the normal auxiliary seals 14a, 14a and 14a having the same linear shape even when a plurality of seal applying devices are used. The auxiliary seal 14 at the lower right in the figure constitutes a device ID seal 14b having a refraction shape changed in shape for each seal coating device. As can be seen from FIG.
a, 14a, 14a, the height of the device ID seal 14b
It is formed so as to be higher than the main seals 12 and 12. For example, in the present embodiment, the normal auxiliary seal 14
a, 14a, 14a, the height of the device ID seal 14b
It is about 1.5 to 3.0 times the height of the main seals 12,12.

Next, as can be seen from FIG. 2, the array substrate 16 is overlaid on the transparent substrate 10. That is, the main seals 12, 12, the auxiliary seals 14, 14, 14, 14,
The array substrate 16 is superimposed on the transparent substrate 10 coated with. As a pre-process, a cleaning process is performed on the array substrate 16 after the thin film transistors are formed, an alignment film is applied, and a rubbing process is performed. This figure 2
As shown in FIG. 2, when the transparent substrate 10 and the array substrate 16 are simply overlapped, the main seal 12 and the gap holding material 11
Since the auxiliary seal 14 is higher than the auxiliary seal 14,
Are not in contact with the array substrate 16. Therefore, even when the transparent substrate 10 and the array substrate 16 are displaced from each other, the gap holding material 11 does not disturb the rubbed inner surfaces of the transparent substrate 10 and the array substrate 16.

Next, as can be seen from FIG. 3, the main seal 12 and the auxiliary seal 14 are cured while pressing the transparent substrate 10 and the array substrate 16 which are overlapped. As a result, the transparent substrate 10 and the array substrate 16 are
And the auxiliary seal 14. Subsequently, an inspection in the sealing process is performed to check whether the transparent substrate 10 and the array substrate 16 are properly sealed by the main seal 12 and the auxiliary seal 14.

Next, as can be seen from FIG. 4, after the inspection in the sealing step, unnecessary portions of the intermediate liquid crystal display device (intermediate device for liquid crystal display device) are cut off and cut to a desired panel size. That is, the intermediate liquid crystal display device (intermediate device for a liquid crystal display device) is divided into upper and lower parts, and both sides where the auxiliary seal 14 is applied are cut off. Next, liquid crystal LC is injected into this intermediate liquid crystal display device (intermediate device for liquid crystal display device). That is,
The liquid crystal LC is injected into the sealed space surrounded by the transparent substrate 10, the array substrate 16 and the main seal 12 from the above-described injection port 12a. Thereafter, the inlet 12a of the main seal 12 is sealed. Subsequently, polarizing plates 18 and 18 are attached to the front surfaces of the transparent substrate 10 and the array substrate 16, respectively. Further, this intermediate liquid crystal display device (intermediate device for liquid crystal display device)
A drive circuit is mounted on the periphery of the. Then, a backlight 20 is attached to the surface side of the polarizing plate 18 on the lower side in the figure. As described above, the main seal 12 and the auxiliary seal 14 are provided between the transparent substrate 10 and the array substrate 16 and the liquid crystal LC is sealed inside the main seal 12 to complete the liquid crystal display device.

As described above, according to the first embodiment of the present invention, the height of the auxiliary seal 14 is made higher than that of the main seal 12, so that when the transparent substrate 10 and the array substrate 16 are assembled, the transparent substrate The orientation of the substrate 10 and the array substrate 16 is not disturbed. That is, as can be seen from FIG. 2, when assembling the transparent substrate 10 and the array substrate 16, when the transparent substrate 10 and the array substrate 16 are overlapped, the gap holding material 11 does not contact the array substrate 16.
For this reason, even after the transparent substrate 10 and the array substrate 16 are displaced from each other before the main seal 12 and the auxiliary seal 14 are cured after the transparent substrate 10 and the array substrate 16 are The dispersed gap holding material 11 does not come into contact with the array substrate 16 and disturb the alignment of the liquid crystal LC. That is, even when the space between the transparent substrate 10 and the array substrate 16 becomes narrow, the gap holding material 11 comes into contact with the pixel openings of the array substrate 16 and the inside of the rubbed array substrate 16 is removed. It does not disturb the surface.
Further, the gap holding material 11 sprayed on the transparent substrate 10 comes into contact with the array substrate 16 on the opposite side, so that the gap holding member 11 is not displaced and disturbs the orientation of the transparent substrate 10. For this reason, a liquid crystal display device with very good display quality and excellent contrast can be manufactured.

Further, the device ID in the auxiliary seal 14
Since the shape of the seal 14b differs for each seal coating device,
When there is an abnormality in the sealing process, even if a plurality of seal applying devices are operating, the abnormal seal applying device can be identified quickly. That is, when an abnormality is found in the sealing process in the inspection in the sealing process, the device ID seal 14 of the intermediate device for the liquid crystal display device having the abnormality is detected.
By looking at the shape of the device ID seal 14b
Can be specified. That is, it is possible to immediately identify the seal applying device that has applied the main seal 12 having the abnormality. As a result, the line of the seal coating device having the abnormality can be stopped quickly. For this reason, it is possible to minimize the damage caused by the production of defective products.

FIGS. 5A to 5D show the auxiliary seal 14.
FIG. 9 is a view showing a modified example of the refraction shape of the device ID seal 14b in FIG. As shown in these figures, by changing the bending shape of the device ID seal 14b for each seal coating device, even if there is an abnormality in the sealing process, the abnormal seal application device is immediately identified. be able to. In the combination shown in FIG. 5, even when the four seal applying devices 1 to 4 are operated at the same time, the seal applying devices 1 to 4 It is immediately apparent which of the coating devices 4 is the seal coating device manufactured by the intermediate device for the liquid crystal display device.

Further, as shown in FIG.
The seal 14b may have a linear shape. That is, even if the device ID seal 14b of one seal application device is linear, the device ID seals 14b of the other three seal application devices are all bent. For this reason, even if the linear device ID seal 14b is applied, the abnormal seal application device can be specified by looking at the device ID seal 14b.

(Second Embodiment) A second embodiment is a modification of the first embodiment, and is a device I having the same shape.
The application position of the D seal is changed for each seal application device.

More specifically, as can be seen from FIGS. 6 (a) to 6 (d), the device ID seal 14b having the same shape is changed to lower right, upper right, upper left and lower left for each of four seal coating devices. Coated. That is, the device ID seal 14b is applied by changing the application position on the transparent substrate 10 for each of the seal application devices 1 to 4.

As described above, according to the second embodiment of the present invention, the application position of the device ID seal 14b is changed for each seal application device. The seal application device to which the device ID seal 14b has been applied can be specified. That is, it is possible to specify the seal coating device to which the main seal 12 has been applied. For example, when the device ID seal 14b is applied to the lower right of the transparent substrate 10, it is understood that the main seal 12 and the auxiliary seal 14 have been applied by the seal application device 1, and the device ID
When the seal 14b is applied to the upper right of the transparent substrate 10, it can be seen that the main seal 12 and the auxiliary seal 14 are applied by the seal applying device 2. That is, in addition to the effects of the first embodiment, an abnormal seal coating device can be specified more quickly and accurately.

(Third Embodiment) The third embodiment is also a modification of the first embodiment, in which the shape of the device ID seal is a waveform and the number of waveforms is changed for each seal coating device. is there. Then, the number of the waveforms is made to coincide with the number of the seal coating device. Thus, when there is an abnormality in the sealing process, it is possible to identify the abnormal seal applying apparatus only by counting the number of waveforms of the apparatus ID seal.

More specifically, as can be seen from FIG. 7, the device ID seal 1 applied to the lower right of the transparent substrate 10 in FIG.
The shape of 4b is a waveform. And this device I
The number of waveforms of the D seal 14b is made to match the number of the seal coating device 1 to the seal coating device 4. That is, as can be seen from FIG. 7A, when the main seal 12 and the auxiliary seal 14 are applied by the seal applying apparatus 1, the number of waveforms of the apparatus ID seal 14b is reduced to one. FIG.
As can be seen from (b), when the main seal 12 and the auxiliary seal 14 are applied by the seal application device 2, the number of waveforms of the device ID seal 14b is set to two. Similarly, FIG.
In FIG. 7D, the number of waveforms is three, and in FIG. 7D, the number of waveforms is four.

As described above, in the third embodiment of the present invention, the shape of the device ID seal 14b is a waveform,
The number of waveforms was changed for each seal coating device. In addition, the numbers of the seal coating devices 1 to 4 are matched with the number of waveforms. For this reason, even when an abnormality is found in the sealing process in the inspection in the sealing process, the seal applying device having the abnormality can be identified only by looking at the number of waveforms of the device ID seal 14b. For example, device ID
When the seal 14b has a waveform having one waveform, it is understood that the main seal 12 and the auxiliary seal 14 have been applied by the seal coating device 1, and the device ID seal 14b has a waveform having two waveforms. In case, this sticker 1
It can be seen that the seal 2 and the auxiliary seal 14 are applied by the seal applying device 2. Thus, the device ID seal 14b
By simply counting the number of waveforms, it is possible to know the seal coating device to which the main seal 12 and the auxiliary seal 14 have been applied, so that it is possible to quickly and accurately specify the abnormal seal coating device. That is, in addition to the effects of the first and second embodiments described above, the number of the seal coating device can be specified by the number of waveforms of the device ID seal 14b, so that an abnormal seal coating device can be specified quickly and accurately.

FIGS. 8 and 9 show a further modification of the third embodiment. FIG. 8 shows that the position of the waveform of the device ID seal 14b is changed for each seal coating device.
The shape of the device ID seal 14b is different. FIG. 9 shows the device ID by changing the size of the waveform of the device ID seal 14b for each seal coating device.
The shape of the D seal 14b is different.

(Fourth Embodiment) The fourth embodiment is a modification of the above third embodiment, in which the device ID seal is not a waveform but a broken line. And the number of straight lines formed by this device ID seal,
Match the number of the seal coating device. Thus, when there is an abnormality in the sealing process, it is possible to identify the seal applying apparatus having the abnormality simply by counting the number of straight lines of the apparatus ID seal.

More specifically, as can be seen from FIG.
An apparatus ID seal 14b is applied to the lower right of the transparent substrate 10 in the drawing. The device ID seal 14b has a broken line shape, and the number of straight lines formed by the device ID seal 14b matches the number of the seal coating device. That is, as can be seen from FIG. 10A, when the main seal 12 and the auxiliary seal 14 are applied by the seal applying device 1, the shape of the device ID seal 14b is set to one linear shape. Also, as shown in FIG.
The main seal 12 and the auxiliary seal 14 by the seal coating device 2
Is applied, the shape of the device ID seal 14b is set to two linear shapes, that is, one wavy line shape. further,
As can be seen from FIG. 10C, when the main seal 12 and the auxiliary seal 14 are applied by the seal applying device 3, the shape of the device ID seal 14b is changed to three linear shapes, that is,
There are two wavy lines. Similarly, when the coating is performed by the seal coating device 4, the shape is four linear shapes, that is, three wavy shapes.

As described above, according to the fourth embodiment of the present invention, the shape of the device ID seal 14b is a broken line. By counting the number of straight lines of the seal 14b, it is possible to identify the seal applying apparatus having the abnormality. For example, when the device ID seal 14b is formed by one straight line, the main seal 12 and the auxiliary seal 1 are formed.
4 is applied by the seal applying device 1, and when the device ID seal 14b is formed by two straight lines, the main seal 12 and the auxiliary seal 14 are applied by the seal applying device 2. You can see that. Thus, device I
Since the number of straight lines of the D-seal 14b indicates the seal coating device to which the main seal 12 and the auxiliary seal 14 have been applied, it is possible to quickly and accurately specify the abnormal seal coating device. In addition, since the device ID seal 14b has a dashed shape, that is, a linear shape, the tact time of the process of applying the device ID seal 14b can be improved. That is, the processing time required for applying the device ID seal 14b can be reduced.

FIG. 11 shows a further modification of the fourth embodiment. In FIG. 11, the device ID seal 14
The shape of the device ID seal 14b is different by changing the position of the broken line b in each seal coating device.

(Common to First to Fourth Embodiments) The present invention is not limited to the above embodiment, but can be variously modified. For example, the main seals 12, 12 and the auxiliary seals 14, 14, 1
It is not always necessary to apply 4 and 14 simultaneously. That is, before assembling the transparent substrate 10 and the array substrate 16, the auxiliary seals 14, 1
4, 14, and 14 alone may be applied. Furthermore, in the above-described first, third, and fourth embodiments, the device ID seal 14b
In the second embodiment, the application position of the device ID seal 14b is made different by making the shape of the seal different, so that the seal application device to which the main seal 12 and the auxiliary seal 14 are applied can be specified. Is the device ID
By making both the shape and the application position of the seal 14b different, it is also possible to specify the seal application device to which the main seal 12 and the auxiliary seal 14 have been applied. That is, the first, third, and fourth embodiments can be combined with the second embodiment. In addition, in each of the above-described embodiments, one of the auxiliary seals 14, 14, 14, 14 is the device ID seal 14b, but the number of the device ID seal 14b does not need to be one. That is, a plurality of device ID seals 14b such as two, three, etc. may be provided.

In the above embodiment, the main seal 12
Although the seal 12 and the auxiliary seals 14, 14, 14, 14 are applied to the transparent substrate 10, the main seals 12, 12, and the auxiliary seals 14, 14, 14, 14 may be applied to the array substrate 16. Further, the main seals 12, 12 and the auxiliary seals 14, 14, 14, 14 may be applied to different substrates. That is, as a result, between the transparent substrate 10 and the array substrate 16, the main seals 12 and 12 and the auxiliary seal 1
4, 14, 14, and 14 are formed to form the main seal 1.
It suffices that the transparent substrate 10 and the array substrate 16 are adhered to each other by 2 and 12, and that the liquid crystal is sealed between them.

In the above embodiment, the gap holding material 11 is sprayed on the transparent substrate 10, but may be sprayed on the array substrate 16. Further, instead of spraying the gap holding material 11, the gap holding material 11 can be formed on the transparent substrate 10 or the array substrate 16 in advance. That is, as a result, the transparent substrate 10
Alternatively, it is sufficient if the gap holding material 11 is provided on any of the array substrates 16.

Further, in the above embodiment, the transparent substrate 10
By cutting one intermediate device for a liquid crystal display device in combination with the array substrate 16, two liquid crystal display devices can be manufactured. However, the present invention is not limited to this number. By cutting the intermediate device for a display device, one, four, twenty-five, etc. liquid crystal display devices can also be manufactured. The number of auxiliary seals 14 is not limited to four, but may be two, six, eight, or the like.

In the above embodiment, the thin film transistor (T
Although the case where the present invention is applied to a liquid crystal display device that drives liquid crystal by FT) has been described, the present invention can be applied to a liquid crystal display device of another driving method. For example, a liquid crystal display device that drives liquid crystal with a thin film diode (TFD), or a liquid crystal display device that drives a liquid crystal by applying an electric field parallel to the array substrate by providing both a thin film transistor and an electrode facing the thin film transistor on the array substrate Can also be applied. That is, it is sufficient that the array substrate 16 is provided with any liquid crystal driving circuit for driving the liquid crystal.

[0037]

According to the liquid crystal display of the present invention, since the auxiliary seal is applied to the array substrate or the transparent substrate so that the auxiliary seal is higher than the main seal, the displacement caused when assembling the array substrate and the transparent substrate is achieved. Thereby, the alignment of the liquid crystal is not disturbed. In addition, since the device ID seal for specifying the seal applying device to which the auxiliary seal has been applied is applied, even if there is an abnormality in the sealing process, the abnormal seal applying device can be identified quickly.
