Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a liquid crystal display panel, and more particularly to a method of manufacturing a liquid crystal display panel which can obtain a liquid crystal display panel having a uniform cell gap.

[0002]

2. Description of the Related Art Conventionally, as a manufacturing method relating to a seal forming process, a laminating process and a dividing process of a liquid crystal display panel, a method disclosed in, for example, Japanese Patent Laid-Open No. 5-188387 has been proposed.

This method is for preventing a pair of electrode substrates from peeling off as a seal portion on a portion of one electrode substrate which will be a liquid crystal display panel and on a portion to be cut and removed outside the liquid crystal display panel. As the auxiliary fixing portion, a thermosetting adhesive mixed with a hard spacer such as glass beads is applied and formed by screen printing or a dispenser.

After relatively soft spacers such as plastic beads are scattered on the other electrode substrate,
An ultraviolet curable adhesive is applied as a temporary fixing portion when the pair of electrode substrates are bonded to the outer portion of the liquid crystal display panel to be cut and removed.

After that, both electrode substrates are positioned and bonded to each other, and ultraviolet rays are irradiated to cure the ultraviolet curable adhesive to temporarily fix the pair of electrode substrates. A plurality of sets of a pair of electrode substrates in this state are stacked and heated under pressure to cure the thermosetting adhesive to obtain a predetermined cell gap.

After that, a pair of electrode substrates are scribed,
This is a method of separating into a liquid crystal display panel and a portion outside the liquid crystal display panel by breaking.

The auxiliary fixing portion is necessary for the following reasons. In order to divide and remove the outer portion of the liquid crystal display panel, first, one electrode substrate is scribed and broken. However, at this time, the temporary fixing portion may be broken, and a pair of electrodes is formed on the outer portion of the liquid crystal display panel. The electrode substrate may peel off.

When the pair of electrode substrates are peeled off on the outer portion of the liquid crystal display panel, the electrode terminals are damaged by the peeled electrode substrate, or when the other electrode substrate is scribed and broken, it is necessary to attach the peeled electrode substrates. Therefore, the workability is deteriorated. An auxiliary fixing portion is provided to solve these problems.

As shown in FIG. 10, in the above method, the seal portion 52 of the liquid crystal display panel 51 and the liquid crystal display panel 5 are used.
The positional relationship between the auxiliary fixing portion 53 and the temporary fixing portion 54 formed on the outer side portion of No. 1 and the scribe line 55 that separates the liquid crystal display panel 51 from the outer side portion of the liquid crystal display panel 51 is as follows.

The auxiliary fixing portion 53 has a seal portion 52 adjacent thereto.
1-2 pieces are formed in the same width as the seal portion 52 in parallel with
In the case of a book, it is formed in the vicinity of the seal portion 52, and in the case of two, it is formed in the vicinity of the seal portion 52 and the vicinity of the temporary fixing portion 54. The linear auxiliary fixing portion 53 is discontinuous at the portion intersecting the scribe line 55.

The temporary fixing portion 54 is formed at a position outside the auxiliary fixing portion 53. Further, the temporary fixing portion 54 is often formed near the scribe line 55 without intersecting the scribe line 55.

[0012]

In the above method, the temporary fixing portion has a diameter of, for example, about 5 m after the bonding step is completed.
The circular shape of m has a thickness of 10 μm or more, which is considerably thicker than the cell gap of the liquid crystal display panel, for example, 6 μm. Since the temporary fixing portion is already hardened by ultraviolet rays to be shaped like a pillar before being heated under pressure, the liquid crystal display panel of the liquid crystal display panel has one or two linear auxiliary fixing portions. It has been found that the cell gap rapidly increases in the vicinity of the temporarily fixed portion as it moves inward from the seal portion.

Further, when the temporary fixing portion is near the scribe line, the linear auxiliary fixing portion is discontinuous near the scribe line. Therefore, the discontinuous portion extends to the inside of the liquid crystal display panel. It was found that the influence of the stress strain caused by the temporary fixing portion is transmitted, and the cell gap varies near the corner portion of the liquid crystal display panel.

Here, the temporary fixing portion becomes like a pillar,
Since the temporary fixing part made of the ultraviolet curable adhesive is cured in a state where the pair of electrode substrates are bonded together at a low pressure,
This is because the thickness of the temporary fixing portion is not thinned to a predetermined cell gap of the liquid crystal display panel, and the thickness of the temporary fixing portion does not reach the predetermined cell gap of the liquid crystal display panel even by subsequent heating under pressure. Be considered.

Further, the cell gap of the liquid crystal display panel rapidly increases in the vicinity of the temporary fixing portion as it moves away from the seal portion inward because the temporary fixing portion has a wide area and a large thickness. It is considered that this is because the large variation in the distance between the pair of electrode substrates between the seal portion and the seal portion overlaps with each other, and the electrode substrate is in a wavy state.

The present invention has been made in view of the conventional problems as described above, and provides a method of manufacturing a liquid crystal display panel which solves a variation in cell gap due to stress distortion or the like caused by a temporary fixing portion. Is intended.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a sectional view of an essential part of an STN type color liquid crystal display panel manufactured by the method for manufacturing a liquid crystal display panel of the present invention.

As shown in FIG. 1, a pair of glass substrates 1,
2 are arranged facing each other. On the glass substrate 1, R
(Red), G (green), B (blue) picture element 3a and picture element 3a
A color filter composed of a black mask 3b formed between them, an overcoat film 4 functioning as a protective film for the color filter, a transparent display electrode 5 composed of ITO,
In addition, the alignment film 6 is formed in order. On the glass substrate 2, a transparent display electrode 7 made of ITO, an insulating film 8 and an alignment film 9 are sequentially formed.

The pair of glass substrates 1 and 2 on which these various functional films are formed are attached to each other via a seal portion 10 arranged on the periphery of the glass substrates 1 and 2. In this embodiment, a thermosetting type one-component epoxy material is used as the seal portion 10. An in-seal spacer 11 is arranged in the seal portion 10, and an in-cell spacer 13 is arranged in the liquid crystal layer 12 to control a gap (cell gap) between the glass substrates 1 and 2.

Here, these materials will be described.
Glass substrates 1 and 2 have outer dimensions of 370 mm x 480 m
The glass substrate 1 is used as a color filter substrate having a color filter, using soda glass having a thickness of 0.7 mm and a thickness of 0.7 mm. Stripe-shaped display electrodes 5 and 7 are formed on the liquid crystal layer 12 side of the glass substrates 1 and 2 in a direction perpendicular to each other so that two liquid crystal display panels can be taken from the glass substrates 1 and 2 having the above-described dimensions. To manufacture.

Epoxy resin struct bond XN-21-S made by Mitsui Toatsu Kagaku Co., Ltd. is used for the seal portion 10, and glass beads which are hard spacers are used for the spacer 11 in the seal. A plastic substrate may be used instead of the glass substrates 1 and 2.

The method of manufacturing the STN type color liquid crystal display panel shown in FIG. 1 will be described below, focusing on the bonding step according to the present invention.

As described above, the pair of glass substrates 1, 2
After the alignment films 6 and 9 are formed on the transparent display electrodes 5 and 7 and the like, and the alignment treatment is performed, the glass substrate 1 on which the color filter is formed is heated as a seal portion 10 and an auxiliary fixing portion. A glass bead, which is a hard spacer, is mixed into the curable adhesive as the in-seal spacer 11 and is applied by a screen printing method.

On the other glass substrate 2, plastic beads, which are soft spacers, are placed inside the cell spacers 13.
As a temporary fixing part, an ultraviolet curable resin is applied near the scribe line.

As shown in FIG. 2, the auxiliary fixing portion 14 is formed in a shape in which circular points are regularly arranged.

As shown by the hatched area in FIG. 3, the auxiliary fixing portion 14 (not shown in FIG. 3) is formed only in the dummy color filter area 16 formed in the outer area of the liquid crystal display panel 15. However, the auxiliary fixing portion 14 is not formed between the liquid crystal display panel 15 and the scribe line 17.

This is because if there is a step between the inside of the liquid crystal display panel 15 and the area outside thereof depending on the presence or absence of the color filter, the uniformity of the cell gap is impaired, so that the color filter is formed in the liquid crystal display panel 15. If
The auxiliary fixing portion 14 is not formed in a portion of the outer region where the color filter is not formed.

The color filters formed in the dummy color filter region 16 may be of a plurality of colors or a single color, and may or may not have a black mask. Furthermore, the black mask alone may be used.

The diameter of the auxiliary fixing portion 14 is equal to that of the seal portion 1.
It is designed to have the same width as 0, for example, 0.4 mm, and the distance between the respective auxiliary fixing portions 14 is designed to be 2 mm in consideration of printability of screen printing. Further, the auxiliary fixing portion 14 is formed so as to avoid the scribe line 17, and the area where the auxiliary fixing portion 14 is formed occupies more than half of the area between the temporary fixing portion 18 and the seal portion 10.

The region where the auxiliary fixing portion 14 is formed is not simply the area of the auxiliary fixing portion 14 added, and the width is from the outermost auxiliary fixing portion 14 to the innermost auxiliary fixing portion 14. In the area, the distance between the auxiliary fixing portions 14 is also included.

The auxiliary fixing portions 14 are preferably formed in rows as shown in FIG. However, when only one row is formed as shown in FIG. 4, the stress strain due to the temporary fixing portion 18 and the wavy state of the glass substrates 1 and 2 cannot be sufficiently relaxed.

That is, the large cell gap in the temporary fixing portion 18 has an appropriate value in the auxiliary fixing portion 14 portion, but since the auxiliary fixing portion 14 is one row, the cell gap is in the auxiliary fixing portion 14 portion. By the recoil corrected to an appropriate value, the row of the auxiliary fixing portions 14 serves as a fulcrum, and the cell gap in the liquid crystal display panel 15 increases.

Further, as shown in FIG. 5, the auxiliary fixing portion 14
When two rows are formed, the stress strain due to the temporary fixing portion 18 and the wavy state of the glass substrates 1 and 2 can be improved as compared with the case of one row, but they are not yet satisfactory.

That is, the same phenomenon as in the case of the above-described one row occurs, and the sagging phenomenon occurs between the two rows of the auxiliary fixing portions 14. The cell gap in the liquid crystal display panel 15 is closer to an appropriate value than in the case of one column, but it is not yet satisfactory.

Therefore, as shown in FIG. 6, the auxiliary fixing portion 1
When 4 are formed in 3 rows, the stress strain caused by the temporary fixing portion 18 and the wavy state of the glass substrates 1 and 2 are absorbed by the auxiliary fixing portion 14 and can be sufficiently relaxed.

In other words, the cell slack phenomenon in the case of the two rows is corrected by the middle one row of the three rows of the auxiliary fixing portions 14, so that the cell gap in the liquid crystal display panel 15 should be set to a proper value. Can be done. The effect of the rows of the auxiliary fixing portions 14 becomes greater as the number of rows is increased.

Then, a pair of these glass substrates were attached to each other and heated and pressurized at 180 ° C. and 0.8 kg / cm ² ,
After-baking is performed to complete the bonding process.

At this time, the cell gaps at the portions a to g shown in FIG. 7 were measured, and the results are shown in Table 1. Note that the normal cell gap refers to the distance between the pair of glass substrates inside the liquid crystal display panel 15, but in the present embodiment, the distance between the pair of glass substrates outside the liquid crystal display panel 15 is also the cell gap for the sake of simplifying the description. I will call it.

[0055]

[Table 1]

As shown in Table 1, a near the temporary fixing portion 18
The cell gap of the liquid crystal display panel 1 is 11.81 μm, and the cell gap of the auxiliary fixing portion 14 at b is 6.37 μm.
5, the cell gap at c is 6.50 μm and the cell gap at d is 6.
The cell gap at 81 μm and e is 7.25 μm, the cell gap at f is 7.99 μm, and the cell gap at g is 8.88 μm. This is a case where the cell gap after injection of the liquid crystal material is designed to be 6.50 μm.

After that, the liquid crystal display panel 15 is divided along the scribe line 17 and a liquid crystal material is injected to complete the liquid crystal display panel 15. When injecting the liquid crystal material, pressure is applied from both sides of the liquid crystal display panel 15 in contact or non-contact, and the surplus liquid crystal material is discharged from the liquid crystal display panel 15 to control the cell gap, which is called pressure sealing. By using the method or the like, the cell gap after the injection of the liquid crystal material can be made to be around the design value of 6.50 μm.

From the seal portion 10 after the liquid crystal material is injected,
The cell gap in the liquid crystal display panel 15 at a distance of -20 mm was measured, and the results are shown in Table 2 and FIG.
In addition, this measurement part is a part different from the above a to g.

[0059]

[Table 2]

As shown in Table 2 and FIG.
As a result of measuring the cell gap in the liquid crystal display panel 15 up to a distance of 20 mm for every 1 mm away from 0 toward the central part, a cell gap of around 6.50 μm can be obtained in any part.

Here, as a comparative example, the same operation as in the present embodiment is performed except that the auxiliary fixing portion is formed into two linear shapes. The width of the auxiliary fixing part is 0.4 mm, which is the same as the width of the sealing part.
And so as to avoid the scribe line. And the portions corresponding to the above a to g are indicated by a1 to g1,
The cell gap at this point was measured and the results are shown in Table 3.
Shown in.

[0062]

[Table 3]

As shown in Table 3, the cell gap at a1 is 12.39 μm and the cell gap at b1 is 6.64 μm.
The cell gap at m and c1 is 6.55 μm, the cell gap at d1 is 7.64 μm, the cell gap at e1 is 8.37 μm, the cell gap at f1 is 9.29 μm,
The cell gap at g1 is 10.43 μm. This is a case where the cell gap after injection of the liquid crystal material is designed to be 6.50 μm as in the present embodiment.

Thereafter, the liquid crystal display panel is divided along a scribe line, and a liquid crystal material is injected to complete the liquid crystal display panel. When injecting the liquid crystal material, the cell gap after injecting the liquid crystal material can be set to around the design value of 6.50 μm by using the above-mentioned method called pressure sealing, but f1 and g1 The cell gap at will be slightly larger.

From the sealing portion after the liquid crystal material is injected, 1 to 2
The cell gap in the liquid crystal display panel at a distance of 0 mm was measured, and the results are shown in Table 4 and FIG. Note that this measurement portion is a portion different from the above a1 to g1.

[0066]

[Table 4]

As shown in Table 4 and FIG. 9, the cell gap in the liquid crystal display panel was measured up to a distance of 20 mm every 1 mm away from the seal portion toward the central portion. Is adjusted to around 6.50 μm, the cell gap in the vicinity of the seal portion is conversely reduced.

As described above, according to the present embodiment, the degree of swelling of the cell gap, which increases as the distance from the seal portion 10 toward the central portion of the liquid crystal display panel 15, is improved, and the temporary fixing portion 18 and the auxiliary portion are provided. Variations in the cell gap due to the corrugated state of the glass substrate due to the fixed portion 14 and stress strain are reduced.

In the present embodiment, the temporary fixing portion 1
Although 8 is formed in the vicinity of the scribe line 17, the variation in the cell gap can be similarly reduced by forming the temporary fixing portion 18 at a position apart from the scribe line 17.

The present invention is a liquid crystal display panel that is significantly affected by display characteristics due to variations in cell gap, and more specifically, a liquid crystal display panel requiring a cell gap accuracy of ± 0.1 μm or less. By applying the liquid crystal display panel utilizing the interference effect of the above or an IPS type TFT drive liquid crystal display panel or the like, a liquid crystal display panel having few display characteristic defects such as display color unevenness defect, domain defect, contrast defect or response defect can be obtained. Obtainable.

In the present invention, the accuracy of the cell gap is ±
As a matter of course, it can be applied to a liquid crystal display panel that does not require 0.1 μm or less, for example, a TN type TFT drive liquid crystal display panel.

[0072]

As described above, according to the method of manufacturing a liquid crystal display panel of the present invention, the auxiliary fixing portions having a predetermined shape are uniformly dispersed to form a columnar shape. A liquid crystal display panel having uniform characteristics of display color, contrast, response speed, etc. in the display surface because stress strain caused by the stopper can be uniformly dispersed and influence on the liquid crystal display panel can be mitigated. Can be obtained.

Further, since the auxiliary fixing portion has a circular shape, the stress strain described above can be dispersed isotropically,
Since it is possible to further alleviate the influence on the liquid crystal display panel, it is possible to obtain a liquid crystal display panel having display color, contrast, response speed, and the like that are more uniform within the display surface.

Further, by forming the auxiliary fixing portion so as not to straddle the scribe line, that is, the auxiliary fixing portion is not cut off so as not to straddle the scribe line, but the auxiliary fixing portion formed uniformly dispersed. By positioning the scribe line in the gap between the parts, it is possible to prevent the cell gap near the scribe line from increasing. Further, since bending stress is uniformly applied to the electrode substrate when breaking after scribing, the sectional surface of the electrode substrate along the scribe line is clean, and the cutting accuracy can be improved.

Further, since the outer dimensions of the auxiliary fixing portions are equal to or smaller than the width of the sealing portion, the contact area between each auxiliary fixing portion and the electrode substrate can be reduced, and the stress strain can be reduced. .

Further, the area forming the auxiliary fixing portion is
By forming the width to be half or more of the distance from the temporary fixing portion to the shortest distance sealing portion, the stress strain and the corrugated state of the electrode substrate can be relaxed.

Further, the auxiliary fixing portions are formed in rows, and three or more rows of auxiliary fixing portions are formed between the temporary fixing portion and the seal portion which is the shortest distance from the temporary fixing portion. The stress strain and the wavy state of the electrode substrate can be further relaxed.

When the functional film is formed on the pair of electrode substrates, the auxiliary fixing portion is formed only on the functional film having a thickness almost equal to the thickness of the functional film formed in the region to be the liquid crystal display panel. By doing so, the cell gap can be made uniform without being affected by the thickness of the functional film.

Further, since the functional film includes the color filter, the color filter has a thickness of 1 to 2 μm, which is thicker than other functional films, so that the effect of making the cell gap uniform becomes more remarkable. .
