DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter used for an image display panel such as a liquid crystal panel or a plasma display panel, and a display element used for a display device or an optical shutter.

[0002]

2. Description of the Related Art Displays such as liquid crystal panels and plasma display panels are used as display elements for televisions and monitors, and have a structure in which a light control layer is sandwiched between two substrates.

In a conventional method of manufacturing a liquid crystal panel, an array substrate is manufactured by repeating a film forming process and a photolithography process on one glass substrate, and a color filter is formed on the other substrate (counter substrate). A seal is printed (or drawn) on one of the substrates, the array substrate and the opposing substrate are bonded together, and after the seal is cured, liquid crystal (light control layer) is injected from the injection port, and the injection port is sealed. It was to be sealed with resin.

[0004] As shown in FIG. 17, a display element such as a liquid crystal panel has been used to form one element (FIG. 17a) or a plurality of elements (FIG. 17b) on one substrate. However, it was impossible to manufacture an element larger than the size of the original substrate (mother glass) 30 by this method.

Therefore, in order to manufacture a display element having a size larger than the size of the mother glass as shown in FIG. 18, a method has been devised in which two liquid crystal panels are bonded to form a single liquid crystal panel (flat panel display). 1997 p46

[0006]

In a conventional method, a method for manufacturing a seal for each liquid crystal element is to form a thermosetting resin or a photocurable resin as a seal resin 3 around one of the substrates by printing or drawing. After the two substrates are bonded together, the sealing resin 3 is cured by heat or light. Glass beads 7 or SiO ₂ spheres or resin spheres are mixed in the sealing resin 3 in order to maintain the peripheral substrate interval (FIG. 19).

As shown in FIG. 18, when two or more elements are bonded to each other to form one element, the light is not transmitted through the seal portion. If the seal width is large, the display is interrupted at this portion. I see it. In order to eliminate this, it is necessary to make the pixel size larger than the seal width, and it is difficult to display finely.

FIG. 1a) shows a top view of a display element according to the invention.

FIG. 1b) is an enlarged view of the vicinity of the seal in FIG. 1a).

Two or more display elements shown in FIG. 1 are connected to form one display element.

Two display elements A and B shown in FIG. 2A) are bonded together to produce one display element C shown in FIG. 2B). FIG. 2c) is an enlarged view of the vicinity of the seal in FIG. 2b).

FIG. 3 is a sectional view showing the vicinity of the seal of the display element in FIG.

An embodiment of the display device shown in FIGS. 1, 2 and 3, particularly a liquid crystal display device, will be described below.

A video signal line (source) 10 and a scanning signal line (gate) 11 are formed in the form of a matrix on a glass substrate 1 as metal wiring, and a semiconductor layer (TFT: Thin) is formed as an active element (switching element) 12 at the intersection. Film Transi
stor).

The pixel electrode 1 is connected to the active element.
3 is formed of a transparent conductive film (ITO: indium oxide-tin oxide).

Next, an alignment film (AL541) is formed on the substrate 1 on which the array is formed and the opposite substrate 2 on which the color filters are formed.
7: JSR) is printed and cured, and then subjected to a rubbing treatment.

Next, a protrusion 20 is formed in the area of the counter substrate 2 where the seal is to be formed, so as to have a width of 15 μm and a height of 5 μm. Since the width of the black matrix of the color filter is 20 μm, the projections 20 are formed between them. As shown in FIG. 1, the protrusions 20 are continuously formed at the end of the substrate except for the injection port.

As a method for forming the projections 20, a thermosetting resin having adhesiveness was formed in a region where a seal was formed by an ink jet method, and then dried at 100 ° C. for 1 hour to form projections.

Since the adhesive in the projection (resin) is cured at 180 ° C., it does not act as an adhesive at the time when the projection is formed.

Further, a resin ball having a diameter of 5.0 μm (Epostor-GP) is provided as a spacer in the display area on either the array substrate or the counter substrate in order to maintain the substrate interval.
-HC: Nippon Shokubai Co., Ltd.). Thereafter, a conductive paste 4 is applied to the edge of the substrate in order to establish conduction between the array substrate and the opposing substrate.

Thereafter, the substrate 1 and the counter substrate 2 are bonded together (FIG. 3b), and the adhesive in the protrusion is cured by heating at 180 ° C. for 2 hours (FIG. 3c).

A liquid crystal (MT5087: manufactured by Chisso Corporation) was injected into the empty panel prepared as described above by a vacuum injection method (the empty panel was set in a depressurized tank, and the inside of the panel was evacuated. By bringing them into contact and returning the inside of the tank to normal pressure,
Liquid crystal is injected into the panel).

Thereafter, the sealing resin 5 is inserted into the injection port of the liquid crystal panel.
A light curable resin (Loctite 352A: manufactured by Nippon Loctite) is applied to the entire injection port, and light is applied at 10 mW / c
The sealing resin was cured by irradiating at 5 m ² for 5 minutes.

As shown in FIG. 2, a display element B similar to the display element A manufactured in this manner was connected to form one display element C. As shown in FIG. 2, the display elements A and B differ from each other in the portions where the electrodes are taken out.

A polarizing plate (NPF-HEG142) is formed above and below the display element C (outside the glass substrate) thus manufactured.
5DU: manufactured by Nitto Denko).

As a comparative example, as shown in FIG. 19, as a peripheral seal, an ordinary seal resin (epoxy resin) 3 without a projection was used. The manufacturing method is described below.

On one substrate, a glass fiber 7 (PF-50S: Nippon Electric Glass) having a short axis diameter of 5.0 μm mixed with a sealing resin (epoxy resin) 3 is printed by screen printing. Thereafter, both substrates are bonded together, and the sealing resin 3 is cured at 180 ° C. for 1 hour.

At the time of printing, the sealing resin is 0.4 mm.
However, after the two substrates were bonded together and cured, the width spread to about 1.0 mm. Thereafter, as shown in FIG. 18, similar display elements were connected to form one display element.

When the present invention is compared with the comparative example, in the present invention, since the width of the projection 20 can be controlled to 15 μm, the projections 20 fall within the width (20 μm) of the black matrix of the color filter, and the joined portions are inconspicuous. In the comparative example, since the width of the sealing resin was 1.0 mm (1000 μm), the seam was conspicuous. In order to make the seams inconspicuous, the pixel pitch must be widened, and high-definition display cannot be performed.

In order to produce a pixel pitch that does not give a sense of strangeness, the width of the black matrix should be 100 μm or less.
More preferably, it is desirable to set it to 50 μm or less.
That is, it is desirable that the line width of the protrusion is 100 μm or less, more preferably 50 μm or less.

In the present invention, the line width of the protrusion before and after bonding both substrates (the array substrate and the counter substrate) was only 1.13 times from 15 μm to 17 μm.
In the seal resin of the comparative example, the line width of the seal resin before and after bonding both substrates is from 0.4 mm to 1.0 mm and 2.5 mm.
Because it spreads twice, the seal part becomes thicker, and the joint becomes more conspicuous. It is desirable that the spread of the line width before and after bonding the upper and lower substrates is 1.2 times or less.

(Embodiment 2) In the first embodiment, the projections 20 are provided with adhesiveness, but in this embodiment, after the projections are formed as shown in FIG. Formed. Otherwise, a display element and a display element were manufactured in the same manner as in Embodiment 1. The adhesive was also formed by an inkjet method. By doing so, the choice of materials for the protrusions and the adhesive is expanded, and a display element with good adhesion and the like can be obtained.

(Embodiment 3) In the first embodiment, the projections 20 are provided with adhesiveness. In this embodiment, however, the projections are formed as shown in FIG. The agent 21 is poured between the two substrates. Otherwise, a display element and a display element were manufactured in the same manner as in Embodiment 1. By doing so, the choice of materials for the protrusions and the adhesive is expanded, and a display element with good adhesion and the like can be obtained.

(Embodiment 4) A display element and a display element were manufactured in the same manner as in Embodiment 1 except that protrusions were formed on the array side. That is, in the first embodiment, the protrusions 20 are formed on the color filter side as shown in FIG.
In this embodiment, protrusions are formed on the array substrate side as shown in FIG. Even in this case, as in the first embodiment, the width can be reduced as compared with the case where the conventional sealing resin is used, so that a display element with less noticeable joints can be obtained.

(Embodiment 5) In Embodiment 4, the projections 20 are provided with adhesiveness. In this embodiment, after the projections are formed as shown in FIG. Formed. Otherwise, a display element and a display element were manufactured in the same manner as in Embodiment 4. The adhesive was also formed by an inkjet method. By doing so, the choice of materials for the protrusions and the adhesive is expanded, and a display element with good adhesion and the like can be obtained.

(Embodiment 6) In the fourth embodiment, the protrusions 20 are provided with adhesiveness. In this embodiment, however, the protrusions are formed as shown in FIG. The agent 21 is poured between the two substrates. Otherwise, a display element and a display element were manufactured in the same manner as in Embodiment 4. By doing so, the choice of materials for the protrusions and the adhesive is expanded, and a display element with good adhesion and the like can be obtained.

(Embodiment 7) In the first to sixth embodiments, the projections 20 are formed only in the area where the seal is formed, but in the present embodiment, the projections 20 are formed in the area where the seal is formed and the display area. I do.

FIG. 9A is a top view of the pixel portion, FIG. 9B is a sectional view of the pixel portion, and FIG. 9C) is a sectional view of a portion corresponding to a seal.

That is, in the first to sixth embodiments, a resin ball having a diameter of 5.0 μm was sprayed as a spacer for maintaining the distance between the substrates as shown in FIG.
As shown in a) and b), a projection 20 is formed in a portion of the display area which does not hinder display of the pixel portion. FIG.
As shown in c), the projection 20 is also provided on the portion corresponding to the seal.
To form If the projections 20 formed on the display unit are not continuous, liquid crystal can be easily injected.

As described above, the protrusion 2 is formed on the seal portion and the display area.
By forming 0, the spacer can be formed at a time, so that the number of steps can be reduced. Further, since a spacer need not be formed on the pixel electrode, a display with high contrast can be obtained.

(Embodiment 8) In Embodiments 1 to 7, a vacuum injection method is used as a liquid crystal injection method, but in this embodiment, a dropping method is used.

The same process as in the first embodiment is performed until the protrusions 20 are formed on the opposite substrate (color filter-side substrate). Thereafter, as shown in FIG. 10, the protrusions 20 are continuously formed in the region where the seal is formed. In the first embodiment, the injection port is opened, but this is not necessary in the present invention. In addition, a photocurable resin is mixed in the protrusion 20.

Then, after dispersing the spacers, the liquid crystal is dropped onto either the array substrate or the counter substrate in an amount included between the substrates.

Thereafter, the substrate 1 and the counter substrate 2 are bonded together in a low vacuum, and the projections 20 formed on the sealing portion are irradiated with 1500 mj of UV light to cure the projections.

One display element C was manufactured by connecting display elements B similar to display element A manufactured in this manner (FIG. 11). As shown in FIG. 11, the display elements A and B differ from each other in the portions where the electrodes are extracted.

A polarizing plate (NPF-HEG142) is provided above and below (outside the glass substrate) the display element C thus manufactured.
5DU: manufactured by Nitto Denko).

According to the present invention, since the sealing portion can be made smaller, a display element having good display quality in which the joined portions are inconspicuous can be obtained.

After the projections 20 are formed on the array substrate side, they may be bonded and then an adhesive 21 may be injected, or the projections 20 may be formed in the display area as in the seventh embodiment.

In this embodiment, the projections are formed by an ink jet method, but they may be formed by a photolithography method using a photosensitive resin or the like. Further, instead of a resin, an insulating film such as SiNx or SiO ₂ may be formed as the protrusion. By forming with an insulating film such as SiNx or SiO _2, it can be formed by a conventional array process, so that material cost, process equipment, and the like can be reduced.

Although one display element is formed by connecting two display elements, two or more display elements may be connected as shown in FIGS.

Further, the number of one substrate and the number of the other substrate may be different. For example, as shown in FIG. 14, the array side substrate may be two and the opposing side substrate may be one. The reverse is also possible.

In that case, as shown in FIG. 15, either one of the projections at the sealing portion of the joint portion may be sufficient. Further, as shown in FIG. 16, the projection of the seal portion may not be formed at the joint portion.
