Abstract

On the surface of an array substrate 60, a sealing material 64 is provided so as to surround a display region, and a plurality of spacers 66 are provided in the display region. The array substrate 60 and a counter substrate 62 are vacuum held to stages 20 and 18, respectively, so that the array substrate 60 and the counter substrate 62 face each other. In one of the stages, a recessed portion 26 facing the effective region of the counter substrate 62 is formed. By evacuating the recessed portion, the effective region of the counter substrate 62 is deflected so as to go away from the effective region of the array substrate 60. In this state, the peripheral portions of the array substrate 60 and the counter substrate 62 are panel aligned with each other via the sealing material 64. Subsequently, the counter substrate 62 is positioned with respect to the array substrate 60 by means of an X-Y-θ stage. Thereafter, the deflection of the counter substrate 62 is removed to cause the counter substrate 62 and the array substrate 60 to contact each other via the spacers 66. Thus, it is possible to provide an assembling method and apparatus, which can assemble a flat display panel without making scars on a glass substrate.

(Conventional technology) Liquid crystal display devices have advantages such as being thin, light, and low in power consumption. Therefore, they are widely used as display devices for notebook or sub-notebook personal computers. In recent years, along with the improvement of the performance of personal computers, it has been required to increase the display capacity or display area of the display and to improve the picture quality. A liquid crystal display device is constituted by closely bonding two glass substrates via a spacer and sealing liquid crystal molecules between the glass substrates. Generally, a liquid crystal display device is assembled by the following process. That is, first, the next pair of stages (S t a g e) that are opposed to each other adsorb and hold the glass substrates, respectively. At this time, a plurality of electrodes are formed on the surface of the glass substrate held on the lower stage, and a rectangular frame-shaped sealing material defining a display area and a spacer for maintaining a gap between the two glass substrates are arranged. The glass substrate held on the upper stage is provided with a counter electrode and a color filter. In this state, after the two glass substrates are relatively lowered onto the stage with a predetermined gap therebetween, the two glass substrates are positioned using the predetermined alignment marks as a reference through the movement of the upper stage in the X, Y direction and rotation around the Z axis.

At this time, due to the resistance when the two glass substrates are in contact through the spacer or the sealing material; or the rigidity and parallelism of the upper and lower drives of the upper and lower stages, and even the backlash of the X, γ, 0 drive mechanism, etc. Subtle misalignment occurs between substrates. In this way, in a state where the two glass substrates are in contact with each other via the sealing material and the spacer, the upper stage is moved in the X, γ, and Θ directions to perform positioning. After the alignment is completed, the gap between the two glass substrates is pressed to a predetermined value, and liquid crystal molecules are sealed between the glass substrates.

At the same time, there is a risk of being trapped in the color filter layer. As described above, as described above, in recent years, liquid crystal display devices have been strongly expected to raise images. Therefore, even slight flaws in the manufacturing method are regarded as poor image quality, which is a factor for reducing the manufacturing yield. The present invention has been made by the present invention in view of the foregoing points, and an object thereof is to provide a device and an assembling method which do not hurt the assembling of these substrates when assembling a pair of substrates.

Description of Invention (8) / 1 If the liquid crystal display device assembled with the above configuration, the array substrate and the It can also be used to move the substrates in contact with each other in the sealing material portion to the substrate. At this time, damage to the alignment film and the like can be completely resolved, and a high manufacturing yield can be ensured. For example, in the conventional method, about 50% or more of the products were found to have the brightest part of the defect based on the misalignment caused by the damage of the alignment film at least 10 or more (the applied voltage is not black but light is often transmitted through) The defects shown in the white), but in accordance with the present invention substantially solve the defects caused by the damage of the alignment film. On the other hand, when a lower stage having no recessed portion is used, the array substrate and the opposing substrate are opposed to each other, and when the sealing material portion is in contact with each other, the substrates are attracted to each other through the spacer, and the state cannot be re-aligned. In addition, even if the alignment is performed, the alignment film is damaged due to the sliding of the spacers with each other, and the problem of display failure occurs, which is extremely low as a yield rate of about 10%.

The height of the table body 22 is set to be approximately 1 to 5 0 // m lower than the substrate holding surface 1 4 a. The array substrate 1 is placed on the lower stage 6, but the downward deflection ′ caused by the self-weight of the array substrate 1 is suppressed as much as possible by raising the support of the stage 20.

Description of the invention (10) Electrode electrode 4 0 through silicon nitride film 3 8 The insulating film 37 and the gate insulating film 33 reach the semiconductor layer 32. The drain electrode is connected to a signal line (not shown). In addition, a stripe-like surface having a flattened surface is stacked on the entire surface, and each of the colored resins R, G'B is arranged in a color filter layer 4 2 in order, and a pixel electrode 43 is formed on the surface. The pixel electrode system is connected to the contact hole 45 through the source electrode 39 through the source electrode system. The storage capacitor line is electrically connected to the pixel electrode, and a capacitance C s is formed between the semiconductor layer and a layer formed by the same layer through a gate insulating film. On the array substrate 1, a spacer 47 for maintaining a distance between the two substrates 1 and 2 is set in a fixed state. That is, the spacer 4 7 is a square pillar with a diameter of about 20 m formed from a black resin obtained by mixing the resins R, G, and B. The spacers 47 are provided above the scanning lines. The spacer 4 7 is covered by an alignment film 4 8. With this spacer 4 7, the distance between the substrates is maintained at 3 to 4 // m. The opposite substrate 2 facing the array substrate 1 is formed on the glass substrate 51 as the opposite electrode 5 2 and the alignment film 53 are formed in this order. As shown in Fig. 6, a liquid crystal 54 is sealed between these two substrates 2,1. As described above, when the two substrates 1 and 2 are aligned, the spacer 4 7 as described above is fixed to the array substrate 1. Therefore, the conventional spacer 4 7 also hurts the counterpart on the opposite side. The alignment film 53 may face the inner surface of the substrate 2. In order to solve these difficulties, the present invention is aimed at the alignment of two substrates in a state where the two substrates are sealed and bonded, and the distance between the two substrates is in accordance with Chinese National Standard (CNS) A4 (210 X 297) (Mm) -13 First read the item a on the back Λ Write * 1 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 496989 A7 _ B7 V. Description of the invention (11) Implemented in a state with a large gap from the implementation. For example, during alignment, the array substrate 1 as the lower substrate is flexed slightly downwards, so as to prevent the above-mentioned (please read the precautions on the back before filling in this page) the end of the spacer 4 7 and the opposing substrate 2 Inside. Specifically, when the lower array substrate 1 is placed on the lower stage 6, the array substrate 1 is flexed slightly downwards corresponding to the recesses 13 and at the same time, excessive deflection is prevented by raising the stage 20. When the alignment of the two substrates 1 and 2 is performed in this state, the spacers 4 and 7 are aligned under the opposing substrate 2 due to a slight deflection below the array substrate 1. The term "lattice gap" refers to the distance between the two substrates when used as a liquid crystal lattice, which is equal to the height of the spacer. In this way, according to the above embodiment, it is possible to prevent the opposing substrate from being injured. In particular, when the alignment film is formed on the inside of the counter substrate, it is particularly effective because the hardness of the alignment film is weak. That is, an inorganic film such as I T0 is weaker than an alignment film formed of an organic film such as polyimide. The alignment of the two substrates 1 and 2 in steps s 3 and S 5 will be described below. In either step, the following alignment is performed. In step S3, a multi-stage alignment is implemented, but this means that the following alignment is close to the two substrates1 in turn, and it is implemented multiple times by printing 2 in the employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The above-mentioned alignment is performed by sucking the opposite substrate 2 on the upper stage 7 and placing the array substrate 1 on the lower stage. In this state, the upper stage 7 and the lower stage 7, 6 are moved relative to each other, that is, the two substrates 2, 1 are implemented. These alignment systems are shown in Fig. 8. The two substrates 1 and 2 are respectively attached with alignment marks 5 8, 5 9. While observing these marks, the two substrates 1 and 2 are relatively displaced through the two substrates 1 and 2. Implemented. In order to observe these marks, the 7th paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -14-496989 A7 ______ B7 5.

Through these through holes 5 5, 5 5; 5 6 ′ 5 6, it can be observed that the alignment marks 5 8 and 5 8 formed on the two substrates 2 and 1 overlap with each other. In order to perform this observation optically, lamps 60, 60 are provided for the through holes 5 5 and 5 5 of the upper stage 7, and cameras 6 1, 6 are provided below the through holes 56 and 56 of the lower stage 6. 1 ° As can be seen from FIG. 7, the counter substrate 2 is sucked and fixed on the upper stage 7, and the array substrate 1 is placed on the lower stage 6. In this state, the lamps 60, 60 are turned on. The images overlapping the registration marks above and below the lamps 60 and 60 pass through the registration holes 5 6 and 5 6 to transmit the images to the cameras 6 1 and 6 1. As can be seen from FIG. 8, the image is superimposed on the alignment mark 5 8 attached to the upper facing substrate 2 and the alignment mark 5 9 attached to the lower array substrate 1 to become the display as shown in FIG. 9. .

That is, when the total pitch of the two substrates 1 and 2 is not equal, the overlapping image of the two sets of registration marks in such an overlapped state is shown in FIG. 11. At this time, as shown in Figure 12, the X direction is aligned as described above, and the Chinese paper standard (CNS) A4 (210 X 297 mm) is applied to the paper size. -15-496989 A7 V.

That is, when the alignment of the array substrate 1 and the counter substrate 2 is started, first, the amount of offset of the array substrate 1 and the counter i-plate 2 is measured as described above (step 1 1). Then, in order to make the offset amount zero according to the measured distance, the upper substrate is moved in the X, Y, and 0 directions and rotated to perform alignment (step 12). In this way, even if alignment is performed, subtle deviations due to the backlash of the X, Y, and Θ drive mechanisms are generated between the array substrate 1 and the counter substrate 2. Therefore, the array substrate 1 and the counter substrate 2 are measured again. Offset amount (step 1 3).

Then repeat steps 1 3, 1 and 4, if the offset amount of the array substrate 1 and the counter substrate 2 is still outside the specified range, repeat the operations of steps 12 to 14 through step 15 to determine the deviation. The position operation reaches the preset operation time or the preset operation times. Even if the alignment operation reaches the preset operation time or the number of operations set in advance and the offset amount of the two substrates is still outside the specified range, it means that the alignment is not performed normally. Therefore, an error message is output (step 16), and the positioning operation is ended. In this regard, after the alignment operation of step 12 and the offset amount of the array substrate 1 and the counter substrate 2 are within a predetermined range (step 14), the offset of the array substrate 1 and the counter substrate 2 is judged. If the amount is zero (step 17), if it is not zero, it is judged whether the alignment action has not reached the preset action time, or whether it has not reached the preset action times (step 18), and it is judged at step 18 that it has not reached When it is, repeat the alignment action (step 1 2). At this time, the amount of offset that reaches the specified range is input as information. As long as the amount of misalignment does not change to zero, the judgment in step 18 is repeated until the preset action time or the preset number of actions is reached, that is, whenever the misalignment action is repeated; misalignment The magnitude is close to zero. In this way, when the amount of misalignment becomes zero, or when it reaches the preset operation time 'or the preset number of operations, the registration operation ends normally (step 19).

Description of the invention (20) As shown in Figure 7 (c), on the opposite substrate 1 6 2 The state of deflection measured by the number '1' is lowered to the upper stage 1 1 8 until the peripheral edge portion of the counter substrate 16 2 contacts the sealing material 16 4 on the array substrate 16. At this time, since the display area 16 2 a of the opposing substrate 16 2 is flexed in a direction away from the display area 16 0 a of the array substrate 16 0, the display area 16 2 a is not in contact with The spacers on the array substrate are held under 16 6.

Invention description (21) (Please read the precautions on the back before filling out this page) Then, stop the 2nd and 3rd vacuum pumps 136, 143 and release The adsorption of the array substrate 160 and the counter substrate 16 2 also rises to the upper stage 1 1 8 together with X-γ-10 units 1 2 2. Then, the closely-attached array substrate 160 and the counter substrate 16 2 are taken out from the lower stage by a conveying mechanism (not shown), and then are conveyed to the process of curing the sealing material. According to the assembling method and the assembling device of the liquid crystal display device constructed as described above, since the display area 16 a of the counter substrate χ 60 is flexed from the array substrate 16 2 in the direction of departure, only the peripheral edge portion of the counter substrate is sealed through The material 1 6 4 is aligned in a state where it is in contact with the array substrate. Therefore, the display area of the opposite substrate can be positioned in the spacer 1 6 in a non-contact state. In addition, since the substrate holding surface 1 2 0 a of the lower stage 1 2 0 is also provided with a recess 1 3 8, it is possible to prevent the effective area 1 6 of the array substrate 16 from being attached to the substrate holding surface by dust or the like. 0 a is deflected toward the opposite substrate 16 2 side, and at the same time, the effective area 16 0 a of the array substrate 16 is slightly deflected to the concave 1 3 8 side through its own weight and separated from the opposite substrate 16 2.

Description of the invention (22 ) (Please read the note on the back? Matters before filling out this page) The alignment of the substrates with each other, so 'When removing the deflection of the opposing substrate after the alignment, the deviation of the amount of deflection is also considered, but When the deflection amount of the counter substrate is about 5 0 // m, the offset amount is generally about 0 · 02 ~ 0 · 5 // m on a glass substrate of 3 〇 X 3 0 Omm, and it is practical. There will be no problems. Fig. 18 is a schematic view showing an assembling apparatus and an assembling method according to a third embodiment of the present invention, which is still different. According to the second embodiment, an exhaust port 70 is also provided in the recess 1 3 8 of the lower stage 120, and a fourth vacuum pump (not shown) is connected to the exhaust port. At this time, the depression 138 is formed to a depth of 50 // m or more. Similar to the above-mentioned embodiment, after the upper stage 1 18 and the lower stage 1 2 0 adsorb and hold the counter substrate 16 2 and the array substrate 16 0 respectively, the first and fourth vacuum pumps are operated to make the counter substrate effective. 16 2 a and the effective area of the array substrate 16 0 a are flexed in directions away from each other.

Then, the first and fourth vacuum pumps are stopped and the recesses 1 2 6 and 1 3 8 are restored to atmospheric pressure, and the deflections of the counter substrate 16 2 and the array substrate 16 are removed. As a result, the opposing substrate 16 and the array substrate 160 are in contact with each other via the spacer 16 and are attached to each other through a predetermined gap. The other configurations are the same as those of the above-mentioned embodiment, and the same reference numerals are attached to the same portions and detailed descriptions thereof are omitted. This paper size applies to China National Standard (CNS) A4 specification (21〇X 297 mm) -25 _496989 A7, _ B7 V. Description of invention (23) (Please read the note on the back? Matters before filling this page) In the second and third embodiments thus constituted, the same functions and effects as those of the first embodiment can be obtained, and at the same time, the two glass substrates are flexed with only a certain amount, and the flexing is removed. Therefore, the alignment deviation due to deflection can be made zero. 19 to 22 are modified examples of the upper stage 1 1 8 and the lower stage 1 2 0. According to the first modification shown in Fig. 19, a plurality of elongated ribs 1 72 are formed on the bottom surfaces of the recesses 1 2 6 and 1 3 8 of the upper and lower stages, which extend parallel to each other. The height of each rib 1 72 is set to, for example, 50 β m. In the first modification, the substrates 16 and 2 and the array are opposed to each other through the depressions 1 2 6 and 1 3 8 at a predetermined pressure. The substrate 160 is bent toward the bottom side of the recess. It is in a state of being in contact with the ribs 172. In such a configuration, by adjusting the height of the ribs 172, the amount of deflection of the glass substrate can be constantly made constant, and the exhaust pressure can be easily controlled. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in accordance with the second modification shown in Fig. 20, the recesses of each station 1 2 6 '1 3 8' are flat and continuous to form a substrate holding surface continuous to the station. Spherical. According to this configuration, when the glass substrate is bent, it is possible to prevent the glass substrate from being concentrated on the boundary between the substrate holding surface and the recess of the stage. Thereby, it is possible to prevent the peripheral edge portion of the falling glass substrate from being sucked and held, and the peripheral edge portion to jump off the substrate holding surface. Since it is extremely difficult to process a recess having a spherical bottom surface as described above, as in the third modification shown in FIG. 21, a plurality of elongated ribs 17 extending in parallel with each other are formed on the bottom surface of the recess, as shown in FIG. 2, and apply these ribbed paper sizes to Chinese National Standard (CNS) A4 specifications (210 X 297 mm) _ 26 _ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 496989 A7 _, B7 V. Description of the invention (24 ), The ribs located at the center of the recess are the lowest, and as the height of the ribs becomes higher toward the periphery of the recess, a pseudo curved surface shape may be formed. In addition, as shown in the fourth modified example in Fig. 22, instead of the ribs, a plurality of protrusions 74 having a square pillar shape are formed on the bottom surface of the recess. It is also possible to form the projection located at the center of the recess to a minimum, and to increase the height toward the periphery of the recess to form a pseudo-curved shape. Even when the tables of the first to fourth modified examples configured as described above are used, the same effects as those of the above embodiment can be obtained. In addition, when using such a modified stage, the glass substrate is kept in contact with the ribs 1 72 and the bottom surface of the recess is protruded in a state where the glass substrate is flexed. Therefore, the glass substrate can be omitted. The exhaust system of the substrate's peripheral edge is adsorbed on the substrate holding surface of the stage. Only the exhaust system for flexing the glass substrate is formed, and the adsorption and holding of the glass substrate can be combined. In addition, the present invention is not limited to the above-mentioned embodiments and modified examples, and various modifications can be made within the scope of the present invention. For example, the shape and size of the recesses formed on the upper stage and the lower stage, and the size of the glass substrate Various modifications can be made as needed. In addition, the present invention is not limited to a liquid crystal display device having spherical spacers, but can also be applied to the assembly of a liquid crystal display device having columnar spacers erected in an effective field through a photolithographic process. In the above-mentioned embodiment, the structure is such that the substrate is moved to perform the alignment after at least one of the array substrate and the opposing substrate is adhered via the sealing material, but it is not limited to this, and may be Create the following assembly method. That is, in the state where at least one of the array substrate and the counter substrate is flexed, the substrates are close to each other, and the paper is moved in the close state. The Chinese standard (CNS) A4 specification (210 X 297 mm) is applicable. 27 ------? —.—------- Order '— ^ ----- line (Please read the note on the back?

Description of the invention (25) At least one substrate is used to align the substrates with each other. As a result, after the alignment, the array substrate and the counter substrate are adhered to each other through a sealing material, and then the substrate can be brought into contact with the array substrate and the counter substrate via a spacer through the deflection of the substrate. According to this structure, even if the substrates are aligned with each other in a state close to the array substrate and the counter substrate, the display areas are not brought into contact with each other through the spacer, and damage to the display area by the spacer can be prevented. . Therefore, it is possible to provide a liquid crystal display device capable of preventing poor alignment due to damage and image defects and improving image quality. In addition, by performing alignment in a state close to the array substrate and the counter substrate, high-precision alignment can be formed, and image quality can be further improved. In addition, in the above-mentioned embodiment, the configuration for assembling a liquid crystal display device using a substrate provided on one glass substrate with an effective area is described, but a substrate with a plurality of effective areas provided on one glass substrate is used to simultaneously assemble a plurality of liquid crystal displays. A configuration without a device is also possible. At this time, a plurality of recesses corresponding to the effective area are provided on at least one of the platforms, or a single recess is formed, and a plurality of protrusions are formed in the recesses, and protrusions facing the central portion of each effective area are formed.
