The second adhesive layer 252 is formed between the 240, and it is possible to bond the color layer 230 and the electromagnetic shielding layer 240.

In addition, a third adhesive layer 11 may be formed on one surface of the base substrate 120. Here, the third adhesive layer 11 may be an adhesive layer in FIG. 1.

The third adhesive layer 11 may attach the filter 110 to the front substrate 10 of the display panel 100.

In addition, the filter 110 may further include a near infrared ray shielding layer.

In the filter 110 described above, the positions of the color layer 230 and the electromagnetic shielding layer 240 may be changed.

Alternatively, the second substrate 12 may be a substrate included in a touch panel.

For example, as in the case of FIG. 3, the touch panel 310 disposed in front of the display panel 300 includes a lower substrate 12 and an upper substrate 311, and the lower substrate 12 and the upper substrate. The touch devices 312 may be disposed between the 311. The touch element 312 may be at least one of a touch sensor and an electrode. In addition, the lower substrate 12 may be the second substrate of FIG. 1.

In addition, the display panel 300 may be a liquid crystal display panel. The display panel 300 includes a front panel 10, a rear substrate 301, a seal portion 302 disposed between the front substrate 10 and the rear substrate 301, and the front substrate 10 and the rear surface. The liquid crystal layer 03 may be sealed between the substrates 301. Here, the front substrate 10 may be the first substrate of FIG. 1.

In this case, the adhesive layer 11 may attach the touch panel 310 to the front substrate 10 of the display panel 300.

Alternatively, the second substrate may be included in the 3D filter.

For example, as in FIG. 4, the 3D filter 400 disposed on the front surface of the display panel 300 may include a base substrate 401 and a lens unit 402 formed on the base substrate 401. . Here, the base substrate 401 may be the second substrate of FIG. 1.

The lens unit 402 may refract light generated by the display panel 300 to allow a viewer to three-dimensionally recognize an image implemented by the display panel 300. That is, it is possible to implement a stereoscopic image.

Alternatively, the 3D filter can be configured in a form different from that of FIG. 4.

For example, as in the case of FIG. 5, the 3D filter 500 disposed on the front surface of the display panel 300 may include the first filter substrate 12, the second filter substrate 501, and the first filter substrate 12. It is possible to include the seal portion 502 disposed between the second filter substrate 501 and the liquid crystal layer 503 sealed between the first filter substrate 12 and the second filter substrate 501. Here, the first filter substrate 501 may be the second substrate of FIG. 1.

Here, the liquid crystal layer 503 included in the 3D filter 500 includes a plurality of liquid crystal molecules, and the arrangement of the liquid crystal molecules may be changed according to a driving voltage applied from an electrode (not shown). Here, when the driving voltage applied to the liquid crystal molecules is adjusted, the 3D filter 500 may implement a stereoscopic image.

For example, as shown in FIG. 6, when images corresponding to a total of 120 frames (120 ms) are implemented per second, 60 right eye frames R and 60 left eye frames L may be alternately implemented. Alternatively, the right eye frame (R) and the left eye frame (L) may also be implemented in a method of implementing an image according to a total of 60 frames (60 ms method) in 1 second and a method of implementing an image according to a total of 240 frames (240 ms method) in 1 second. ) Can be placed alternately one by one.

For example, assuming that the operation of the 3D filter 500 is a normal white mode, the operation of the twisted nematic mode (TN mode) will be described below. In addition, it is assumed that the 3D glasses 710 include a left eye lens 711 having a phase delay value of λ / 4 and a right eye lens 712 having a phase delay value of −λ / 4.

As shown in FIG. 7, by supplying a first driving voltage to the electrode, the arrangement angle of the liquid crystal molecules 700 included in the liquid crystal layer 503 is adjusted so that the phase delay value of the liquid crystal layer 503 becomes λ / 4. can do. In this case, the light transmitted through the 3D filter 500 may be circularly polarized light having a phase delay of λ / 4.

Here, the viewer wearing the 3D glasses 710 may recognize the light transmitted through the 3D filter 500 through the left eye lens 711. On the other hand, in the case of FIG. 7, the light passing through the 3D filter 500 may not pass through the right eye lens 712 of the 3D glasses 710.

In addition, as shown in FIG. 8, the phase of the liquid crystal layer 503 is controlled by supplying a second driving voltage different from the first driving voltage to the electrode to adjust an arrangement angle of the liquid crystal molecules 700 included in the liquid crystal layer 503. The delay value can be 3λ / 4. In this case, the light transmitted through the 3D filter 500 may be circularly polarized light having a phase retardation value of 3λ / 4. The rotation direction of the circularly polarized light having the phase delay value of 3λ / 4 may be opposite to the rotational direction of the circularly polarized light having the phase delay value of λ / 4.

Here, the viewer wearing the 3D glasses 710 may recognize the light transmitted through the 3D filter 500 through the right eye lens 712. On the other hand, in the case of FIG. 8, the light passing through the 3D filter 500 may not pass through the left eye lens 711 of the 3D glasses 710.

As shown in FIGS. 7 and 8, the viewer recognizes the left eye image through the left eye lens 711 of the 3D glasses 710 and displays the right eye image through the right eye lens 712 to display on the display panel 300. It is possible to recognize the image in three dimensions.

Alternatively, as in the case of FIG. 9, in the right eye frame R, the liquid crystal molecules 700 of the liquid crystal layer 503 of the 3D filter 500 are linearly polarized light whose phase retardation value is 0 through the 3D filter 500. Can be arranged to be. On the other hand, in the left eye frame L, the liquid crystal molecules 700 of the liquid crystal layer 503 of the 3D filter 500 are arranged such that the light passing through the 3D filter 500 becomes linearly polarized light having a phase retardation value of λ / 2. Can be.

Even in this case, the viewer can view the stereoscopic image while wearing the 3D glasses 710 having a difference of approximately λ / 2 between the phase delay values of the left eye lens 711 and the right eye lens 712.

The second substrate may be a substrate included in the protective cover.

For example, as in the case of FIG. 10, the protective cover 2000 disposed on the front surface of the display panel 300 may include a substrate 2010 and a protective film 2020 disposed on the substrate 2010. . Here, the substrate 2010 may be the second substrate of FIG. 1.

In this structure, the protective cover 2000 may protect the display panel 300 from impact and damage.

Meanwhile, in FIGS. 1 to 10, the adhesive layer 11 only illustrates a case in which the adhesive layer 11 is in contact with the first substrate 10 and the second substrate 12, respectively. Alternatively, the adhesive layer 11 may be the first substrate. It is also possible to make contact with either of the 10 or the second substrate 12. In addition, another layer may be formed between the adhesive layer 11 and the first substrate 10, or another layer may be formed between the adhesive layer 11 and the second substrate 12.

11 to 20 are views for explaining the adhesive layer in more detail. Hereinafter, the description of the parts described in detail above will be omitted. For example, below, the first substrate may be a substrate included in the display panel, and the second substrate may be a substrate included in a touch panel, a 3D filter, a protective cover, or the like.

Referring to FIG. 11, the adhesive layer 11 disposed between the first panel 300 and the second panel 310 may include a first portion 1000 and a second portion 1010 having different fluidity. . For example, the adhesive layer 11 may include a first portion 1000 having a first fluidity and a second portion 1010 having a second fluidity different from the first fluidity.

If the first flowability of the first portion 1000 is greater than the second flowability of the second portion 1010, the first portion 1000 may be any of the first panel 300 and the second panel 310. It is possible to contact with one. For example, as in the case of FIG. 11, the first portion 1000 having relatively large fluidity may be able to contact the second substrate 12. Here, the positions of the first part 1000 and the second part 1010 may be changed.

In this case, the second portion 1010 may be disposed between the first portion 1000 and the first substrate 10 or may be disposed between the first portion 1000 and the second substrate 12. .

Alternatively, a liquid layer may be formed between the adhesive layer 11 and the first substrate 10 or between the adhesive layer 11 and the second substrate 12.

For example, as in the case of FIG. 12, the liquid layer 1100 may be formed between the adhesive layer 11 and the second substrate 12. Preferably, the liquid layer 1100 may be formed between the first portion 1000 and the second substrate 12 having relatively large fluidity.

Alternatively, the liquid layer 1100 may be formed between the first substrate 10 and the adhesive layer 11.

Looking at the bonding method of the first panel 300 and the second panel 310 is as follows.

Referring to FIG. 13A, the adhesive layer 11 may be manufactured in the form of a green sheet. For example, the adhesive sheet 1250 may include an adhesive layer 11, a first protective layer 1200, and a second protective layer 1210.

The first protective layer 1200 may be disposed on one surface of the adhesive layer 11, and the second protective layer 1210 may be disposed on the other surface of the adhesive layer 11. The first protective layer 1200 and the second protective layer 1210 may protect the adhesive layer 11 from damage. Here, although the case in which the first protective layer 1200 and the second protective layer 1210 are disposed on one surface and the other surface of the adhesive layer 11 is illustrated, among the first protective layer 1200 and the second protective layer 1210. At least one may be omitted.

Next, referring to FIG. 13B, the apparatus for manufacturing a display apparatus according to the present invention includes a roller unit for bonding the first panel 300 and the second panel 310 to each other.

The roller part may include a first roller part 1220, a second roller part 1230, and a third roller part 1240.

The second roller part 1230 may separate the first protective layer 1200 from the adhesive sheet 1250.

The first roller part 1220 may apply the pressure to the adhesive sheet 1250 to attach the adhesive layer 11 to the first panel 300, for example, the first substrate 10.

The third roller part 1240 may separate the second protective layer 1210 from the adhesive sheet 1250.

In the roller unit described above, at least one of the second roller unit 1230 or the third roller unit 1240 may be omitted. For example, when the first protective layer 1200 is omitted from the adhesive sheet 1250, the second roller part 1230 may be omitted from the roller part.

The adhesive layer 11 may be formed on the first panel 300 by the first, second, and third roller parts 1220, 1230, and 1240.

Thereafter, as shown in FIG. 14A, the liquid material 1300 may be applied to the surface of the adhesive layer 11. Herein, the liquid material 1300 may be in a liquid state. For example, it may be water (H ₂ O) of the liquid material (1300). In order to improve the adhesion between the adhesive layer 11 and the first substrate 10 or the adhesive layer 11 and the second substrate 12, the liquid material 1300 may preferably include an acrylic oligomer polymer material.

Although the case where the adhesive layer 11 is formed on the 1st board | substrate 10 and the liquid material 1300 is apply | coated to the adhesive layer 11 is demonstrated as an example here, the adhesive layer 11 is attached to the 2nd board | substrate 12 here. It may also be possible to form a liquid material 1300 in the adhesive layer (11).

In addition, the liquid material 1300 may be applied to the adhesive layer 11, but the liquid material 1300 may be applied to the second substrate 12, and the second substrate may be coated with the liquid material 1300 ( It may also be possible to attach 12 to the adhesive layer 11.

Thereafter, as illustrated in FIG. 14B, the second substrate 12 may be attached to the adhesive layer 11 to which the liquid material 1300 is applied. In other words, the first substrate 10 and the second substrate 12 may be bonded to each other such that the adhesive layer 11 is positioned between the first substrate 10 and the second substrate 12.

Thereafter, as shown in FIG. 14C, after the first substrate 10 and the second substrate 12 are bonded to each other, the first substrate 10 and the second substrate 12 may be compressed to closely contact each other. . For example, after arranging the pressing roller 1310 on the surface of the second substrate 12, applying pressure while moving the pressing roller 1310 on the second substrate 12, the first substrate 10 and the second substrate. The substrate 12 may be strongly bonded.

In this process, the liquid material 1300 applied between the second substrate 12 and the adhesive layer 11 is mostly disposed outwardly by the pressure applied by the pressing roller 1310, and a part of the second substrate 12 is disposed. And may remain between the adhesive layer 11. In this case, the liquid material 1300 remaining between the second substrate 12 and the adhesive layer 11 may be absorbed by the adhesive layer 11 to form a first portion 1000 having a relatively high fluidity. Accordingly, the first portion 1000 and the second portion 1010 having different fluidity may be formed in the adhesive layer 11.

If the liquid material 1300 remaining between the second substrate 12 and the adhesive layer 11 remains unabsorbed by the adhesive layer 11, the second substrate 12 and the adhesive layer 11 may be separated from each other. The liquid layer can be formed in.

As described above, when the first substrate 10 and the second substrate 12 are bonded to each other using the liquid material 1300, the liquid material 1300 may have the adhesive layer 11 as in the case of FIG. 15. It can penetrate into the voids 1400 formed in the. For example, the liquid material 1300 may be filled in the void 1400 formed in the adhesive layer 11 between the second substrate 12 and the adhesive layer 11.

Accordingly, the adhesion between the second substrate 12 and the adhesive layer 11 is further improved, and as a result, the adhesion between the first substrate 10 and the second substrate 12 may be improved.

16, when the liquid material 1300 remaining between the second substrate 12 and the adhesive layer 11 remains unabsorbed by the adhesive layer 11, the second substrate 12 may be used. Liquid layer 1100 is formed between the second substrate 12 and the adhesive layer 11 while the liquid material 1300 is filled in the void 1400 formed in the adhesive layer 11 between the adhesive layer 11 and the adhesive layer 11. It may be possible to be.

Even in this case, adhesion between the first substrate 10 and the second substrate 12 may be improved by the viscosity of the liquid material 1300.

Meanwhile, as in the case of FIG. 17, a plurality of voids 1400 may be formed in the adhesive layer 11 regardless of the position. For example, it may be possible that a plurality of voids 1400 are formed in the first portion 1000 and the second portion 1010 of the adhesive layer 11, respectively. In this case, at least one of the pores 1400 formed in the first part 1000 of the adhesive layer 11 is filled with a liquid material, whereas the pores 1400 formed in the second part 1010 have a liquid material ( 1300 may not be filled.

Meanwhile, as in the case of FIG. 18, it may be possible to use a spray method when applying the liquid material 1300 to the adhesive layer 11. For example, the liquid material 1300 may be applied to the surface of the adhesive layer 11 using the spray nozzle 1700.

In this case, it may be possible to apply the liquid material 1300 more evenly.

Alternatively, as in the case of FIG. 19, the liquid material 1300 may be applied to the surface of the adhesive layer 11 at a plurality of positions in a dot method. For example, a predetermined amount of the liquid material 1300 may be applied to a predetermined specific position on the adhesive layer 11. In this case, the liquid material 1300 may be evenly spread in the pressing process by the pressing roller 1310.

If the first substrate 10 and the second substrate 12 are bonded to each other without using the liquid material 1300 unlike the present invention, as shown in FIG. 20, the adhesive layer 11 and the second substrate are bonded to each other. Defects, such as the bubble 1900, may be formed between the 12.

In this case, even when the pressing process using the pressing roller 1310 is performed, defects such as the bubbles 1900 may not be removed. Therefore, in this case, the first substrate 10 and the second substrate 12 should be bonded together in a vacuum state to remove defects such as the coupon 1900.

On the other hand, in the present invention, since the liquid material is used in the process of bonding the first substrate 10 and the second substrate 12, not only the occurrence of defects such as the bubble 1900 can be suppressed, but also the first It may be possible to improve the bonding force between the substrate 10 and the second substrate 12.

In addition, even when the first substrate 10 and the second substrate 12 are bonded to each other at normal pressure instead of vacuum, occurrence of defects such as the coupon 1900 can be suppressed.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Therefore, the exemplary embodiments described above are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the appended claims rather than the foregoing detailed description, and the meaning and scope of the claims are as follows. And all changes or modifications derived from the equivalent concept should be interpreted as being included in the scope of the present invention.
