1 to 7 are views for explaining a configuration of a multi-display device according to the present invention.

Referring to FIG. 1, the multi-display device 10 according to the present invention may include a plurality of plasma display panels 100, 110, 120, and 130 disposed adjacent to each other.

The first 1-1 driving part 101 and the 1-2 driving part 102 can supply driving signals to the first panel 100 of the plurality of plasma display panels 100-130. Here, the 1-1 driving unit 101 and the 1-2 driving unit 102 may be merged into one integrated driving unit.

In addition, the second panel driving unit 111 and the second driving unit 112 can supply driving signals to the second panel 110.

As described above, it is possible to set the driving signals to be supplied to the respective PDPs 100, 110, 120, and 130, respectively.

Each of the driving units may be a driving board.

2, the first frame 200A is disposed on the rear surface of the first panel 100, that is, the rear surface of the rear substrate of the first panel 100, A second frame 200B is disposed on the rear surface of the second panel 110. A third frame 200C is disposed on the rear surface of the third panel 120. On the rear surface of the fourth panel 130, (200D) can be disposed.

The first, second, third, and fourth frames 200A to 200D disposed on the back surfaces of the first, second, third, and fourth panels 100 to 130 may include a metal material, A heat sink, a heat radiating frame, a chassis, or the like.

A first filter 210a is disposed on the front surface of the first panel 100, that is, a front surface of the front panel of the first panel 100, and a second filter 210B is disposed on the front surface of the second panel 110 A third filter 210C is disposed on the front surface of the third panel 120 and a fourth filter 210D is disposed on the front surface of the fourth panel 130. [

In addition, the first, second, third, and fourth filters 210A to 210D may include electromagnetic wave shielding layers (not shown).

Driving boards 101 to 132 for supplying driving signals to the first, second, third and fourth panels 100 to 130 may be disposed on the back surfaces of the first, second, third and fourth frames 200A to 200D .

In addition, as in the case of FIG. 11, a Seam Area (SA) 140, 150 may be formed between adjacent two plasma display panels. The shim regions 140 and 150 may be referred to as a region between adjacent two plasma display panels.

Since the multi-display device 10 implements an image by disposing the individual plasma display panels 100 to 130 adjacent to each other, the core regions 140 and 150 are formed between the adjacent two plasma display panels 100 to 130 .

The plasma display panels 100 to 130 may implement an image using a frame including a plurality of subfields.

3, the plasma display panels 100 to 130 include a plurality of first electrodes 202 (Y) and a plurality of second electrodes 213 (X) intersecting with the plurality of first electrodes 202 (211).

Here, the first electrodes 202 and 203 may include the scan electrodes 202 and Y and the sustain electrodes 203 and Z, and the second electrode 211 may be referred to as an address electrode.

The discharge currents of the scan electrodes 202 and the sustain electrodes 203 and the sustain electrodes 203 are applied to the front substrate 201 on which the scan electrodes 202 and the sustain electrodes 203 and the sustain electrodes Z are formed. ) And the sustain electrodes 203, Z may be disposed on the lower dielectric layer 204. In this case,

The front substrate 201 on which the upper dielectric layer 204 is formed may be provided with a protective layer 205 for facilitating discharge conditions. The protective layer 205 may include a material having a high secondary electron emission coefficient, for example, a magnesium oxide (MgO) material.

Address electrodes 213 and X are formed on the rear substrate 211 and address electrodes 213 and X are formed on the rear substrate 211 on which the address electrodes 213 and X are formed. The lower dielectric layer 215 may be formed.

Barrier ribs 212 such as a stripe type, a well type, a delta type, and a honeycomb type for partitioning a discharge space, that is, a discharge cell, are formed on an upper portion of the lower dielectric layer 215 . Accordingly, a first discharge cell that emits red (R) light, a second discharge cell that emits blue (B) light, and a second discharge cell that emits green (Green) light are provided between the front substrate 201 and the rear substrate 211, : G) a third discharge cell that emits light, or the like.

On the other hand, in the discharge cell, the address electrode 213 may cross the scan electrode 202 and the sustain electrode 203. That is, the discharge cells are formed at the intersections of the address electrodes 213 with the scan electrodes 202 and the sustain electrodes 203.

A predetermined discharge gas may be filled in the discharge cells partitioned by the barrier ribs 212.

In addition, in the discharge cells partitioned by the barrier ribs 212, a phosphor layer 214 that emits visible light for image display upon address discharge may be formed. For example, a first phosphor layer for generating red light, a second phosphor layer for generating blue light, and a third phosphor layer for generating green light may be formed.

The width and thickness of the address electrode 213 formed on the rear substrate 211 may be substantially constant in width or thickness but may be different from the width or thickness of the inside of the discharge cell outside the discharge cell . For example, the width or thickness inside the discharge cell may be wider or thicker than that outside the discharge cell.

When a predetermined signal is supplied to at least one of the scan electrode 202, the sustain electrode 203, and the address electrode 213, a discharge may occur in the discharge cell. When a discharge is generated in the discharge cell, ultraviolet rays can be generated by the discharge gas filled in the discharge cell, and such ultraviolet rays can be irradiated to the phosphor particles of the phosphor layer 214. Then, the phosphor particles irradiated with the ultraviolet rays emit visible light, so that a predetermined image can be displayed on the screen of the plasma display panel 100.

An image frame for implementing the gradation of the image in the plasma display panels 100 to 130 will be described below. Here, the image frame is different from the first, second, third, and fourth frames 200A to 200D, which are disposed on the back surface of the plasma display panels 100 to 130 of FIG.

Referring to FIG. 4, a frame for implementing a gray level of an image may include a plurality of subfields (SF1 to SF8).

In addition, a plurality of subfields are divided into an address period for selecting a discharge cell in which a discharge will not occur or a discharge period for selecting a discharge cell in which a discharge occurs, and a sustain period for implementing a gray level according to the number of discharges Period).

For example, when an image is to be displayed at 256 gray levels, one frame is divided into eight subfields (SF1 to SF8) as shown in FIG. 4, and eight subfields (SF1 to SF8) And a sustain period.

Alternatively, at least one of the plurality of subfields of the frame may further include a reset period for initialization.

In addition, at least one of the plurality of subfields of the frame may not include a sustain period.

On the other hand, the number of the sustain signals supplied in the sustain period may be adjusted to set the weight of the corresponding subfield. That is, a predetermined weight can be given to each subfield using the sustain period. For example, the weight of the first subfield is set to 2 ⁰ , and the weight of the second subfield is set to 2 ¹ , so that the weight of each subfield is 2 ⁿ (n = 0, 1, 2, 3, 4, 5, 6, 7). By adjusting the number of the sustain signals supplied in the sustain period of each sub-field in accordance with the weight value in each sub-field, it is possible to implement various image gradations.

In FIG. 4, only one video frame is composed of eight subfields. However, the number of subfields forming one video frame can be changed variously. For example, one video frame may be composed of 12 sub-fields from the first sub-field to the 12th sub-field, or one video frame may be composed of 10 sub-fields.

In FIG. 4, the subfields are arranged according to the increasing order of the weights in one image frame. Alternatively, in one image frame, the subfields may be arranged in decreasing order of weights, The subfields may be arranged regardless of the subfields.

Driving waveforms for driving the plasma display panels 100 to 130 will be described below.

5, in a reset period (RP) for initializing at least one sub-field among a plurality of sub-fields of a frame, a reset signal RS is applied to the scan electrode Y Can supply. Here, the reset signal RS may include a rising ramp signal Ramp-Up RU whose voltage gradually increases and a falling ramp signal Ramp-Down RD whose voltage gradually falls.

For example, the rising ramp signal RU may be supplied to the scan electrode in the set-up period SU of the reset period, and the falling ramp signal RD may be supplied to the scan electrode during the set-down period SD after the set- .

When a rising ramp signal is supplied to the scan electrode, a weak dark discharge (i.e., setup discharge) occurs in the discharge cell due to the rising ramp signal. By this set-up discharge, the distribution of wall charges (Wall Charge) in the discharge cells can be made uniform.

When a falling ramp signal is supplied to the scan electrode after the rising ramp signal is supplied, a weak erase discharge (setdown discharge) occurs in the discharge cell. Due to the set-down discharge, wall charges can be uniformly left in the discharge cells to such an extent that address discharge can occur stably.

In the address period AP after the reset period, a scan reference signal Ybias having a voltage higher than the lowest voltage of the falling ramp signal may be supplied to the scan electrode.

In the address period, the scan signal Sc falling from the voltage of the scan reference signal Ybias may be supplied to the scan electrode.

The pulse width of the scan signal supplied to the scan electrodes in the address period of at least one subfield may be different from the pulse width of the scan signals of the other subfields. For example, the width of the scan signal in the subfields positioned later in time may be smaller than the width of the scan signal in the subfields positioned in front. In addition, the decrease in the scan signal width according to the arrangement order of the subfields can be made progressively, such as 2.6 mu s, 2.3 mu s, 2.1 mu s, 1.9 mu s, or the like, or 2.6 mu s, 2.3 mu s, 1.9 占 퐏, 1.9 占 퐏, and so on.

As described above, when the scan signal is supplied to the scan electrode, the data signal Dt may be supplied to the address electrode X corresponding to the scan signal.

When such a scan signal and a data signal are supplied, a wall voltage due to wall charges generated in the reset period and a voltage difference between the scan signal and the data signal are added, and an address discharge may be generated in the discharge cell to which the data signal is supplied .

In addition, in the address period in which the address discharge occurs, the sustain reference signal Zbias may be supplied to the sustain electrode in order to effectively generate the address discharge between the scan electrode and the address electrode.

In the sustain period SP after the address period, the sustain signal SUS may be supplied to at least one of the scan electrode and the sustain electrode. For example, the sustain signal may be alternately supplied to the scan electrode and the sustain electrode.

When the sustain signal is supplied, the wall voltage in the discharge cell and the sustain voltage (Vs) of the sustain signal are added to the discharge cells selected by the address discharge. When the sustain signal is supplied, a sustain discharge is generated between the scan electrode and the sustain electrode Discharge may occur.

The first, second, third and fourth filters 210A to 210D disposed on the front of the plasma display panels 100 to 130 may include an electromagnetic wave shielding layer. The details are as follows.

Referring to FIG. 6, the filters 210A to 210D may include a substrate 211, an electromagnetic wave shielding layer 214, and another functional layer 215. Further, although not shown, an adhesive layer may be disposed between the substrate 211 and the electromagnetic wave shielding layer 214 and / or between the substrate 211 and the functional layer 215.

Here, the electromagnetic wave shielding layer 214 may include a plurality of transparent electrode layers 213 and a plurality of metal electrode layers 212. In addition, the plurality of transparent electrode layers 213 and the plurality of metal electrode layers 212 may be alternately arranged. That is, the transparent electrode layer 213 and the metal electrode layer 212 can be alternately stacked.

The electromagnetic wave shielding layer 214 having such a structure can be referred to as a sputter-type electromagnetic wave shielding layer. The stuffer type may mean a structure in which two or more different conductive layers are stacked.

The transparent electrode layer 213 is made of a material that is substantially transparent and electrically conductive such as indium-tin oxide (ITO), and the metal electrode layer 212 is formed of a material having high electrical conductivity Materials may be included.

As described above, when the substantially transparent transparent electrode layer 213 and the metal electrode layer 212 containing silver (Ag) material having excellent electrical conductivity are stacked in order, the light transmittance can be sufficiently secured and the electrical conductivity can be sufficiently increased .

Accordingly, it is possible to sufficiently absorb the electric charges generating the electromagnetic wave, thereby reducing the occurrence of electromagnetic interference (EMI), and it is possible to prevent the luminance of the implemented image from becoming excessively low.

The thickness t2 of the transparent layer 213 can be set to about 300 angstroms or more and 800 angstroms or less in order to maintain the light transmittance at a sufficiently high level and the thickness t1 of the metal electrode layer 212 is set to about 100 angstroms or more and 200 angstroms or less .

In addition, the functional layer 215 may be a near infrared ray shielding layer capable of shielding near infrared rays by absorbing or reflecting near infrared rays (NIR).

Or the functional layer 215 may include a color layer, an anti-glare layer, or an anti-reflection layer.

7 (a), the filter 210 may include an electromagnetic wave shielding layer 214 including a substrate 211 and a metal layer 216 in the form of a mesh.

Here, the metal layer 216 in the form of a mesh is an electromagnetic wave shielding layer.

The mesh-type electromagnetic wave shielding layer 214 can sufficiently absorb the electric charges that generate electromagnetic waves, thereby reducing the occurrence of Electro Magnetic Interference (EMI).

The color of the mesh-shaped metal layer 216 may be made darker than the color of the substrate 211 in order to prevent reflection of light by the mesh-shaped metal layer 216. For example, although not shown, reflection of light by the mesh-shaped metal layer 216 can be prevented by applying a material having a substantially black color such as a carbon material on the metal layer 216 . Alternatively, a material having a substantially black color may be formed or coated on the lower portion of the mesh-shaped metal layer 216 to absorb the interference light emitted from the plasma display panel.

As shown in Fig. 7B, the line width S1 of the metal electrode layer 216 in a mesh form can be set to 10 mu m (micrometer) or more and 30 mu m (micrometer) or less. The shortest distance S2 between the lines of the metal electrode layers 216 in a mesh form can be set to 200 mu m (micrometer) or more and 300 mu m (micrometer) or less.

8 to 19 are views for explaining the structure of a multi-display device according to the present invention in detail. Hereinafter, the description of the parts described in detail above will be omitted. For example, in the following description, only a plasma display panel is applied. However, any display panel may be used as long as a frame is disposed on the rear surface of the panel in addition to the plasma display panel.

3, the plasma display panels 100 to 130 each include a front substrate 201, a rear substrate 211 disposed to face the front substrate 201, a front substrate 201, And a seal layer (400) disposed between the substrate and the rear substrate. Here, the seal layer 400 may serve to bond the front substrate 201 and the rear substrate 211 together.

An electromagnetic wave shielding layer 214 may be disposed on the front surface of the plasma display panel 100 to 130, that is, on the front surface of the front substrate 201. In addition, as described above, the electromagnetic wave shielding layer 214 may include a metal layer for shielding electromagnetic waves. Although FIG. 8 discloses a case where only the electromagnetic wave shielding layer 214 is disposed on the front surface of the front substrate 201, the above-described filter can be disposed.

The frame 200 may be disposed on the rear surface of the plasma display panels 100 to 130, that is, on the rear surface of the rear substrate 211. In addition, an electromagnetic wave shielding layer 214 may be disposed on a front surface of the plasma display panels 100 to 130.

The electromagnetic wave shielding layer 214 may extend to the frame 200. That is, a part of the electromagnetic wave shielding layer 214 can contact the frame 200. Accordingly, the electromagnetic shielding layer 214 can be moved to the frame 200 electrically connected to the frame 200, and the electric charges collected by the electromagnetic shielding layer 214 when the display panel is driven are grounded (GND) Electromagnetic waves can be shielded.

The portion extending from the electromagnetic wave shielding layer 214 to the frame 200 contacts not only the frame 200 but also the side of the portion W1 where the image is not displayed by being in close contact with the side surface of the plasma display panel 20. [ The size can be reduced. That is, the size of the bezel area where the image is not displayed can be reduced.

9, when the plasma display panels 100 to 130 are applied, a buffer layer 800 may be disposed between a side surface of the seal layer 400 and an extended portion of the electromagnetic wave shielding layer 214 . Alternatively, the buffer layer 800 may be disposed between the side surface of the front substrate 201 and the extended portion of the electromagnetic wave shielding layer 214. Alternatively, the buffer layer 800 may be disposed between the side surface of the rear substrate 211 and the extended portion of the electromagnetic wave shielding layer 214.

The buffer layer 800 may include a resin material and may be attached to the side surfaces of the plasma display panels 100 to 130 in the form of a sheet.

The buffer layer 800 can prevent the electromagnetic wave shielding layer 214 from being disconnected from the frame 200 by fixing the extended portion of the electromagnetic wave shielding layer 214.

In addition, the buffer layer 800 may have adhesiveness. In this case, the extended portion of the electromagnetic wave shielding layer 214 is further adhered to the side surfaces of the plasma display panels 100 to 130, thereby further reducing the size of the bezel area where no image is displayed. In this case, the buffer layer 800 may be referred to as an adhesive layer.

Optionally, the buffer layer 800 may also be omitted.

A manufacturing method of a multi-display device according to the present invention having such a structure will be described below.

Thereafter, an exhaust tip (not shown) is connected to an exhaust hole (not shown), and an exhaust pump (not shown) can be connected to the exhaust tip.

In addition, an impurity gas remaining in a discharge space between the front substrate 201 and the rear substrate 211 can be discharged to the outside by using an exhaust pump, and argon (Ar), neon (Ne), xenon (Xe) Or the like can be injected into the discharge space.

In this way, the discharge space between the front substrate 201 and the rear substrate 211 can be sealed.

11A, a part of the front substrate 201 and the rear substrate 211 is cut along the first cutting line CL1 in a state where the front substrate 201 and the rear substrate 211 are attached to each other, . Here, grinding can be performed together.

11 (b), it is possible to prevent at least one of the front substrate 201 and the rear substrate 211 from being excessively protruded. Accordingly, the size of the portion where the image is not displayed Can be reduced.

Meanwhile, it is also possible to cut the seal layer 400 together in the process of cutting a part of the front substrate 201 and the rear substrate 211 as shown in FIG. 11 (a). As described above, if the seal layer 400 is cut, the size of the portion where the image is not displayed can be further reduced.

11 (c), the electromagnetic wave shielding layer 214 may be disposed on the front surface of the front substrate 201, and the frame 200 may be disposed on the rear surface of the rear substrate 211. Referring to FIG.

Thereafter, a part of the electromagnetic wave shielding layer 214 may be connected to the frame 200.

As described above, it is possible to ground the electromagnetic wave shielding layer 214 by a simple method of connecting the elongated portion of the electromagnetic wave shielding layer 214 to the frame 200.

11, when the front substrate 201 and the rear substrate 211 are partially cut, the electromagnetic wave shielding layer 214 and the plasma display panel (not shown) disposed on the front surfaces of the plasma display panels 100 to 130 The shortest distance between the frames 200 disposed on the back surface of the display devices 100 to 130 can be shortened. The electromagnetic wave shielding layer 214 disposed on the front surface of the plasma display panels 100 to 130 can be more easily connected to the frame 200 disposed on the back surface of the plasma display panels 100 to 130 .

Meanwhile, in order to form an extended portion of the electromagnetic wave shielding layer 214 on the filter 210, a half cutting method can be applied. The following will be described with reference to FIG.

12A, the filter 210 includes a first base layer 500, an electromagnetic wave shielding layer 214 disposed on the first base layer 500, an adhesive layer 214 disposed on the electromagnetic wave shielding layer 214, A color / near-infrared ray layer 520, a second base layer 530, an anti-reflection layer 540, and a protection layer 540 (PR, Protection Layer) can do.

Here, the first base layer 500 may be cut along the second cutting line CL2 so that the electromagnetic wave shielding layer 214 protrudes by a predetermined length as shown in FIG. 11 (b). As described above, the method of cutting the first base layer 500 while leaving the electromagnetic wave shielding layer 214 as it is can be referred to as a half cutting method.

It is possible to connect the electromagnetic wave shielding layer 214 protruded by half cutting to the frame 200 as shown in FIG. 12 (b).

On the other hand, portions extending to the frame of the electromagnetic wave shielding layer disposed in front of a plurality of adjacent display panels can be staggered. 13, the protrusion 1300 of the first electromagnetic wave shielding layer 214A disposed on the front surface of the first panel 100 of the multi-display device and the protrusion 1300 of the second electromagnetic wave The protrusions 1310 of the shielding layer 214B can be staggered from each other. The protrusion 1300 of the first electromagnetic wave shielding layer 214A extends to the first frame 200A disposed on the rear surface of the first panel 100 and is connected to the first frame 200A, The protrusion 1310 of the layer 214B may extend to the second frame 200B disposed on the rear surface of the second panel 110 and may be connected to the second frame 200B. That is, the protrusions 1300 and 1310 of the first and second electromagnetic wave shielding layers 214A and 214B can be said to extend to the first and second frames 200A and 200B.

It is preferable that the protrusion 1300 of the first electromagnetic wave shielding layer 214A and the protrusion 1300 of the second electromagnetic wave shielding layer 214B are formed on the first panel 100 and the second panel 110, The protrusions 1310 of the recesses 214B may be spaced a predetermined distance D1 in a second direction that intersects the first direction.

When the protrusion 1300 of the first electromagnetic wave shielding layer 214A is disposed on the side surface of the first panel 100 and the protrusion 1310 of the second electromagnetic wave shielding layer 214B is disposed on the side surface of the second panel 110 The protrusions 1300 and 1310 of the first and second electromagnetic wave shielding layers 214A and 214B may be disposed between the first panel 100 and the second panel 110 as in the case of FIG.

The protrusion 1300 of the first electromagnetic wave shielding layer 214A is disposed on the side surface of the first panel 100 and the protrusion 1310 of the second electromagnetic wave shielding layer 214B is disposed on the side surface of the second panel 110. [ The protruding portion 1300 of the first electromagnetic wave shielding layer 214A and the protruding portion 1310 of the second electromagnetic wave shielding layer 214B may not be in contact with each other. Accordingly, the size of the core region SA between the first panel 100 and the second panel 110 can be reduced. This will be described in more detail with reference to FIG.

15, in a boundary portion between two plasma display panels, for example, a boundary portion between the first panel 100 and the second panel 110, that is, in the core region SA, the first electromagnetic wave shielding layer 214A has a first And may extend to the frame 200A. That is, the protrusion 1300 of the first electromagnetic wave shielding layer 214A can contact the first frame 200A. The second electromagnetic wave shielding layer 214B may extend to the second frame 200B in the core region SA of the first panel 100 and the second panel 110. [ That is, the protrusion 1310 of the second electromagnetic wave shielding layer 214B can contact the second frame 200B.

In addition, since the protrusion 1300 of the first electromagnetic wave shielding layer 214A and the protrusion 1310 of the second electromagnetic wave shielding layer 214B are spaced apart from each other in the second direction, the first panel 100 and the second panel 110 The protrusion 1300 of the first electromagnetic wave shielding layer 214A and the protrusion 1310 of the second electromagnetic wave shielding layer 214B are seen to overlap with each other, The first panel 100 and the second panel 110 can be more closely contacted. Accordingly, the size of the core region SA between the first panel 100 and the second panel 110 can be reduced.

11, a part of the first panel 100 and the second panel 110 are cut and grinded in the core region SA of the first panel 100 and the second panel 110, . The first electromagnetic wave shielding layer 214A is extended to the first frame 200A in the core region SA of the first panel 100 and the second panel 110 and the second electromagnetic wave shielding layer 214B is extended to the first frame 200A, It may be easier to extend the second frame 200B to the second frame 200B.

In addition, the size of the shim area SA in which no image is displayed can be reduced. Accordingly, a more natural image can be realized in the multi-display device according to the present invention.

Alternatively, the electromagnetic wave shielding layer 214 may extend only to the side of the display panel without extending to the frame 200.

16, the electromagnetic wave shielding layer 214 may include a first portion 600 disposed on the front surface of the display panel and a second portion 610 disposed on the side surface of the display panel . In addition, the second portion 610 may include a portion disposed on a side surface of the front substrate 201. Alternatively, the second portion 610 may include a portion disposed on the side surface of the seal layer 400. 8, the second portion 610 of the electromagnetic wave shielding layer 214 may be seen to extend to the frame 200. In addition, the protrusions 1300 and 1310 shown in FIG. 13 can be regarded as the second portion 610.

A conductive portion 700 may be formed between the second portion 610 of the electromagnetic wave shielding layer 214 and the frame 200. The conductive part 700 can connect the frame 200 with the second part 610 of the electromagnetic wave shielding layer 214 and thus the electromagnetic wave shielding layer 214 can be grounded.

The conductive portion 700 may be a conductive tape.

16, when the second portion 610 of the electromagnetic wave shielding layer 214 is connected to the frame 200 using the conductive portion 700, even if the length L1 of the second portion 610 is short It is acceptable. The length L1 of the second portion 610 of the electromagnetic wave shielding layer 214 may be shorter than the length L2 of the conductive portion 700. [ This is because the process of attaching the conductive portion 700 may be easier than the process of forming the second portion 610 of the electromagnetic wave shielding layer 214. [

Even when the second portion 610 of the electromagnetic wave shielding layer 214 and the frame 200 are connected to each other using the conductive portion 700, the conductive portions 700 disposed on the sides of two adjacent plasma display panels are staggered It is possible to deploy.

For example, as in the case of Fig. 17, in a boundary portion between two plasma display panels, for example, a boundary portion between the first panel 100 and the second panel 110, that is, the core region SA, The shielding layers 214A and 214B include first portions 600A and 600B disposed on the front surfaces of the first and second panels 100 and 110 and second portions 600A and 600B disposed on the side surfaces of the first and second panels 100 and 110. [ Gt; 610A, < / RTI > 610B. In addition, the second portions 610A and 610B may include portions disposed on the side surfaces of the front substrates 201A and 201B. Alternatively, the second portions 610A and 610B may include portions disposed on the side surfaces of the seal layers 400A and 400B.

The first and second conductive parts 700A and 700B are formed between the second portions 610A and 610B of the first and second electromagnetic wave shielding layers 214A and 214B and the first and second frames 200A and 200B . The first and second conductive parts 700A and 700B can connect the first and second frames 200A and 200B with the second parts 610A and 610B of the first and second electromagnetic wave shielding layers 214A and 214B, The first and second electromagnetic wave shielding layers 214A and 214B may be grounded.

The second portion 600A of the first electromagnetic wave shielding layer 214A and the second portion 600B of the second electromagnetic wave shielding layer 214B are disposed between the first panel 100 and the second panel 110 . In addition, the first conductive portion 700A and the second conductive portion 700B may be disposed between the first panel 100 and the second panel 110.

In addition, the first conductive portion 700A and the second conductive portion 700B may be spaced apart from each other by a predetermined distance D2 in the second direction. The first conductive portion 700A and the second conductive portion 700B are overlapped when the core region SA is viewed from the sides of the first panel 100 and the second panel 110, In addition, the first panel 100 and the second panel 110 can be more closely contacted. Accordingly, the size of the core region SA between the first panel 100 and the second panel 110 can be reduced.

Alternatively, it is possible that the electromagnetic wave shielding layer 214 does not include a portion disposed on the side surface of the plasma display panel. This will be described in detail as follows.

18, one side of the conductive part 700 disposed on the side of the plasma display panel is connected to the side of the electromagnetic wave shielding layer 214, and the other side of the conductive part 700 is connected to the frame 200 .

Preferably, the conductive portion 700 may be connected to the electromagnetic wave shielding layer 214 on the front surface of the plasma display panel.

In this structure, the process for grounding the electromagnetic wave shielding layer 214 may be easier.

In this way, even when the electromagnetic shielding layer 214 and the conductive layer 700 are connected to each other on the front surface of the plasma display panel, the conductive parts 700 disposed on the sides of two adjacent plasma display panels can be staggered.

For example, as in the case of FIG. 19, in a boundary portion between two plasma display panels, for example, a boundary portion between the first panel 100 and the second panel 110, that is, the core region SA, One side of the first conductive part 700A is connected to the first electromagnetic wave shielding layer 214A and the other side of the first conductive part 700A is connected to the first frame 200A . One side of the second conductive portion 700B is connected to the second electromagnetic wave shielding layer 214B on the front surface of the second panel 110 and the other side of the second conductive portion 700B is connected to the rear surface of the second panel 110 And may be connected to the second frame 200B to be disposed. Accordingly, the first and second electromagnetic wave shielding layers 214A and 214B can be grounded.

In addition, the first conductive portion 700A and the second conductive portion 700B may be spaced a predetermined distance D3 in the second direction. The first conductive portion 700A and the second conductive portion 700B are overlapped when the core region SA is viewed from the sides of the first panel 100 and the second panel 110, In addition, the first panel 100 and the second panel 110 can be more closely contacted. Accordingly, the size of the core region SA between the first panel 100 and the second panel 110 can be reduced.

20 to 24 are views for explaining another structure of the multi-display device according to the present invention. Hereinafter, the description of the parts described in detail above will be omitted.

However, As shown in FIG.
