The blocking unit 1500 blocks the dummy area of the screen area (active area, active area) where the image of the display panel 100 is displayed, thereby making the image displayed in the screen area more prominent .

Such a blocking portion 1500 can have a lower brightness than the surrounding. For example, the brightness of the blocking portion 1500 may be lower than the brightness of the display panel 100. [ For this purpose, the blocking part 1500 can have a substantially black color. For example, the blocking portion 1500 may be a substantially black tape, and may be formed by attaching a black tape to the front surface of the front substrate 101.

The blocking portion 1500 may be referred to as a black layer.

[ That is, almost all the portions of the blocking portion 1500 can be observed.

On the other hand, since the bracket 140 does not display an image, it may be preferable that the bracket 140 is disposed in a dummy area outside the screen area. In addition, the bracket 140 may preferably be blocked by the blocking portion 1500. Accordingly, as shown in FIG. 15A, it is preferable that the blocking part 1500 overlaps with the bracket 140. The width W10 and W20 of the blocking portion 1500 may be greater than the width W1 of the bracket 140. In this case, W11, W12).

Referring to FIG. 16, it is possible to further arrange a frame 1600 behind the backlight unit 120. In such a case, the structural stability of the backlight unit 120 can be improved, and the uniformity of light can be improved. Preferably, the frame 1600 may be attached to the back surface of the backlight unit 120. [

In this case, the frame 1600 may be fixed to the bracket 140. [ 17, a mounting portion 1700 is formed in the bracket 140, a fastening hole 1610 is formed in the frame 1600, and a fastening means 1720 is fastened to the frame 1600 And can be fixed to the seating portion 1700 of the bracket 140 through the fastening hole 1610.

Referring to FIG. 20, the bracket 140 may extend to the side of the display panel 100. Accordingly, the bracket 140 may include a portion 142 located on a side surface of the display panel 100. For example, the bracket 140 may extend to the side surface of the rear substrate 111 of the display panel 100 so that the bracket 140 may include a portion of the display panel 100 located on a side surface of the rear substrate 111 Or the brackets 140 extend to the side surfaces of the front substrate 101 of the display panel 100 so that the brackets 140 are disposed on the side surfaces of the front substrate 101 and the rear substrate 111 of the display panel 100 And < / RTI > 20, D20 may indicate the direction in which the bracket 140 extends.

In this case, the edge of the front surface of the front substrate 101 can be exposed. In addition, the edge of the side surface of the front substrate 101 may not be exposed. Accordingly, the edge of the side surface of the front substrate 101 can be effectively protected from an external impact.

20, the edge of the side surface of the front substrate 101 is covered with the bracket 140 when the observer looks at the front surface of the front substrate 101 from the side of the display panel 100, All or a part of the side surface of the front substrate 101 may be understood to be all or part of the side surface of the rear substrate 111 or all or a part of the side surface of the front substrate 101 may be obscured by the bracket 140 have.

In other words, the fact that the side edge of the front substrate 101 is covered with the bracket 140 means that all or a part of the side surface of the display panel 101 in the longitudinal direction of the display panel 101, All or a part of the side surface of the front substrate 101 or all or a part of the side surface of the front substrate 101 overlap with the bracket 140. [

Accordingly, the bracket 140 may be provided on the side surface of the display panel 100 And a portion 143 positioned on the front surface of the front substrate 101. In Figure 21A, D10 and D11 may indicate a direction in which the bracket 140 extends.

In this case, a part of the front edge of the front substrate 101 may be covered with the bracket 140, but most of the front surface of the front substrate 101 may still be exposed.

Further, even when the bracket 140 covers a part of the front edge of the front substrate 101, it may not cover all the edges of the front surface of the front substrate 101. For example, as in the case of FIG. 21B, the bracket 140 can cover a part of the edge at the first long side LS1 and the second long side LS2 of the front substrate 101, The edges may still be exposed on the first short side SS1 and the second short side SS2 side.

21A to 21D can be applied to the case where the auxiliary bracket 2300 described below is added. That is, it is also possible to change the bracket 140 to the auxiliary bracket 2300 in the contents of FIGS. 21A to 21D.

22A, when the bracket 140 is extended to the front surface of the front substrate 1010 of the display panel 100, the bracket 140 on the front surface of the front substrate 101 has a portion overlapping the blocking portion 1500 P3. In such a case, the bracket 140 may cover a part of the blocking part 1500. In this case,

Here, the portion P3 of the bracket 140 which overlaps with the blocking portion 1500 may be in contact with the blocking portion 1500.

Even when the bracket 140 covers a part of the blocking part 1500, the size of the area where the bracket 140 and the blocking part 1500 are overlapped is larger than the area where the bracket 140 and the blocking part 1500 do not overlap Lt; / RTI >

For example, the size of the portion P3 blocked by the bracket 140 in the blocking portion 1500 may be smaller than the size of the portion W100 exposed by the bracket 140 in the blocking portion 1500 .

22A to 22D can be applied to the case where the auxiliary bracket 2300 described below is added. That is, it is also possible to change the bracket 140 to the auxiliary bracket 2300 in the contents of FIGS. 22A to 22D.

Referring to FIG. 23A, an auxiliary bracket 2300 can be disposed between the bracket 140 and the back cover 130. As described above, by using the auxiliary bracket 2300, it is possible to easily change the design of the display device by changing the shape of the auxiliary bracket 2300 exposed to the outside without changing the shape of the bracket 140. [ The connection structure and the like of the back cover 130 can be easily changed without changing the arrangement structure of the optical layer 110 or the backlight unit 120 by using the auxiliary bracket 2300. [ That is, the outer shape of the back cover 130 can be easily changed without changing the basic structure of the display device.

One side of the auxiliary bracket 2300 is fixed to the bracket 140 and the back cover 130 is fixed to the other side of the auxiliary bracket 2300.

The auxiliary bracket 2300 is formed with a depression 2310 which is recessed in the direction toward the bracket 140 and the back cover 130 is formed in the depression 2310. In order to fix the back cover 130 to the auxiliary bracket 2300, It is possible to insert the edge of the light guide plate.

Here, the groove 2310 formed in the auxiliary bracket 2300 for fixing the back cover 130 may be referred to as a fourth groove 2310.

When the back cover 130 is fixed to the auxiliary bracket 2300, the back cover 130 and the backlight unit 120 may be separated from each other by a predetermined distance. 14 to 15, when the back cover 130 is fixed to the bracket 140, the back cover 130 may be substantially the same as the case where the back cover 130 and the backlight unit 120 are separated from each other by a predetermined distance have.

Even when the back cover 130 is fixed to the auxiliary bracket 2300, the edge of the front surface of the front substrate 101 is exposed or the edge of the side surface of the front substrate 101 is exposed. Is exposed. This has been described in detail in Figs. 14 to 15 above.

Referring to FIG. 23B, the display panel 100 may include a portion W200 that is longer than the auxiliary bracket 2300 in the longitudinal direction. This has been described in detail above.

Further, the bracket 140 and the auxiliary bracket 2300 can be fastened by a predetermined fastening means. 24, a groove 144 is formed in the bracket 140 for fastening with the auxiliary bracket 2300. The auxiliary bracket 2300 is provided with a hole (not shown) through which the fastening means 2400 passes 2320 may be formed. In this case, the fastening means 2400 such as a screw can be fixed to the groove 144 formed in the bracket 140 through the hole 2320 formed in the auxiliary bracket 2300. Here, the groove 144 for fastening with the auxiliary bracket 2300 formed on the bracket 140 can be referred to as a fifth groove 144.

Referring to FIG. 25, the auxiliary bracket 2300 may include a portion 2330 located on the side of the display panel 100.

That is, the auxiliary bracket 2300 can extend to the side of the display panel 100. [ The auxiliary bracket 2300 extends to the side surface of the rear substrate 111 of the display panel 100 so that the auxiliary bracket 2300 covers a portion of the display panel 100 located on the side surface of the rear substrate 111 Or the auxiliary bracket 2300 extends to the side surface of the front substrate 101 of the display panel 100 so that the auxiliary bracket 2300 is connected to the front substrate 101 and the rear substrate 111 of the display panel 100, As shown in FIG.

26, the auxiliary bracket 2300 may extend to the side surface of the display panel 100 and the front surface of the front substrate 1010. Accordingly, the auxiliary bracket 2300 may be disposed on the front surface of the display panel 100 A portion 2330 located on the side surface and a portion 2340 located on the front surface of the front substrate 101.

In this case, a part of the edge of the front surface of the front substrate 101 may be covered with the auxiliary bracket 2300, but most of the front surface of the front substrate 101 may still be exposed.

Even if the auxiliary bracket 2300 covers a part of the edge of the front surface of the front substrate 101, all the edges of the front surface of the front substrate 101 may not be blocked. The contents of this can be substantially the same as the contents of FIGS. 21B to 21D.

In the case where the auxiliary bracket 2300 extends to the front surface of the front substrate 101 of the display panel 100, the auxiliary bracket 2300 on the front surface of the front substrate 101 has a portion overlapping the blocking portion 1500 P4). In such a case, the auxiliary bracket 2300 may cover a part of the blocking part 1500. [

Here, the portion P4 overlapping the blocking portion 1500 of the auxiliary bracket 2300 may be in contact with the blocking portion 1500.

Even when the auxiliary bracket 2300 covers a part of the blocking part 1500, the size of the area where the auxiliary bracket 2300 and the blocking part 1500 are overlapped is determined by the overlapping of the auxiliary bracket 2300 and the blocking part 1500 Lt; RTI ID = 0.0 > size. ≪ / RTI > The contents of the auxiliary bracket 2300 may be substantially the same as the contents of FIGS. 22B to 22D.

On the other hand, the bracket 140 can be divided into a plurality of units. For example, as in the case of Fig. 27, the bracket 140 can include the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2.

The first brackets 140A1 and 140A2 are attached to the long sides LS1 and LS2 of the rear surface of the rear substrate 111 of the display panel 100 and the second brackets 140B1 and 140B2 are attached to the display (SS1, SS2) side of the rear surface of the rear substrate 111 of the panel 100. In this case,

The first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 may be separated from each other at a corner of the rear surface of the rear substrate 111. [

In this case, the process of attaching the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 to the rear substrate 111 can be facilitated and the cost of the bracket 140 can be reduced, .

In other words, the optical layer 110 can overlap or contact with the first brackets 140A1 and 140A2, and can be spaced apart from the second brackets 140B1 and 140B2 by a predetermined distance.

In this case, the width A10 of the first brackets 140A1 and 140A2 may be different from the width A20 of the second brackets 140B1 and 140B2. Preferably, the width A10 of the first brackets 140A1 and 140A2 to which the optical layer 110 is fixed may be larger than the width A20 of the second brackets 140B1 and 140B2, as in the case of FIG. 29 . Since the second brackets 140B1 and 140B2 are not fixed to the optical layer 110, the width A20 of the second brackets 140B1 and 140B2 may be small.

Or, as in the case of FIG. 30, the optical layer 110 may be fixed to the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2, respectively. Even in this case, the first brackets 140A1 and 140A2 having a length longer than the length of the second brackets 140B1 and 140B2 can provide a main supporting force for the optical layer 110. [ The width A10 of the first brackets 140A1 and 140A2 can be larger than the width A20 of the second brackets 140B1 and 140B2.

The width L10 of the front polarizing film 3400 and the width L11 of the rear polarizing film 3410 are the widths in the cross section of the display panel 100. [

Preferably, the width L10 of the front polarizing film 3400 may be larger than the width L11 of the rear polarizing film 3410. [

In more detail, as in the case of FIG. 35A, the front polarizing film 3400 can include a portion A30 overlapping the bracket 140. FIG. In addition, the bracket 140 may be spaced apart from the rear polarizing film 3410 by a predetermined distance d11 in a direction parallel to the longitudinal direction of the rear substrate 111. In this case, the bracket 140 can be directly attached to the rear substrate 111, so that the adhesion between the bracket 140 and the rear substrate 111 can be improved.

In addition, the front polarizing film 3400 may be spaced apart from the front end of the front substrate 101 by a predetermined distance d12. In this case, the process of attaching the front polarizing film 3400 to the front substrate 101 can be facilitated, and the yield can be improved.

[ 35B shows only the case where the blocking portion 1500 is disposed on the front polarizing film 3400. However, in the case where the blocking portion 1500 is disposed between the front polarizing film 3400 and the front substrate 101 If possible, in this case, the front polarizing film 3400 may include a portion Y1 that extends further in the outward direction of the display panel 100 than the blocking portion 1500.

Here, it is preferable that the gate driver 3900 and the data driver 3910 are formed on the rear substrate 111 in the dummy area DA outside the screen area AA where the image is displayed.

In this case, since the circuit elements necessary for implementing the image can be formed directly on the rear substrate 111, the number or size of the circuit boards disposed outside can be reduced, thereby further reducing the size or thickness of the display device.

40, when the long side LS and the short side SS of the front substrate 101 are longer than the long side LS and the short side SS of the rear substrate 111, the gate driver 3900 The data driver 3910 may be formed in a region OVA that overlaps with the front substrate 101 and the rear substrate 111 in common.

In synchronism with the display timing, the active retard 14 performs the first circularly polarized light for the left eye image and the second circularly polarized light .

On the other hand, the left eye lens of the spectacles used by the viewer may be constituted by a first circularly polarized filter, and the right eye lens may be constituted by a second circularly polarized filter.

Accordingly, the viewer views only the first circularly polarized left eye image through the left eye, and only the second circularly polarized right eye image through the right eye, thereby making it possible to view the 3D image while making the binocular parallax in the time-division manner.

Further, a filter 12 may be further disposed on the front surface of the panel 100. Preferably, the filter 12 may be laminating to the front surface of the panel 100. The filter 12 protects the panel 100 from mechanical defects such as scratches by exposing the panel 12 to the outside. The filter 12 may include an opaque layer 12a disposed in a rim and a transparent layer 12b disposed therein. The opaque layer 12a is provided substantially corresponding to the non-display area (dummy area) of the panel 100 and the transparent layer 12b is formed in the same manner as the screen area of the panel 100. The transparent layer 12b, May be removed from the filter 12.

The opaque layer 12a prevents the bracket 140 from looking out through the panel 100 and is made of the same color as the bracket 140 so that the panel 100 and the bracket 140 140 are integrally made so that the panel 100 and the bracket 140 are not distinguished from each other so that the panel becomes larger than the actual panel.

This opaque layer 12a may be the blocking portion described above.

The bracket 140 holds the optical layer 110 and the backlight unit 120 therein while supporting the panel 100. The bracket 140 has a rectangular planar shape corresponding to the shape of the panel 100, and a groove 13a is formed around the inner wall. A portion of the edge of the panel 100 (hereinafter referred to as " one end ") is fixed while being seated in the groove 13a. The optical layer 110 and the backlight unit 120 are sequentially stacked closely on the back of the panel 100 with the bracket 140 interposed therebetween.

The optical layer 110 may include a prism sheet 110a and a diffusion plate 110b and transmits light transmitted from the backlight unit 120 to the panel 100 to display an image.

The back cover 130 may be made of an iron material to enhance structural stability and may be combined with the bracket 140 through the optical layer 110 and the backlight unit 120 to form the appearance of the device.

50 is a cross-sectional view taken along the line II-II 'in FIG. 49, showing the assembled state of the device.

50, as shown in the drawing, the display device according to the present invention exposes the front surface of the device with the front surface components such as glass omitted.

The panel 100 can be fixed to the bracket 140 by the adhesive member 16 while one end of the panel 100 is seated in the groove 13a provided in the bracket 140. [ Meanwhile, the bracket 140 may include a groove 141 in which the adhesive member 400 is located.

On the other hand, the panel 100 is preferably connected to the bracket 140 at the same height h.

Meanwhile, the backlight unit 120 may include a light emitting portion 17a and a support plate 1600. The light emitting portion 17a may be formed as a direct downward structure by mounting light sources emitting light, for example, a light emitting diode on the substrate, as will be described in detail below. The support plate 1600 structurally supports the light emitting portion 17a And may be made of steel materials such as aluminum or steel having good rigidity. The light emitting portion 17a may be fixed to the support plate 1600 with an adhesive or may be fixed through a mechanical structure such as bolt tightening.

One end of the support plate 1600 is fixed to the boss 13b provided on the bracket 140 through a screw connection and the optical layer 110 is positioned between the backlight unit 120 and the panel 100 in close contact with each other . On the other hand, in order to prevent the optical layer 110 from moving, one end of the optical layer 110 may be fixed to the bracket 140 with an adhesive or may be fixed to the protrusion provided on the bracket 140. Further, a fixer (not shown), which is a mechanical component for fixing the bracket 140 and the optical layer 110, is positioned to remove the space between the bracket 140 and the optical layer 110, May be fixed.

FIG. 51 shows another embodiment of the bracket 140, in which the bracket 140 is formed to surround the edge of the panel 100. FIG. As shown in the figure, the bracket 140 has a shape extending to the inside of the panel 100 while enclosing the rim of the panel 100. At this time, it is preferable that the bracket 140 is disposed so as to cover only the non-display area and the dummy area of the panel 100.

52 shows a state in which one end of the bracket 140 and the panel 100 are arranged on the same line. In this embodiment, the bracket 140 is located on the same line as the end of the panel 100, and the panel 100 and the bracket 140 are coupled to each other through an adhesive or a screw connection.

FIG. 53 illustrates a case where the bracket 140 is divided into a first portion 131 and a second portion 133. That is, the bracket 140 includes a first portion 131 surrounding the periphery of the panel 100, and a space between the backlight unit 120 and the optical layer 110, And a second portion 133 for reducing and holding them to be immovable.

On the other hand, FIG. 54 shows an embodiment in which the backlight unit 120 is fixed by the support pins 23. One end 23a of the support pin 23 is fixed to the bracket 140 through a screw connection and the other end 23b of the support pin 23 extends below the backlight unit 120 while surrounding the backlight unit 120. [ Thus, the backlight unit 120 is fixed by the elasticity of the support pin 23. [

As described above, since the support plate 1600 used to support the backlight unit 120 can be omitted, the thickness of the module (collectively referred to as the backlight unit and the optical layer) can be reduced have.

On the other hand, in the above-described embodiment, the case where the backlight unit is configured as a direct lower type has been described, but it may be configured as an edge type as shown in FIG. 55 shows an embodiment in which the backlight unit is configured as an edge type.

Referring to FIG. 55, the optical layer 110 may further include a light guide plate 110c and a reflection plate 110d.

The light guide plate 110c guides the light incident from the side so that light can be uniformly incident on the entire panel and the reflection plate 110d reflects the light directed toward the back surface to the front surface where the panel 100 is present.

The light guide plate 110c and the reflection plate 110d are sequentially stacked and fixed by the support pin 23. One of the support pins 23 is screwed to the bracket 140, and the other of the support pins 23 extends to below the reflection plate 110d. Accordingly, the optical layer 110 can be held while being supported for the elastic force of the support pin 23.

The backlight unit 31 includes a light emitting diode 31b as a light source and a substrate 31a on which the light emitting diode 31b is mounted and the size and the number of the light emitting diodes are variously changed according to the embodiment . The backlight unit 31 may be fixed to the seating groove 131a by an adhesive. In this case, the seating groove 131a may function to prevent light from leaking. Of course, it is also possible that there is no seat groove as in Fig.

If the backlight unit 31 is configured as an edge type as described above, the thickness of the module can be reduced as compared with the direct type described above.

57, another display device according to the present invention includes a panel 61, a first bracket 63, a second bracket 64, an optical layer 65, a backlight unit 67, (69).

The panel 61 displays the image and is exposed to the front to form the appearance of the apparatus. A filter 62 including a transparent layer 62a and an opaque layer 62b and an active retard 66 for forming a 3D image may be selectively disposed on the entire surface of the panel 61. [

The first bracket 63 holds the optical layer 65 and the backlight unit 67 therein while supporting the panel 61. The first bracket 63 has a " C "shape having an open bottom so as to support three places of the liquid crystal panel 61. [ A recess is formed in the inner side wall of the first bracket 63 so as to support the panel 61.

The optical layer 65 and the backlight unit 67 are sequentially stacked in close contact with the rear surface of the panel 61 with the first bracket 63 interposed therebetween.

Then, the second bracket 64 is disposed under the module.

FIG. 58 is a cross-sectional view taken along the line X-X 'in FIG. 57, showing a bottom fitting state of the device including the second bracket 64. FIG.

In Fig. 58, the second bracket 64 is positioned under the module and forms the appearance of the device. It is preferable that the second bracket 64 is positioned under the module in close contact with the panel 61 and that the second bracket 64 and the surface of the panel 61 are disposed on the same line. As described above, when the second bracket 64 is located on the same line as the surface of the panel 61, the boundary between the second bracket 64 and the panel 61 is eliminated, And it also has the effect of increasing the design of the device.

An electrode 7100 for detecting a change in capacitance may be further formed on the inner surface of the one end of the panel 61. The electrode 7100 is made of a transparent conductive material and may be formed in the form of a lattice-shaped diamond cell. When the user indirectly touches the electrode 7100 with the panel 61 interposed therebetween, the capacitance value changes at the touched point. This value is transmitted to the control unit 7140, By reading the coordinates of the line, the touched position is grasped. Accordingly, the control unit can control the operation of the apparatus by generating a control signal corresponding to the touched position. In one embodiment, the control unit 7140 can control the operation such as up / down the volume of the apparatus or up / down the channel according to the touched position.

In order to increase the touch sensitivity of the electrode 7100, it is preferable that one end of the panel 61 has only one of the upper substrate and the lower substrate, and an electrode is formed on the back surface of the remaining substrate.

The second bracket 64 includes a control unit 7140, a speaker 71 and a remote control receiving module (not shown) connected to the electrode 7100, which is the above-described touch sensor, through a signal line 7110 Elements can be placed, thus hiding the functional module within the second bracket 64, thereby enhancing space utilization in a slim structure.

Such a second bracket 64 can be fixed to the back cover 69 by screwing the back cover 69 and the first bracket 63 can be fixed to the side surface of the second bracket 64 641 and may be fixed to the side of the first bracket 63 with an adhesive or may be fixed to the side of the first bracket 63 and the back cover 69. [

60 is a view showing an embodiment in which the second bracket 64 further includes a protrusion 641 extending to the inside of the panel 61. [ 60, the protrusion 641 is elongated along the longitudinal direction of the second bracket 64, and accordingly, the protrusion 641 is disposed on the lower side of the panel 61. At this time, it is preferable that the protrusions 641 are disposed so as to cover only the non-display area of the panel. Thus, the projecting portion 641 covers the end portion of the structurally weak panel 61, thereby protecting the panel 61 and preventing contaminants such as dust from flowing into the apparatus.

61 to 63 are diagrams for explaining an example of the configuration of the backlight unit. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 61, the backlight unit 6100 includes a first layer 6110, a light source 6120, and a second layer 6130.

A plurality of light sources 6120 are formed in the first layer 6110 and a second layer 6130 is formed above the first layer 6110 to cover the light sources 6120. [

The first layer 6110 may be a substrate on which the light sources 6120 are mounted, and an electrode pattern (not shown) connecting the light sources 6120 is formed on the first layer 6110. Such a substrate 6110 may be composed of a metal PCB formed of a metal such as aluminum that does not conduct electricity.

The light source 6120 may be one of a light emitting diode (LED) chip or a light emitting diode package having at least one light emitting diode chip. It is preferable that the light emitting diode 6120 is a side view type light emitting diode in which the light emitting surface faces the side surface. Also, the light source 6120 emits at least one of the three primary colors of colors such as red, blue, and green, or emits white light.

A second layer 6130 is formed on top of the first layer 6110 in a manner to embed the light sources 6120. The second layer 6130 transmits light emitted from the light source 6120 So that the light emitted from the light source 6120 is uniformly provided to the panel.

A reflective layer 6140 may be further formed between the first layer 6110 and the second layer 6130, that is, on the upper surface of the first layer 6110 to reflect light emitted from the light source 6120. The reflective layer 6140 reflects the light totally reflected from the interface of the second layer 6130 again so that the light emitted from the light source 6120 is spread in a widened state.

The reflective layer 6140 may be formed by dispersing a white pigment such as titanium oxide in a sheet of a synthetic resin material, having a metal vapor deposition film on its surface, dispersing bubbles in a synthetic resin sheet to scatter light, , And silver may be coated on the surface to increase the reflectance. Such a reflective layer 6140 may also be formed in the form of being coated on the first layer 6110. The second layer 6130 may be made of a light-transmissive material, for example, silicon or acrylic resin.

The second layer 6130 may be formed of a resin having a refractive index of about 1.4 to 1.6 so that light emitted from the light source 6120 is diffused and the backlight unit 6100 has a uniform brightness.

The second layer 6130 may be formed by applying a resin in a liquid state or a gel state to the upper side of the plurality of light sources 6120 and the first layer 6110 and curing the resin, Lt; / RTI > may be glued to the top of the first layer 6110 in the state of FIG.

As the thickness of the second layer 6130 increases, the light emitted from the light source 6120 spreads more widely, so that light of a uniform brightness can be provided to the panel from the backlight unit 6100. On the other hand, as the thickness of the second layer 6130 increases, the amount of light absorbed in the second layer 6130 increases, so that the brightness of the light can be reduced.

Therefore, it is preferable that the thickness a of the second layer 6130 is 0.1 to 4.5 (mm) in order to obtain light of a uniform brightness without reducing the brightness of light supplied from the backlight unit 6100 to the panel.

62, a side light emitting diode 6120 is disposed.

These light emitting diodes 6120 emit light in the lateral direction. Thus, in order for the backlight unit 6100 to exhibit uniformly uniform brightness, the light emitting diodes 6120 are arranged to form two or more rows. Here, the light emitting diodes 6120 disposed in the same row emit light in the same direction.

For example, the light sources adjacent to the first light source 6120 in the left and right directions also emit light in the same direction (arrow direction in the figure) as the first light source 6120, and the light sources adjacent to the left and right of the second light source 6121 emit light (In the direction opposite to the arrow in the figure) opposite to the one light source 6120.

As described above, since the light emitting diodes 6120 and 6121 emit light in mutually opposite directions along the rows, it is possible to reduce the phenomenon that the brightness of light is concentrated or weakened in a specific region of the backlight unit 6100.

The backlight unit 6100 thus formed may be driven by a whole driving method or a partial driving method such as local dimming, impulse, or the like.

That is, the backlight unit 6100 can be divided into a plurality of divided driving regions, and by driving the luminance of the divided driving region in accordance with the luminance of the video signal, the display quality of the image such as contrast ratio and sharpness can be improved. Accordingly, a plurality of backlight units 6100 may also be formed. For example, a plurality of optical assemblies 6101 shown in FIG. 63 may be combined to constitute one backlight unit 6100. In this case, only a part of the optical assemblies 6101 can be independently driven to emit light, and the light sources 6120 included in each of the optical assemblies 6101 can be independently controlled thereby.

On the other hand, the area of the panel corresponding to one optical assembly 6101 can be divided into two or more blocks, and the panel and the backlight unit 6100 can be dividedly driven in the block unit. As such, when the backlight unit 6100 is composed of a plurality of optical assemblies 6101, the manufacturing process of the backlight unit 6100 can be simplified, and the loss that may occur in the manufacturing process can be minimized. In addition, the backlight unit 6100 can be applied to backlight units of various sizes by mass-producing the optical assembly 6101 in a standardized standard.

In addition, when a failure occurs in the light emitting diode provided in the backlight unit 6100, only the corresponding optical assembly 6101 can be selectively replaced without replacing the entire backlight unit 6100, It is possible to reduce the replacement cost of the parts.

Figs. 64 to 79 are views for explaining another method of arranging the optical layers. Fig. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 64, the optical layer 110 is not fixed to the bracket 140 but may be placed on one side of the bracket 140. In this case, the optical layer 110 may be movable at the upper portion of the bracket 140. [

Here, although the shape of the bracket 140 is different from that described above, the shape of the bracket 140 of Fig. 64 may be the same as that of Fig. 4, for example. The shape of the bracket 140 is not limited.

In this structure, since the optical layer 110 is simply placed on the bracket 140, the manufacturing process can be simplified. If the optical layer 110 is designed to have a size corresponding to the size of the bracket 140, even if the optical layer 110 is simply placed on the bracket 140, the optical layer 110 Can be limited.

When the optical layer 110 is disposed on the bracket 140 as described above, the optical layer 110 and the rear substrate 111 of the display panel 100 may be separated from each other by a predetermined distance Z1, An air gap 6500 may be formed between the rear substrate 111 and the optical layer 110, as in the case of FIG.

In this way, when an air gap 6500 is formed between the rear substrate 111 and the optical layer 110, the optical characteristics of the display device can be improved by the air layer 6500.

Referring to FIG. 66, a fixing portion 6600 may be disposed on one surface of the bracket 140, and the optical layer 110 may be disposed on the fixing portion 6600. The fixing portion 6600 may have a shape protruding in a direction away from the display panel 100.

As described above, when the optical layer 110 is disposed on the fixing portion 6600, since the size of the contact surface between the optical layer 110 and the fixing portion 6600 is relatively small, damage to the optical layer 110 is suppressed It is possible.

It is also possible that the fixing portion 6600 which contacts the optical layer 110 to prevent the optical layer 110 from moving and sufficiently prevent damage to the optical layer 110 has a property that is more rigid than the bracket 140 . For example, the fixing portion 6600 may include a polyurethane material.

And the light guide plate 7000 can be disposed behind the optical layer 110. [

The maximum height Z2 of the optical layer 110 measured from the back surface of the rear substrate 111 may be smaller than the height Z3 of the bracket 140 in order to prevent the optical layer 110 from being separated.

The maximum height Z4 of the light guide plate 7000 measured from the rear surface of the rear substrate 111 to prevent the light guide plate 7000 from deviating even when the light guide plate 7000 is disposed behind the optical layer 110 May be smaller than the height (Z3) of the bracket (140).

In addition, the fixing portion 6600 can have a stripe shape as in the case of Fig. In this case, one fixing portion 6600 may be disposed on one bracket 140. [

Alternatively, the fixing portion 6600 may be plural as in the case of Fig. That is, the plurality of fixing portions 6600 can be disposed on one bracket 140. In this case, the size of the contact surface between the fixing portion 6600 and the optical layer 110 can be further reduced.

Referring to FIG. 69, a frame 1600 may be disposed behind the optical layer 110.

Such a frame 1600 may be fixed to the bracket 140. For example, the bracket 140 may include a protrusion 145 protruding in a direction D30 away from the display panel 100, and the frame 1600 may be connected to the protrusion 145. In this case, although not shown, it is possible to connect the frame 1600 and the projecting portion 145 of the bracket 140 using a fastening means such as a screw.

In this structure, it is possible that the backlight unit 120 is disposed between the frame 1600 and the optical layer 110 when a direct-type light source is provided.

70, a light guide plate 7000 may be disposed between the frame 1600 and the optical layer 110, and an edge-type light guide plate 7000 may be provided on the side surface of the light guide plate 7000. In this case, The backlight unit 7010 of FIG. Such an edge-type backlight unit 7010 may include a substrate 7011 and a light source 7012 such as an LED disposed on the substrate 7011.

The display device according to the present invention may include an edge type backlight unit 7010, or may include a direct type backlight unit. In the present invention, both edge type and direct type can be possible without special mention.

Referring to FIG. 71, a back cover 130 may be disposed behind the frame 1600.

In addition, the back cover 10 may be fixed to the bracket 140. 71, the back cover 130 can be fastened and fixed to the projecting portion 145 of the bracket 140 by a predetermined fastening means (not shown). A frame 1600 may be connected to one side of the protrusion 145 of the bracket 140 and a back cover 130 may be connected to the other side of the protrusion 145. [ In this case, a part of the frame 1600 and a part of the back cover 130 can face each other with the bracket 140 therebetween.

72, a driving board 7210 for supplying a driving signal to the display panel 100 may be disposed between the frame 1600 and the back cover 130. In addition,

In addition, an air layer 7200 may be formed between the frame 1600 and the back cover 130. The air layer 7200 may be formed by providing a space for disposing the driving board 7210 between the frame 1600 and the back cover 130.

The air layer 6500 formed between the optical layer 110 and the rear substrate 111 is referred to as a first air gap and the air layer 6500 formed between the frame 1600 and the back cover 130 The thickness Z5 of the second air layer 7200 may be greater than the thickness Z1 of the first air layer 6500 when the air layer 7200 is referred to as a second air gap.

Referring to FIG. 73, the bracket 140 may be connected to the auxiliary bracket 2300. In addition, it is possible that the back cover 130 is fixed to the auxiliary bracket 2300. A groove 2310 is formed in the auxiliary bracket 2300 and an edge of the back cover 130 is inserted into the groove 2310. [

74, it is possible to insert the end of the back cover 130 into the groove 2310 of the auxiliary bracket 2300 in a roll state. In this case, the coupling force between the auxiliary bracket 2300 and the back cover 130 can be improved. In addition, it is possible to firmly connect the auxiliary bracket 2300 and the back cover 130 without using a fastening means such as a screw.

In addition, the end of the back cover 130 may be curled in the direction toward the center of the display panel 100 in order to prevent the penetration of foreign matter, improve the workability, and enhance the aesthetic appearance.

Here, although the shape of the auxiliary bracket 2300 is different from that of FIGS. 23A to 23B, the shape of the auxiliary bracket 2300 of FIG. 73 is the same as that of FIGS. 23A to 23B. The shape of the auxiliary bracket 2300 is not limited.

75, the auxiliary bracket 2300 may include a portion 2330 located on the side surface of the display panel 100. [

The bracket 140 and the auxiliary bracket 2300 can be spaced apart from each other by a predetermined distance Z10 in the longitudinal direction D31 of the display panel 100. [ That is, it is possible to form an air layer between the bracket 140 and the auxiliary bracket 2300 in the longitudinal direction D31 of the display panel 100. [

In such a case, the overall weight can be reduced while the appearance of the display device is enhanced. It is also possible to prevent the display panel 100 from being damaged by contact with the auxiliary bracket 2300 by preventing the auxiliary bracket 2300 from contacting the display panel 100.

76, when the optical layer 110 is placed on the bracket 140, the bracket 140 may include a portion 142 located on the side surface of the display panel 100.

Alternatively, as in the case of FIG. 77, the back cover 130 may extend to the side surface of the display panel 100. FIG. That is, the back cover 130 may include a portion 132 located on a side surface of the display panel 100.

78, the side surface of the adhesive layer 400 disposed between the bracket 140 and the rear substrate 111 may be exposed. In this case, the width of the adhesive layer 400 can be made larger, and it is possible to improve the adhesive force.

In this case, the adhesive layer 400 can be formed by applying an adhesive material between the rear substrate 111 and the bracket 140, or the adhesive sheet can be formed between the rear substrate 111 and the bracket 140 It is also possible to form the adhesive layer 400 by a method of attaching the adhesive layer 400 to the substrate. For example, it is also possible to form the adhesive layer 400 using an adhesive sheet in the form of a double-sided tape.

79, the thickness Z11 of the front substrate 101 and the thickness Z10 of the rear substrate 111 of the display panel 100 may be different from each other.

Since the edge of the front surface of the front substrate 101 of the display panel 100 may be exposed in the display device according to the present invention, in order to prevent breakage of the front substrate 101, It is preferable that the thickness Z11 is thick. In this case, the thickness Z11 of the front substrate 101 may be greater than the thickness Z10 of the rear substrate 111. [

80 to 92 are views for explaining another configuration of the display device according to the present invention. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 80, in the display device according to the present invention, the bracket 140 may be disposed in a dummy area (DA) outside the active area AA of the display panel 100. Accordingly, the bracket 140 and the display panel 100 may not overlap with each other in the width direction of the display panel 100. That is, the bracket 140 is separated from the end P10 of the effective area AA of the display panel 100 by a predetermined distance F2.

The bracket 140 is attached to the display panel 100 at a position spaced apart from the effective area AA by a predetermined distance F2 in order to prevent screen distortion.

If the user views the display panel in a diagonal direction on the side of the display panel, the image of the boundary portion between the effective area AA and the dummy area DA may be distorted. It is possible to prevent the screen distortion by attaching the bracket 140 to a position spaced a predetermined distance F2 from the effective area AA of the display device.

The interval F1 between the rear substrate 111 and the optical layer 110 is equal to the interval F2 from the end P10 of the active area AA of the display panel 100 to the bracket 140, . ≪ / RTI >

The boundary line BL between the effective area AA in which the image of the display panel 100 is displayed and the dummy area DA in which no image is displayed, The distance F2 from the end P10 of the effective area AA of the display panel 100 to the bracket 140 is smaller than the distance F2 between the rear substrate 111 and the bracket 140, May be smaller than or equal to the interval (F1) between the optical layers (110).

In this case, it is possible to prevent the size of the dummy area DA from being excessively increased.

In order to prevent screen distortion more effectively at the boundary between the effective area AA and the dummy area DA and to prevent the size of the dummy area DA from increasing excessively, The angle? 1 between the normal line TL and the boundary line BL can be set to approximately 15 to 30 mm when the normal line TL that contacts the bracket 140 is set from the end P10 of the boundary line BL .

Here, the distinction between the effective area AA and the dummy area DA will be described below.

81, it is possible to distinguish the dummy area DA from the effective area AA by the seal part 200 disposed between the front substrate 101 and the rear substrate 111 of the display panel 100 . For example, the outer portion of the seal portion 200 may be divided into a dummy region DA, and the inner portion of the seal portion 200 may be divided into an effective region AA. More specifically, it is possible to distinguish the effective area AA and the dummy area DA from the inner surface of the cross section of the seal 200, that is, the surface in contact with the liquid crystal layer 104. [

Alternatively, as in the case of FIG. 82, the effective area AA may be located inside the seal 200.

For example, a plurality of transistors 103 may be disposed inside the seal portion 200. The first transistor 103A closest to the seal portion 200 among the plurality of transistors 103 is always off The second, third, and fourth transistors 103B, 103C, and 103D, which are disposed closer to the center of the display panel 100 than the first transistor 103A, Off operation to contribute to image display.

In this case, the boundary line BL may be positioned between the first transistor 103A and the second transistor 103B. That is, the dummy area DA and the effective area AA can be distinguished by the first transistor 103A and the second transistor 103B.

Alternatively, as in the case of FIG. 83, the dummy area DA and the effective area AA can be distinguished from each other with the outermost pixel on which an image is displayed by supplying data among a plurality of pixels (Pixels 8300).

The method of distinguishing the dummy area DA from the effective area AA is not limited to this.

84, the light guide plate 7000 disposed on the upper portion of the optical layer 110 may protrude by a predetermined length F3 in the outward direction of the display panel 100 as compared with the optical layer 110. FIG.

In such a case, the total length L30 of the light guide plate 7000 may be longer than the total length L310 of the optical layer 110, as in the case of FIG.

When the length L30 of the light guide plate 7000 is longer than the length L31 of the optical layer 110, distortion of the screen is prevented at the boundary portion between the dummy area DA and the effective area AA, 110 can be reduced, so that the manufacturing cost can be reduced.

84, since the optical layer 110 is disposed under the light guide plate 7000, even when the length of the optical layer 110 is short, the light passes through the end P10 of the effective area AA of the display panel 100 It can be seen that the normal line TL contacting the bracket 140 passes both the optical layer 110 and the light guide plate 7000. [

86, the width W3 of the bracket 140 may be larger than the width W4 of the adhesive layer 400. [ In this case, the groove 141 may be formed in the bracket 140 and the adhesive layer 400 may be formed in the groove 141.

86, from the end of the groove 141 to the end of the bracket 140 in the direction D34 toward the center of the display panel 100 with respect to the groove 141 in the cross section of the bracket 140 The first interval W5 may be smaller than the width W4 of the grooves 141. In other words,

The distance W6 from the end of the groove 141 to the end of the bracket 140 in the direction D35 away from the center of the display panel 100 with respect to the groove 141 in the cross section of the bracket 140 And the second gap W6 may be smaller than the width W4 of the groove 141. [

In this case, since the size of the groove 141 formed in the bracket 140 can be increased, the adhesion between the bracket 140 and the rear substrate 111 can be improved.

The sum W5 + W6 of the first gap W5 and the second gap W6 may be smaller than the width W4 of the groove 141. [ In this case, since the size of the groove 141 formed in the bracket 140 can be further increased, the adhesion between the bracket 140 and the rear substrate 111 can be further improved.

Also, the first interval W5 may be less than or equal to the second interval W6. In this case, it is possible to increase the distance between the bracket 140 and the end P10 of the effective area AA of the display panel 100 while maintaining the strength of the bracket 140, thereby further preventing screen distortion Do.

The width W4 of the adhesive layer 400 may be larger than the thickness W7 of the adhesive layer 400. [ In this case, the adhesion between the bracket 140 and the rear substrate 111 can be improved.

The adhesive layer 400 may be formed using a UV adhesive or a polyurethane adhesive.

A case of forming the adhesive layer 400 using a UV adhesive will be described below.

FIG. 87 shows data obtained by measuring the tensile strength (Shear Strength, SST) when the thickness of the adhesive layer 400 formed of the UV adhesive is approximately 25 μm to 450 μm. Here, UV light having a light intensity of 4500? 1500 mJ / cm ² was irradiated to the UV adhesive to form the adhesive layer 400.

Referring to FIG. 87, it can be seen that the tensile strength is maximum when the thickness of the adhesive layer 400 formed of the UV adhesive is approximately 200 μm to 300 μm.

Therefore, when the adhesive layer 400 is a UV adhesive, the adhesive layer 400 may preferably have a thickness of about 200 to 300 mu m.

A case where the adhesive layer 400 is formed using an adhesive of polyurethane is as follows.

88 shows data on the measurement of the shear strength (SST) when the thickness of the adhesive layer 400 formed of the polyurethane adhesive is approximately 0.1 mm to 2.5 mm. The process conditions for forming the adhesive layer 400 are a curing time of about 15 hours and a pressure of about 1 kg / cm ² .

88, it can be seen that the tensile strength is maximum when the thickness of the adhesive layer 400 formed of the polyurethane adhesive is approximately 0.4 mm to 1.0 mm.

Therefore, when the adhesive layer 400 is made of a polyurethane adhesive, it is preferable that the thickness of the adhesive layer 400 is about 0.4 mm to 1.0 mm.

Referring to FIG. 89, one surface of the bracket 140 may have an oblique shape. For example, the side surface of the bracket 140 in the direction D34 toward the center of the display panel 100 of the cross section of the bracket 140 may have a slanting shape when viewed from the rear substrate 111 .

The distance F2 from the end P10 of the effective area AA of the display panel 100 to the bracket 140 is equal to the distance F2 between the bracket 140 and the rear substrate 111, And the adjacent region of the optical layer 111. [ That is, the distance F2 from the end P10 of the effective area AA of the display panel 100 to the bracket 140 can be reduced as the distance from the rear substrate 111 to the optical layer 110 increases.

In this case, screen distortion can be reduced by reducing the blocking of light by the bracket 140. Referring to FIG. 89, it can be seen that the bracket 140 does not touch the normal line TL in the case of FIG. 80 in the case of FIG. 89.

In this case, it can be seen that the bracket 140 includes a portion where the height of the cross section gradually decreases toward the center direction D 34 of the display panel 110. In FIG. 89, the height of the cross section of the bracket 140 can be confirmed as a portion reduced from T11 to T10.

Referring to FIG. 90, the adhesive layer 400 may overlap the optical layer 110 in the width direction of the display panel 100. The reason why the adhesive layer 400 can overlap with the optical layer 110 is that the bracket 140 is formed in a sloped shape so that the bracket 140 can be moved closer to the center of the display panel 100 It is because.

90, when a portion of the bracket 140 which overlaps the optical layer 110 in the width direction of the display panel 100 is referred to as a first portion F5, the first portion F5 corresponds to the display panel 100 And a second portion F6 in which the height T _B gradually decreases toward the center direction D34 of the center portion D2.

Here, the second portion F6 can overlap the portion F7 of the adhesive layer 400 in the width direction of the display panel 100. [

The width of the second portion F6 is set to be greater than the width of the bracket 140 from the end P10 of the effective area of the display panel 100 in order to prevent excessive increase in the size of the dummy area DA while reducing screen distortion. May be smaller than the shortest interval (F2).

91, the second portion F6 of the bracket 140 does not overlap the adhesive layer 400 in the width direction of the display panel 100, but is spaced apart from the adhesive layer 400 by a predetermined distance F8 .

Alternatively, as in the case of FIG. 92, one side of the bracket 140 may have a step shape instead of a slant shape.

Hereinafter, a video display device using a display device according to the present invention will be described. In the following, description of the parts that have been described in detail above will be omitted.

For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme and may include DVB-SI information in the DVB scheme .
