First, referring to FIG. 4, an adhesive layer 400 may be formed between the rear surface of the rear substrate 111 of the display panel 100 and the bracket 140. The bracket 140 may be attached to the rear surface of the rear substrate 111 of the display panel 100 by the adhesive layer 400.

As such, when the bracket 140 is attached to the rear surface of the rear substrate 111 using the adhesive layer 400, support means such as a pemnut, a boss, and fastening means such as a screw may not be used. Since it is not necessary, the fixing can be simplified, the manufacturing cost can be reduced, and the thickness of the display device can be reduced.

In order to improve adhesion between the bracket 140 and the rear substrate 111, a groove 141 is formed on one surface of the bracket 140 facing the rear substrate 111, and an adhesive layer 400 is formed on the groove 141. It may be desirable. As such, the groove 141 formed in the bracket 140 to form the adhesive layer 400 may be referred to as a first groove.

The depth of 141 may include portions A1 and A2 that gradually increase or decrease.

For example, the depth t1 of the center portion of the groove 141 may be different from the depth t2 of the edge portion of the groove 141. In addition, the length of the groove 141 may be gradually reduced at the edge portion of the groove 141.

In other words, the adhesive layer 400 formed in the groove 141 may include portions having different thicknesses. For example, the adhesive layer 400 may have a width at the center portion greater than a width at the edge portion.

Referring to FIG. 6, an optical layer 110 may be disposed in an inner area IA of the bracket 140. In addition, the display panel 100 may extend in an outer area (OA) of the bracket 140.

In this case, when the viewer looks at the display panel 100 from the front of the display panel 100, the observer can observe most of the region of the display panel 100, and thus can be beautiful in appearance. In addition, since another edge may not be seen on the side of the display panel 100, a visual effect that the screen area becomes larger may be obtained.

In this case, an edge of the front surface of the front substrate 101 and an edge of the side surface of the front substrate 101 may be exposed at the upper side ① and the lower side ② of the display panel 100, respectively.

In addition, referring to FIG. 15A, it can be seen that the optical layer 110 is disposed on the inner side IA of the bracket 140.

All or part of the side of the front substrate 101 may mean that all or part of the bracket 140 and overlap.

Alternatively, as shown in FIG. 21A, the bracket 140 may extend to the side of the display panel 100 and the front of the front substrate 1010. Accordingly, the bracket 140 may be disposed on the side of the display panel 100. FIG. A portion 142 and a portion 143 positioned in front of the front substrate 101 may be included in FIG. 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 by the bracket 140, but almost all of the front surface of the front substrate 101 may still be exposed.

In addition, 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 shown in FIG. 21B, the bracket 140 may cover a part of the edge at the first long side LS1 and the second long side LS2 of the front substrate 101, but the front substrate 101 may be partially covered by the front substrate 101. The edge may still be exposed at the first short side SS1 and the second short side SS2 of the side.

Alternatively, as shown in FIG. 21C, the bracket 140 may cover a part of the edge at the first short side SS1 and the second short side SS2 of the front substrate 101, but the first substrate side of the front substrate 101 may be formed. The edges may still be exposed at the first long side LS1 and the second long side LS2.

Alternatively, as shown in FIG. 21D, the bracket 140 is edged at the first long side LS1, the second long side LS2, the first short side SS1, and the second short side SS2 of the front substrate 101. Although it is possible to cover a part of, in this case almost all of the front of the front substrate 101 may still be exposed.

21A to 21D may be applied to the case where the auxiliary bracket 2300 described below is added. That is, in the contents of FIGS. 21A to 21D, the bracket 140 may be changed to the auxiliary bracket 2300.

Referring to FIG. 22A, when the bracket 140 extends to the front of the front substrate 1010 of the display panel 100, the bracket 140 is overlapped with the blocking unit 1500 at the front of the front substrate 101. It is possible to include P3) In this case, the bracket 140 may cover a part of the blocking unit 1500.

Here, the portion P3 overlapping with the blocking portion 1500 of the bracket 140 may contact the blocking portion 1500.

In addition, even when the bracket 140 covers a part of the blocking unit 1500, the size of the region where the bracket 140 and the blocking unit 1500 overlap with each other is an area where the bracket 140 and the blocking unit 1500 do not overlap. It may be less than the size of.

For example, the size of the portion P3 covered by the bracket 140 in the blocking unit 1500 may be smaller than the size of the portion W100 exposed without being covered by the bracket 140 in the blocking unit 1500. Can be.

In addition, as shown in FIG. 22B, the bracket 140 may cover a part of the blocking part 1500 on the first long side LS1 and the second long side LS2 of the front substrate 101, but the front substrate ( On the first short side SS1 and the second short side SS2 of the 101, the blocking unit 1500 may be exposed without being blocked by the bracket 140.

Alternatively, as shown in FIG. 22C, at the first short side SS1 and the second short side SS2 of the front substrate 101, the bracket 140 may cover a part of the blocking part 1500, but the front substrate ( On the first long side LS1 and the second long side LS2 of the 101, the blocking unit 1500 may be exposed without being covered by the bracket 140.

Alternatively, as shown in FIG. 22D, the blocking unit 1500 may be disposed on the first long side LS1, the second long side LS2, the first short side SS1, and the second short side SS2 of the front substrate 101. It is possible for the bracket 140 to cover a part, but even in this case, most of the blocking unit 1500 may still be exposed.

22A to 22D may be applied to the case where the auxiliary bracket 2300 described below is added. That is, in the contents of FIGS. 22A to 22D, the bracket 140 may be changed to the auxiliary bracket 2300.

Referring to FIG. 23A, an auxiliary bracket 2300 may be disposed between the bracket 140 and the back cover 130. As such, when the auxiliary bracket 2300 is used, the design of the display device can be easily changed by changing the shape of the auxiliary bracket 2300 exposed to the outside without changing the shape of the bracket 140. In detail, the connection structure of the back cover 130 can be easily changed without changing the arrangement of the optical layer 110 or the backlight unit 120 using the auxiliary bracket 2300. That is, the basic structure of the display device can be easily changed without changing the connection structure of the back cover 130.

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

In order to fix the back cover 130 to the auxiliary bracket 2300, a recess 2310 is formed in the auxiliary bracket 2300 in the direction toward the bracket 140, and the back cover 130 is formed in the groove 2310. It is possible for the edge of to be inserted.

Here, the groove 2310 formed in the auxiliary bracket 2300 to fix 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 spaced apart from each other by a predetermined distance. As described above with reference to FIGS. 14 to 15, when the back cover 130 is fixed to the bracket 140, the back cover 130 and the backlight unit 120 may be substantially the same as the predetermined distances. have.

In addition, 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 side edge of the side of the front substrate 101 is exposed. It is possible to be exposed. This has been described in detail with reference to FIGS. 14 to 15.

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

In addition, the bracket 140 and the auxiliary bracket 2300 may be fastened by a predetermined fastening means. For example, as shown in FIG. 24, the groove 140 for fastening with the auxiliary bracket 2300 is formed in the bracket 140, and the hole through which the fastening means 2400 passes through the auxiliary bracket 2300. 2320 may be formed. In this case, the fastening means 2400 such as a screw may be fixed to the groove 144 formed in the bracket 140 by passing through the hole 2320 formed in the auxiliary bracket 2300. Here, the groove 144 for fastening with the auxiliary bracket 2300 formed in the bracket 140 may be referred to as a fifth groove 144.

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

That is, the auxiliary bracket 2300 may extend to the side of the display panel 100. For example, the auxiliary bracket 2300 extends to the side of the rear substrate 111 of the display panel 100 so that the auxiliary bracket 2300 is located at the side of the rear substrate 111 of the display panel 100. Or, the auxiliary bracket 2300 extends to the side of the front substrate 101 of the display panel 100 so that the auxiliary bracket 2300 is the front substrate 101 and the rear substrate 111 of the display panel 100. It may include a portion located on the side of).

Alternatively, as shown in FIG. 26, the auxiliary bracket 2300 may extend to the side of the display panel 100 and the front of the front substrate 1010. Accordingly, the auxiliary bracket 2300 may be formed of the display panel 100. It may include a portion 2330 positioned on the side and a portion 2340 positioned 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 by the auxiliary bracket 2300, but most of the front surface of the front substrate 101 may still be exposed.

In addition, even when the auxiliary bracket 2300 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. The contents may be substantially the same as the contents of FIGS. 21B to 21D.

In addition, when 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 overlaps with the blocking unit 1500 ( It is possible to include P4). In this case, the auxiliary bracket 2300 may cover a part of the blocking unit 1500.

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

In addition, even when the auxiliary bracket 2300 covers a part of the blocking unit 1500, the size of the region where the auxiliary bracket 2300 and the blocking unit 1500 overlap the size of the auxiliary bracket 2300 and the blocking unit 1500. It may be smaller than the size of the non-region. 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 may be divided into a plurality. For example, as in the case of FIG. 27, the bracket 140 may include the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2.

Here, 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 displayed on the display panel 100. It is possible to be attached to the short side (SS1, SS2) side of the back of the rear substrate 111 of the panel 100.

In addition, the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 may be spaced apart from each other by a predetermined interval d10. Preferably, the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 may be spaced apart from each other at a corner portion of the rear surface of the rear substrate 111.

In this case, a process of attaching the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 to the rear substrate 111 may be facilitated, and the total manufacturing cost may be reduced by lowering the unit cost of the bracket 140. Can be.

In addition, the optical layer 110 may be fixed to at least one of the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2. For example, as in the case of Figure 28, the optical layer 110 is fixed to the first bracket (140A1, 140A2) of the first bracket (140A1, 140A2) and the second bracket (140B1, 140B2), the second bracket It may not be fixed to 140B1 and 140B2. In other words, the optical layer 110 may overlap or contact the first brackets 140A1 and 140A2, and may be spaced a predetermined distance without overlapping the second brackets 140B1 and 140B2.

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, as in the case of FIG. 29, 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. . Since the optical layer 110 is not fixed to the second brackets 140B1 and 140B2, the width A20 may be small.

Alternatively, as shown in 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 lengths of the second brackets 140B1 and 140B2 may provide the main supporting force for the optical layer 110. Accordingly, the width A10 of the first brackets 140A1 and 140A2 may be larger than the width A20 of the second brackets 140B1 and 140B2.

In addition, the first bracket 140A1 and 140A2 and the second bracket 140B1 and 140B2 may be connected by a predetermined connection means. For example, as shown in FIG. 31, the connection part 3100 may be disposed between the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 spaced apart from each other, and the connection part 3100 may be predetermined. The first bracket (140A1, 140A2) and the second bracket (140B1, 140B2) can be connected by being connected to the first bracket (140A1, 140A2) and the second bracket (140B1, 140B2) by the fastening means (3110) of the. .

Referring to FIG. 32, the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2 may be integrally formed. In this case, the portions disposed on the long sides LS1 and LS2 of the rear substrate 111 in the bracket 140 are called first brackets 140A1 and 140A2 and disposed on the short sides SS1 and SS2 of the rear substrate 111. It is possible to call the second brackets 140B1 and 140B2.

Even in this case, it is possible for the width A10 of the first brackets 140A1 and 140A2 to be larger than the width A20 of the second brackets 140B1 and 140B2.

Referring to FIG. 33, a single auxiliary bracket 2300 may be connected to the first brackets 140A1 and 140A2 and the second brackets 140B1 and 140B2. In this case, between the first bracket (140A1, 140A2) and the second bracket (140B1, 140B2) while the auxiliary bracket (2300) is connected to the first bracket (140A1, 140A2) and the second bracket (140B1, 140B2). An empty space may be provided.

Referring to FIG. 34, the width L10 of the front polarizing film 3400 disposed on the front surface of the front substrate 101 of the display panel 100 and the rear polarizing film 3410 disposed on the rear surface of the back substrate 111 are shown. The width L11 may be different from each other. Here, 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.

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

In addition, the front polarizing film 3400 may be spaced apart from the end of the front surface 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 may be facilitated, and the yield may be improved.

Referring to FIG. 35B, the blocking unit 1500 and the front polarizing film 3400 may overlap. For example, the blocking unit 1500 may include a portion disposed above the front polarizing film 3400.

In addition, the front polarizing film 3400 may include a portion Y1 that extends more than the blocking portion 1500 in the outer direction of the display panel 100. In FIG. 35B, only the blocking part 1500 is disposed on the front polarizing film 3400, but the blocking part 1500 is disposed between the front polarizing film 3400 and the front substrate 101. If possible, even in this case, the front polarizing film 3400 may include a portion Y1 that extends more than the blocking portion 1500 in the outer direction of the display panel 100.

Alternatively, as illustrated in FIG. 35C, the blocking unit 1500 may include a portion Y2 that extends more than the front polarizing film 3400 in the outward direction of the display panel 100. In this case, the blocking unit 1500 may also be in contact with the front polarizing film 3400 and may also be in contact with the front substrate 101.

In FIG. 35C, only the blocking part 1500 is disposed on the front polarizing film 3400, but the blocking part 1500 is disposed between the front polarizing film 3400 and the front substrate 101. If possible, even in this case, the blocking unit 1500 may include a portion Y2 that extends more than the front polarizing film 3400 in the outer direction of the display panel 100.

Alternatively, the blocking unit 1500 and the front polarizing film 3400 may be formed on the same layer. In this case, the blocking unit 1500 may be disposed outside the front polarizing film 3400.

Referring to FIG. 36, when the bracket 140 is spaced apart from the rear polarizing film 3410 in a direction parallel to the longitudinal direction of the rear substrate 111 by a predetermined distance d11, the bracket 140 may be disposed on the optical layer 110. An air layer 3600 may be formed between the bracket 140 and the rear polarizing film 3410 in a state of being disposed inside.

In addition, when the auxiliary bracket 2300 includes a portion located on the side of the display panel 100, the front polarizing film 3400 and the auxiliary bracket 2300 are a predetermined distance d22 from the front of the front substrate 101. Can be spaced apart. The same may be applied to the case where the auxiliary bracket 2300 is not used and the bracket 140 includes a portion located on the side of the display panel 100.

Referring to (a) and (b) of FIG. 37, the short sides SS1 and SS2 of the front substrate 101 extend longer than the short sides SS1 and SS2 of the rear substrate 111, and the long sides of the front substrate 101. The LS1 and LS2 may extend further than the long sides LS1 and LS2 of the rear substrate 111.

For example, the first short side SS1 of the short side SS of the front substrate 101 may be smaller than the first short side SS1 of the back substrate 111 corresponding to the first short side SS1 of the front substrate 101. The second short side SS2 extending by the first length S1, and the second short side SS2 of the short sides of the front substrate 101 corresponds to the second short side SS2 of the front substrate 101 ( It is possible to extend by the second length S2 rather than SS2).

Here, the first length S1 and the second length S2 may be substantially the same.

Alternatively, the first length S1 and the second length S2 may be different from each other. In this case, the structures of the first short side SS1 and the second short side SS2 of the front substrate 101 of the display panel 100 may be different from each other.

For example, the first short side SS1 of the rear substrate 111 for mounting a gate driver on the first short side SS1 of the rear substrate 111 corresponding to the first short side SS1 of the front substrate 101. A large enough space can be provided on the side. In this case, the first length S1 may be smaller than the second length S2.

The first long side LS1 of the long side LS of the front substrate 101 is connected to the first long side LS1 of the rear substrate 111 corresponding to the first long side LS1 of the front substrate 101, And the second long side LS2 of the long side LS of the front substrate 101 is extended to the second long side LS2 of the rear substrate 111 corresponding to the second long side LS2 of the front substrate 101 (S20) than the second length LS2.

Here, the twentieth length S20 and the tenth length S10 may be different from each other.

As such, when the long side LS and the short side SS of the front substrate 101 extend longer than the long side LS and the short side SS of the rear substrate 111, as shown in FIG. 38, the front substrate ( An interval X1 between the 101 and the auxiliary bracket 2300 may be different from an interval X2 between the rear substrate 111 and the auxiliary bracket 2300. Preferably, the distance X1 between the front substrate 101 and the auxiliary bracket 2300 may be smaller than the distance X2 between the rear substrate 111 and the auxiliary bracket 2300.

The same may be applied to the case where the auxiliary bracket 2300 is not used and the bracket 140 includes a portion located on the side of the display panel 100.

Meanwhile, at least one of a gate driver for supplying a driving signal to the gate line and a data driver for supplying a driving signal to the data line may be mounted on the outer side of the rear substrate 111. The data driver 3910 includes a plurality of source drive ICs. Gate driver 3900 includes a plurality of gate drive ICs.

For example, as in the case of FIG. 39, the gate driver 3900 and the data driver 3910 may be formed on the rear substrate 111, respectively. Here, the gate driver 3900 and the data driver 3910 are formed on the rear substrate 111, respectively, so that the circuit elements necessary for driving the gate driver 3900 and the circuit elements necessary for driving the data driver 3910 are rear surfaces. It may mean that the substrate 111 is directly patterned through a semiconductor manufacturing process.

The gate driver 3900 and the data driver 3910 may be formed on the rear substrate 111 in the dummy area DA outside the screen area AA where an image is displayed.

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

Referring to FIG. 40, when the long side LS and the short side SS of the front substrate 101 extend longer than the long side LS and the short side SS of the rear substrate 111, the gate driver 3900 and the gate driver 3900. The data driver 3910 may be formed in an area OVA common to the front substrate 101 and the rear substrate 111.

The transistor 103 formed on the rear substrate 111, that is, a thin film transistor (TFT) for turning on / off liquid crystals for each pixel, is called a first transistor unit 103, and When the transistor included in the gate driver 3900 or the data driver 3910 formed in the region OVA common to the front substrate 101 and the rear substrate 111 overlaps with the outside, the first transistor is a first transistor. The unit 103 is disposed inside the seal unit 200, and the second transistor unit is disposed in an area OVA that overlaps the front substrate 101 and the rear substrate 111 at the outside of the seal unit 200.

For example, as shown in FIG. 41, the first gate driver 3900A is disposed in an area where the rear substrate 111 and the front substrate 101 overlap with each other at the first short side SS1 of the rear substrate 111. The second gate driver 3900B may be disposed in an area where the rear substrate 111 and the front substrate 101 overlap with each other at the second short side SS2 of the rear substrate 111.

In this case, the first length S1 can be substantially the same as the second length S2.

In addition, as shown in FIG. 42, the data driver 3910 may be disposed in an area where the rear substrate 111 and the front substrate 101 overlap on the second long side LS2 of the rear substrate 111. . In addition, the data driver may not be disposed in an area where the rear substrate 111 and the front substrate 101 overlap at the first long side LS1 of the rear substrate 111.

In this case, the twentieth length S20 may be larger than the tenth length S10.

In this case, as shown in FIG. 43, the rear substrate 111 and the front substrate 101 of the outer portion of the seal portion 200 overlap with each other at the second long side LS2 of the front substrate 101 and the rear substrate 111. The pad electrode 4300 may be formed in the region.

Here, the pad electrode 4300 may be used for electrical connection of the driving board 1900 for supplying a driving signal to a predetermined transistor.

For example, a driving board 1900 for supplying a driving signal to the display panel 100 is formed outside the display panel 100, for example, between the frame 1600 and the back cover 130 as in the case of FIG. 19. Can be placed in.

In this case, a connector 4310 is disposed on the driving board 1900, one end of the connection board 4320 including the electrode 4330 is connected to the connector 4310, and the other end of the connection board 4320 is connected to the driving board 1900. The pad electrode 4300 may be connected to the pad electrode 4300. Accordingly, the driving board 1900 and the pad electrode 4300, in detail, the driving board 1900 and the data driver 3910 may be electrically connected to each other.

The connection substrate 4320 may be a flexible substrate such as a tape carrier package (TCP), a flexible printed circuit (FPC), or the like.

As described above, the connection substrate 4320 may be connected to the pad electrode 4300 at the portion where the pad electrode 4300 is formed, and the front substrate 101 may not be visible from the front of the display panel. ) Can be extended longer than the rear substrate 111. That is, when the pad electrode 4300 is formed on the second long side LS2 of the rear substrate 111, the twentieth length S20 may be larger than the tenth length S10.

Referring to FIG. 44, the first pad electrode 4300A and the second pad electrode 4300B may be formed on the second long side LS2 side of the rear substrate 111 on the outer side of the seal portion 200.

The first connecting substrate 4320A may be electrically connected to the first pad electrode 4300A, and the second connecting substrate 4320B may be electrically connected to the second pad electrode 4300B.

In addition, a first transmission between the first pad electrode 4300A and the gate driver 3900 for transmitting a driving signal transmitted from the driving board (not shown) through the first connection board 4320A to the gate driver 3900. Line 4400 may be formed.

In addition, a second transmission between the second pad electrode 4300B and the data driver 3910 for transmitting a driving signal transmitted from the driving board (not shown) through the second connection board 4320B to the data driver 3910. Line 4410 may be formed.

Referring to FIG. 45A, the seal part 200 disposed between the front substrate 101 and the rear substrate 111 may be formed in the dummy area DA outside the screen area AA displaying an image. Accordingly, the seal 200 may overlap the blocking unit 1500.

In addition, the screen area AA may be formed in an area overlapping the optical layer 110 disposed on the inner side IA of the bracket 140.

One side 23a of the support pin 23 is fixed to the bracket 140 through screwing, and the other side 23b extends down to surround the backlight unit 120. Accordingly, the backlight unit 120 is fixed by the elasticity of the support pin 23.

As such, when the support pin 23 is used, since the support plate 1600 used to support the backlight unit 120 can be omitted, the thickness of the module (collectively, the backlight unit and the optical layer) can be reduced. have.

Next, referring to FIG. 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, and a back cover. It is comprised, including 69.

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

The first bracket 63 supports the panel 61 and accommodates the optical layer 65 and the backlight unit 67 therein. The first bracket 63 has a “c” shape with an open bottom to support three places of the liquid crystal panel 61. A recess is formed in the inner inner wall of the first bracket 63 so that the panel 61 can be supported.

The optical layer 65 and the backlight unit 67 are sequentially stacked behind the panel 61 with the first bracket 63 interposed therebetween.

And, the second bracket 64 is disposed below the module.

FIG. 58 is a cross-sectional view taken along the line X-X 'of FIG. 57 and shows a bottom engagement view of the device including the second bracket 64.

In FIG. 58, the second bracket 64 is located under the module to form the device. The second bracket 64 is preferably positioned in close contact with the panel 61 under the module, and the second bracket 64 and the surface of the panel 61 are preferably arranged on the same line. As described above, when the second bracket 64 is positioned on the same line as the surface of the panel 61, the panel 61 is enlarged by removing the boundary between the second bracket 64 and the panel 61. It is also possible to increase the design of the device.

In addition, an electrode 7100 for detecting a change in capacitance may be further formed on an inner surface of one end of the panel 61. The electrode 7100 is made of a transparent conductive material and may be configured in the form of a lattice-shaped diamond cell. When the user indirectly touches the electrode 7100 with the panel 61 interposed therebetween, the value of the capacitance is changed at the touched point, which is transmitted to the controller 7140 to correspond to the row of the touched electrode grid. The position of the touch is determined by reading the coordinates of the line. Accordingly, the controller can control the operation of the device by generating a control signal corresponding to the touched position. According to an embodiment, the controller 7140 may control operations such as up / down of the volume of the device or up / down of the channel according to the touched position.

In addition, in order to increase the touch sensitivity of the electrode 7100, one end of the panel 61 may include only one of the upper substrate and the lower substrate, and the electrode may be formed on the rear surface of the remaining substrate.

On the other hand, the second bracket 64 has the same configuration as the control unit 7140, the speaker 71, and the remote control receiving module (not shown) connected through the electrode 7100, which is the touch sensor described above, and the signal line 7110. Elements can be arranged, and by hiding the functional module inside the second bracket 64, space utilization can be increased in a slim structure.

The second bracket 64 may be fixed to the back cover 69 by screwing with the back cover 69, and as shown in FIG. 60, the first bracket 63 may have a side surface of the second bracket 64. In the extended state to 641, the side of the first bracket 63 may be fixed with an adhesive, or may be fixed through screwing, or may be coupled to both the first bracket 63 and the back cover 69.

Meanwhile, FIG. 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. In FIG. 60, the protrusion 641 is elongated along the longitudinal direction of the second bracket 64, and accordingly, the protrusion 641 is disposed thereon while surrounding the bottom of the panel 61. In this case, the protrusion 641 may be disposed to cover only the non-display area of the panel. As such, the protrusion 641 surrounds the end portion of the structurally fragile panel 61 to protect the panel 61, and also prevents contaminants such as dust from entering the device.

61 to 63 are views 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 substrate. The substrate 6110 may be formed of a metal (METAL) PCB made of a metal such as aluminum in which the insulating layer does not flow 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. The light emitting diode 6120 is preferably a side view light emitting diode having a light emitting surface facing to the side. In addition, the light source 6120 emits at least one of three primary colors of colors such as red, blue, and green, or emits white.

A second layer 6130 is formed above the first layer 6110 to fill the light sources 6120, and the second layer 6130 transmits light emitted from the light source 6120. Assured that the light emitted from light source 6120 is evenly provided to the panel.

In addition, a reflective layer 6140 reflecting light emitted from the light source 6120 may be further formed between the first layer 6110 and the second layer 6130, that is, the upper surface of the first layer 6110. The reflective layer 6140 reflects the light totally reflected from the boundary surface of the second layer 6130 so that the light emitted from the light source 6120 is provided in a more diffused state.

As the reflective layer 6140, a white pigment such as titanium oxide is dispersed in a sheet made of a synthetic resin material, a metal deposition film is disposed on a surface thereof, or a bubble is dispersed in order to scatter light in a synthetic resin sheet. In addition, silver may be coated on the surface to increase the reflectance. The reflective layer 6140 may also be formed in a form coated on the first layer 6110. The second layer 6130 may be made of a light transmissive material, for example, silicone or acrylic resin.

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

The second layer 6130 may be formed by coating a resin in a liquid or gel state on top of the plurality of light sources 6120 and the first layer 6110 and curing the resin. It may be adhered to the upper portion of the first layer 6110 in a state.

As the thickness of the second layer 6130 increases, the light emitted from the light source 6120 diffuses more widely, so that light having a uniform brightness may 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 by the second layer 6130 increases, so that the brightness of the light may decrease.

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

Referring to FIG. 62, a form in which the side light emitting diode 6120 is disposed is illustrated.

These light emitting diodes 6120 emit light in the lateral direction. Thus, in order for the backlight unit 6100 to exhibit uniform brightness as a whole, the light emitting diodes 6120 may be disposed 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, light sources left and right adjacent to the first light source 6120 also emit light in the same direction as the first light source 6120 (the arrow direction in the drawing), and light sources adjacent to the left and right sides of the second light source 6121 are formed of the first light source 6120. 1 Light is emitted in a direction opposite to the light source 6120 (the direction opposite to the arrow in the drawing).

As such, since the light emitting diodes 6120 and 6121 emit light in opposite directions along the row, the phenomenon in which the luminance of the light is concentrated or weakened in a specific area of the backlight unit 6100 may be reduced.

The backlight unit 6100 formed as described above may be driven by a whole driving method or a partial driving method such as local dimming or impulsove.

That is, the backlight unit 6100 may be operated by being divided into a plurality of divided driving regions, and the display quality of an image such as contrast ratio and clarity may be improved by driving the luminance of the divided driving region according to the luminance of the image signal. In accordance with this, the backlight unit 6100 may also be formed in a plurality of combined forms. For example, the plurality of optical assemblies 6101 illustrated in FIG. 63 may be assembled to form one backlight unit 6100. In this case, only some of the optical assemblies 6101 may be driven independently to emit light, and for this purpose, the light sources 6120 included in the respective optical assemblies 6101 may be independently controlled.

Meanwhile, an area of the panel corresponding to one optical assembly 6101 may be divided into two or more blocks, and the panel and the backlight unit 6100 may be dividedly driven in blocks. As such, when the backlight unit 6100 is configured of the plurality of optical assemblies 6101, the manufacturing process of the backlight unit 6100 may be simplified, and the loss that may occur in the manufacturing process may be minimized. In addition, the backlight unit 6100 may be applied to backlight units of various sizes by standardizing and mass-producing the optical assembly 6101.

Furthermore, when a failure occurs in the light emitting diode provided in the backlight unit 6100, the replacement operation is easy because only the optical assembly 6101 is selectively replaced without the need to replace the entire backlight unit 6100. The cost of replacing parts can be reduced.

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.
