[ ) In the space between the two. In another aspect, the driving boards 200 and 210 may be exposed in a space between the adjacent vertical bars 120V.

This is because the plurality of the horizontal bars 120H are arranged apart from each other in the second direction DRV and the plurality of vertical bars 120V are arranged apart from each other in the first direction DRH, Lt; / RTI >

When the driving boards 200 and 210 are exposed in the space between adjacent frame bars 120 and the driving boards 200 and 210 and the frame bars 120 are disposed on the rear cover 130, (200, 210) can be repaired.

10, cables (cables 240 and 250) may be used to electrically connect the display panel 100 and the at least one drive board 200 and 210 to each other.

For example, as shown in FIG. 11, a predetermined connector 230 is disposed on the driving boards 200 and 210, and one end E1 of the cables 240 and 250 is connected to the connector 230 .

In addition, the connection part of the connector 230 and one end E1 of the cable 240 or 250 may be exposed to the space between adjacent frame bars 120. [

Referring to FIG. 12, each of the light source arrays 110B1, 110B2, and 110B3 may be disposed on the horizontal bar 120H.

For example, the first light source array 110B1 is disposed on the first horizontal bar 120H1, the second light source array 110B2 is disposed on the second horizontal bar 120H2, and the third light source array 110B3 And may be disposed on the third horizontal bar 120H3.

When the light source arrays 110B are disposed on the respective horizontal bars 120H, the number of the horizontal bars 120H and the number of the light source arrays 110B may be the same.

In addition, when the light source arrays 110B are disposed on the respective horizontal bars 120H, the interval between the adjacent horizontal bars 120H may be substantially the same.

For example, as in the case of FIG. 12, when the horizontal bar 120H includes the first, second, and third horizontal bars 120H1, 120H2, and 120H3 that are continuously disposed, the first horizontal bar 120H1 The distance D3 between the second horizontal bars 120H2 may be approximately the same as the distance D2 between the second horizontal bars 120H2 and the third horizontal bars 120H3.

Preferably, the distance D3 between the first horizontal bar 120H1 and the second horizontal bar 120H2 is greater than the distance D2 between the second horizontal bar 120H2 and the third horizontal bar 120H3, Lt; / RTI > Here, the error range may mean a range in which optical characteristics according to the position of the display panel 100 can be uniform. Such an error range may be, for example, 10 mm.

In addition, when the light source array 110B is disposed on each of the horizontal bars 120H, the interval between adjacent horizontal bars 120H may be smaller than the interval between adjacent vertical bars 120V.

For example, the interval D1 between the first vertical bar 120V1 and the second vertical bar 120V2 is set to be equal to the interval D3 between the first horizontal bar 120H1 and the second horizontal bar 120H2, May be greater than the distance D2 between the third horizontal bar 120H2 and the third horizontal bar 120H3.

In this case, since the interval between the adjacent light source arrays 110B can be made relatively small, the optical characteristics can be improved.

When the light source array 110B is disposed on at least one of the horizontal bars 120H as described above, the vertical bar 120V is disposed in the horizontal bar 120H because the light source array 110B is disposed toward the display panel 100. Thus, And the rear cover 130, as shown in FIG.

The adhesive layer 400 can fix the light source array 110B to the frame bar 120H and transmit heat generated from the light source array 110B to the frame bar 120H. To this end, it is also possible that the adhesive layer 400 includes a metal material having a relatively high thermal conductivity.

The light source array 110B may include a substrate 300 and a light source 310 disposed on the substrate 300. [ In this case, the adhesive layer 400 may be positioned between the substrate 300 and the frame bar 120.

It is also possible that the light source array 110B is disposed on at least one horizontal bar 120H and the light source array 110B is not disposed on at least one horizontal bar 120H.

For example, as in the case of Fig. 14, when the horizontal bar 120H includes the first, second, third, fourth and fifth horizontal bars 120H1, 120H2, 120H3, 120H4 and 120H5 arranged in succession, The first light source array 110B1 is disposed on the first horizontal bar 120H1 and the second light source array 110B2 is disposed on the third horizontal bar 120H3 and the third light source array 110B2 is disposed on the fifth horizontal bar 120H5. (110B3) can be disposed.

In this case, the distance between the horizontal bars 120H in which the light source arrays 110B are arranged, that is, the distance D5 between the first horizontal bar 120H1 and the third horizontal bar 120H3, And the interval D4 between the fifth horizontal bar 120H5 and the fifth horizontal bar 120H5.

The distance D1 between the first vertical bar 120V1 and the second vertical bar 120V2 is determined by the distance between the horizontal bars 120H in which the light source arrays 110B are disposed, The distance D5 between the third and fourth horizontal bars 120H3 and 120H3 and the distance D4 between the third and fifth horizontal bars 120H3 and 120H5.

Alternatively, the light source array 110B may be disposed on the vertical bar 120V.

For example, as in the case of Fig. 15, when the vertical bar 120V includes the first, second and third vertical bars 120V1, 120V2 and 120V3 arranged continuously, the first vertical bar 120V1 It is possible that the first light source array 110B1 is arranged and the second vertical bar 120V2 is arranged with the second light source array 110B2 and the third vertical bar 120V3 is arranged with the third light source array 110B3 Do.

In this case, the distance between the vertical bars 120V in which the light source arrays 110B are arranged, that is, the distance D6 between the first vertical bar 120V1 and the second vertical bar 120V2, And the interval D7 between the third vertical bars 120V3.

In this way, when the light source array 110B is disposed on at least one vertical bar 120V, the horizontal bar 120H can be positioned between the vertical bar 120V and the rear cover 130.

A reflective layer 500 may be disposed between the optical layer 110A and the rear cover 130, as in the case of FIG.

The reflective layer 500 may reflect incident light to improve optical characteristics. The reflective layer 500 may include a material having high reflectance.

For example, as in the case of FIG. 18, the reflective layer 500 may be possible to include a base substrate 530, a coating surface 520 coated on the base substrate 530, and the like. Here, the coating surface 520 may include a metal material having a high reflectance such as aluminum (Al) or silver (Ag).

Here, it is assumed that the reflective layer 500 is composed of two layers, but the present invention is not limited thereto. For example, the reflective layer 500 may be composed of a single layer.

Meanwhile, the reflective layer 500 may be connected to the frame bar 120. For this purpose, protrusions may be formed on the frame bar 120 and holes corresponding to the protrusions may be formed on the reflective layer 500.

For example, as in the case of FIG. 19, at least one end portion of the horizontal bar 120H, preferably a protrusion 120P projecting toward the display panel 100, may be formed at both ends have.

In addition, the reflective layer 500 may include a fixing hole 540 corresponding to the protrusion 120P.

20, the reflection layer 500 may be connected to the horizontal bar 120 such that the protrusion 120P is inserted into the fixing hole 540. In this case,

The reflective layer 500 may be connected to the horizontal bar 120H in a state in which the light source 310 is exposed through the light source hole 510. [
