The optical layer 130 may include a diffusion sheet 131, a prism sheet 132, and a light guide plate 133. Here, the case where the optical layer 130 includes three functional layers is described, but the structure of the optical layer 130 may be variously changed. For example, the light guide plate 133 in the optical layer 130 may be omitted.

When the optical waveguide 133 is included in the optical layer 130, a light source such as a light emitting diode (LED), not shown, may be positioned on the side surface of the light guide plate 133. A backlight unit having such a configuration can be referred to as an edge type backlight unit.

If the light guide plate 133 is omitted in the optical layer 130, the light source may be positioned behind the display panel 100. [ The backlight unit having such a configuration can be called a direct type.

The configuration of the backlight unit in the display device 10 according to the present invention can be variously changed.

4 and 5, the frame 140 includes a first part 200, a second part 210, and a second part 210. The first part 200 is positioned between the first part 200 and the second part 210, (Third Part) 220, which is shown in FIG.

Figs. 4 and 5 show the internal surface of the frame 140. Fig. Here, the inner surface of the frame 140 may be a surface facing the optical layer 130 (not shown).

The third portion 220 may be formed by recessing a part of the frame.

In other words, a hollow may be formed between the first portion 200 and the second portion 210.

Here, the third portion 220 may be configured to surround at least three sides of the second portion 210. In this case, it is possible to further improve the rigidity of the frame 140.

The frame 140 may further include a fourth portion 230. The fourth portion 230 may also be formed by recessing a part of the frame 140.

In the frame 1000, the second portion 210, the third portion 220, and the fourth portion 230 may be formed by a forming method or the like.

The fourth portion 230 may be adjacent to the first, second, and third portions 200, 210, 220, respectively.

For example, the fourth portion 230 may be formed in the second long side (LS2) region of the frame 140.

In addition, the first portion 200 may form the first long side LS1, the first short side SS1, and the second short side SS2 of the frame 140. Accordingly, it is possible for the first portion 200 and the fourth portion 230 to surround the second portion 210 and the third portion 220.

A light source or the like may be disposed in the fourth portion 230, though not shown. The width X2 of the fourth portion 230 in the second direction DR2 is larger than the width X1 of the third portion 220 in the first direction DR1 or the second direction DR2 .

A side wall 140V extending in a vertical direction (third direction DR3) may be formed at an edge of the first portion 200. [

A driving board 160 may be disposed behind the second portion 210 of the frame 140 as shown in Figure 6 when the frame 140 is cut along the line A1-A2 have. The lines A1-A2 are aligned with the short sides SS1 and SS2 of the frame 140 and parallel to the first portion 200, the third portion 220, and the second portion DR2 of the frame 140 in the second direction DR2 210 and the fourth portion 230. [

Referring to FIG. 6, the second portion 210 of the frame 140 may be located at a lower position than the first portion 200. In other words, the distance between the second portion 210 and the display panel 100 in the vertical direction (the third direction DR3) may be greater than the distance between the first portion 200 and the display panel 100 .

In addition, the interval between the third portion 220 and the display panel 100 in the vertical direction (third direction DR3) may be larger than the interval between the second portion 210 and the display panel 100. [

The distance D1 between the second portion 210 and the optical layer 130 in the vertical direction (the third direction DR3) is smaller than the distance D1 between the second portion 210 and the optical layer 130, 1 portion 200 and the optical layer 130, as shown in FIG. The interval D2 between the third portion 220 and the optical layer 130 in the vertical direction (the third direction DR3) is the distance D1 between the second portion 210 and the display panel 100, .

As such, in the structure in which the third portion 220 further protrudes rearward than the second portion 210, the rear cover 150 can be more easily connected to the third portion 220. In addition, the driving board 160 disposed in the second portion 210 can be more easily protected.

The interval between the fourth portion 230 and the display panel 100 in the vertical direction (the third direction DR3) may be larger than the interval between the first portion 200 and the display panel 100. [ In other words, the distance D3 between the fourth portion 230 and the optical layer 130 in the vertical direction (the third direction DR3) is smaller than the distance between the first portion 200 and the optical layer 130 It can be big.

Alternatively, the interval between the fourth portion 230 and the display panel 100 in the vertical direction (the third direction DR3) may be smaller than the interval between the third portion 220 and the display panel 100. [ In other words, the distance D3 between the fourth portion 230 and the optical layer 130 in the vertical direction (the third direction DR3) is smaller than the distance D3 between the third portion 220 and the optical layer 130 D2).

The optical layer 130 may be disposed in the first portion 200 of the frame 140. Here, although the optical layer 130 is illustrated as being in close contact with the first portion 200 of the frame 140, the optical layer 130 and the first portion 200 may be spaced apart from each other by a predetermined distance.

As such, as the optical layer 130 is positioned adjacent the first portion 200 of the frame 140, a sufficiently large air layer (not shown) is formed between the optical layer 130 and the second portion 210 of the frame 140 An air gap may be formed.

In this case, heat generated during driving of the driving board 160 can be prevented from being transmitted to the optical layer 130. Thus, thermal deformation of the optical layer 130 can be suppressed.

7, the fourth portion 230 of the frame 140 may be adjacent to the first portion 200, as shown in FIG. 7, in which the frame 140 is cut along the line A3-A4. The line A3-A4 is aligned with the short sides SS1 and SS2 of the frame 140 and passes through the first portion 200 and the fourth portion 230 of the frame 140 in the second direction DR2, Portion 210 and the third portion 220 of FIG.

In addition, the frame 140 may include protrusions 400 formed on the side wall 140V and protruding in the horizontal direction (the first direction DR1 and / or the second direction DR2). The protrusion 400 may be formed by a method of processing the side wall 140V of the frame 140 by a method such as forming. The protrusion 400 can be regarded as a portion where the side wall 140V of the frame 140 protrudes in the horizontal direction (the first direction DR1 and / or the second direction DR2).

The guide panel 120 may have a first groove 124 corresponding to the extension 140S of the frame 140 and a second groove 410 corresponding to the projection 400. [
