Part or all of the second support part 120b is inserted into the mold frame 110.

Referring to the method of forming the chassis 120 and the mold frame 110, after the chassis 120 is formed first, the chassis 120 is disposed in a mold frame, the mold frame ( Inject the casting to form 110).

In this case, the casting may be cured, and the mold frame 110 may be formed such that a part or all of the second support part 120b is inserted into the mold frame 110.

The second support part 120b includes a third frame 121, a fourth frame 122, a fifth frame 123, and a sixth frame 124.

The third to sixth frames 121, 122, 123, and 124 extend from the first support part 120a. In addition, the third to sixth frames 121, 122, 123, and 124 are spaced apart from each other and have a curl shape.

The height H1 of the third frame 121 is lower than the height H2 of the fourth to sixth frames 122, 123, and 124.

In addition, a portion 121a of the third frame 121 is exposed on the upper surface of the mold frame 110 and is disposed on the upper surface of the mold frame 110. In more detail, the upper portion 121a of the third frame 121 is exposed on the upper surface of the second frame 112 and is disposed on the second frame 112.

At this time, the upper surface of the exposed third frame 121 is formed as a curved surface.

The backlight assembly 200 is disposed inside the accommodating device 100. The backlight assembly 200 generates light and exits upward. The backlight assembly 200 includes a reflective sheet 210, a light guide plate 220, a light emitting diode 230, and an optical sheet 240.

The reflective sheet 210 is disposed on the first support part 120a. The reflective sheet 210 reflects light generated from the light emitting diode 230 upwards.

The light guide plate 220 is disposed on the reflective sheet 210. The light guide plate 220 emits light emitted from the light emitting diode 230 upwards through refraction, scattering, and reflection.

The light emitting diode 230 is disposed on the side surface of the light guide plate 220 and is disposed inside the receiving groove 113. The light emitting diode 230 generates light and emits the light toward the side surface of the light guide plate 220.

The optical sheet 240 is disposed on the light guide plate 220. The optical sheet 240 improves the characteristics of the light passing through. The optical sheet 240 may be a diffusion sheet or a prism sheet.

The flexible circuit board 231 is electrically connected to the light emitting diodes 230. Power is supplied to the light emitting diodes 230 through the flexible circuit board 231. The flexible circuit board 231 is flexible.

The light emitting diodes 230 are mounted on the flexible circuit board 231. The flexible circuit board 231 is disposed on the mold frame 110. In more detail, the flexible circuit board 231 is disposed on the second frame 112.

In addition, the flexible circuit board 231 is disposed on the third frame 121. In more detail, the flexible circuit board 231 is disposed on an upper surface of the exposed third frame 121.

Since the upper surface of the exposed third frame 121 forms a curved surface, the flexible circuit board 231 is curved to correspond to the upper surface of the third frame 121.

That is, the flexible circuit board 231 is curved to form a curved surface corresponding to the third frame 121. In addition, the flexible circuit board 231 contacts the third frame 121 and is bent to form a curved surface.

The liquid crystal panel 300 is disposed on the optical sheet 240. The liquid crystal panel 300 is disposed inside the accommodating device 100. In addition, the liquid crystal panel 300 is disposed on the second frame 112.

In addition, the liquid crystal display may include a connection substrate 320 electrically connected to the liquid crystal panel 300.

Since the second support part 120b has a curved surface, the second support part 120b has an improved strength. More specifically, since the third to sixth frames 121, 122, 123, and 124 have a curl shape and a shape that curls inwardly of the chassis 120, the third to sixth frames 121, 122, 123, and 124 have an improved strength.

In particular, the third to sixth frames 121, 122, 123, and 124 are less curved than when flat. That is, the accommodating device 100 is less bent to a stronger force.

Thus, the liquid crystal display according to the embodiment has a more improved strength.

In addition, since the flexible circuit board 231 is bent corresponding to the upper surface of the third frame 121 which is a curved surface, the flexible circuit board 231 is bent less rapidly.

That is, since the flexible printed circuit board 231 is less bent than when the third frame 121 has a bent shape, the flexible circuit board 231 applies a smaller force to the light emitting diode 230.

That is, the liquid crystal display according to the embodiment may reduce the elastic force generated by the bending of the flexible circuit board 231.

Accordingly, the liquid crystal display according to the embodiment prevents the emission direction of the light emitting diode 230 from being disturbed by bending the flexible circuit board 231 and improves the brightness uniformity of the backlight assembly 200. Can be.

Accordingly, the liquid crystal display according to the embodiment may have more improved intensity and more improved image quality.
