Here, a region where the cover bottom 110 and the lower guide panel 142 are fastened is covered by a side surface of the upper guide panel 141 .

More specifically, as shown in FIG. 3 , at least one bottom hook 111 is provided on the side surface of the cover bottom 110 .

The bottom hook 111 may be formed by punching the side surface of the cover bottom 110 .

In this case, the bottom hook 111 protrudes from the inner space of the cover bottom 110 toward the outer space of the cover bottom 110 .

At least one bottom hook hole 142a to which the bottom hook 111 is fastened is provided on a side surface of the lower guide panel 142 .

The bottom hook hole 142a may pass through a side surface of the lower guide panel 142 .

The protruding size of the bottom hook 111 may be greater than the thickness of the side surface of the cover bottom 110 .

Recently, in order to reduce the weight and thickness of the liquid crystal display module and the liquid crystal display device, a cover bottom made of a light and thin material is used.

Therefore, when the bottom hook 111 having a larger protrusion amount than the thickness of the side surface of the cover bottom 110 is formed on the side surface of the cover bottom 110 made of a very thin material, as shown in FIG. Similarly, a separation space may be generated between the bottom hook 111 and the cover bottom 110 . The separation space may be formed in the form of a slit.

The separation space may face the light guide plate 120 . In this case, the light output from the light guide plate 120 may flow outward of the cover bottom 110 through the separation space as shown in FIG. 3 .

The lower guide panel 142 is also formed of a thin material. The bottom hook 111 should be mounted in the bottom hook hole 142a. The protruding size of the bottom hook 111 may be greater than the thickness of the side surface of the cover bottom 110 . Accordingly, the thickness of the bottom hook hole 142a should also be greater than the thickness of the side surface of the cover bottom 110 .

Accordingly, the bottom hook hole 142a may pass through the lower guide panel 142 .

In this case, the light output from the light guide plate 120 may flow outward of the cover bottom 110 through the separation space of the bottom hook 111 , and may flow outward of the cover bottom 110 . The light leaked out through the bottom hook hole 142a may flow out of the lower guide panel 142 through the bottom hook hole 142a.

The light leaked to the outside of the lower guide panel 142 can be seen by the user's eyes by leaking out through the rear cover 200 or the front cover.

In order to prevent this phenomenon, in the present invention, a region where the cover bottom 110 and the lower guide panel 142 are fastened is covered by the side surface of the upper guide panel 141 .

In detail, the bottom hook 111 may be provided by protruding a side surface of the cover bottom 110 , and a slit through which light passes may be provided in the bottom hook 111 , and the bottom hook 111 may be provided with a slit through which light passes. The hook hole 142a may pass through the side surface of the lower guide panel 142 . In this case, the bottom hook hole 142a is covered by the side surface of the upper guide panel 141 . Accordingly, the light emitted through the slit and the bottom hook hole 142a does not flow out of the liquid crystal display module 100 .

4 is a perspective view showing a corner of a liquid crystal display module according to the present invention.

As described above, the liquid crystal display module 100 according to the present invention includes a liquid crystal panel 150 , the light source unit 125 , the light guide plate 120 , the cover bottom 110 , and the lower guide panel 142 . ) and the upper guide panel 141 .

At least one bottom hook 111 is provided on the side surface of the cover bottom 110 , and at least one bottom hook hole 142a through which the bottom hook 111 is fastened is provided on the side surface of the lower guide panel 142 . provided

The protruding size of the bottom hook 111 may be greater than the thickness of the side surface of the cover bottom 110 . For example, the bottom hook 111 may be provided by protruding a side surface of the cover bottom 110 .

The bottom hook hole 142a may pass through a side surface of the lower guide panel 142 .

The bottom hook 111 may be provided with a slit through which light passes. The slit is not intended by the manufacturer. In more detail, since the thickness of the side surface of the cover bottom 110 is thin, when the bottom hook 111 is formed, the slit may be formed regardless of the intention of the manufacturer.

In the present invention, in order to prevent the light output from the light guide plate 120 or the light source unit 125 through the slit from leaking out through the bottom hook hole 142a, as shown in FIG. , the bottom hook hole 142a is covered by the side surface of the upper guide panel 141 .

For example, in FIG. 4 , since the bottom hook hole 142a and the bottom hook 111 are covered by the upper guide panel 141 , the bottom hook hole 142a and the bottom hook 111 are covered. ) is indicated by a dotted line.

At least one lower hook 142b is provided on the side surface of the lower guide panel 142 as shown in FIG. 4 .

In this case, at least one lower hook hole 141a into which the lower hook 142b is inserted is provided on a side surface of the upper guide panel 141 .

The lower hook 142b provided on the side of the lower guide panel 142 is inserted and fixed into the lower hook hole 141a provided on the side of the upper guide panel 141, so that the lower guide panel ( 142) and the upper guide panel 141 may be coupled to each other.

The lower hook 142b may be formed by punching the side surface of the lower guide panel 142 . Accordingly, the lower hook 142b protrudes outwardly of the lower guide panel 142 .

The lower hook hole 141a may pass through the side surface of the upper guide panel 141 .

A structure similar to the slit formed in the bottom hook 111 may be formed in the lower hook 142b as well.

However, a region of the lower guide panel 142 in which the lower hook 142b is formed is covered by the cover bottom 110 . Therefore, light does not flow out to the lower hook 142b.

In more detail, since light can leak through the bottom hook 111 , the bottom hook hole 142a to which the bottom hook 111 is fastened is covered by the upper guide panel 141 .

However, since light does not flow through the lower hook 142b, even if the lower hook hole 141a is formed in the upper guide panel 141, the lower hook hole ( 141a) does not leak light.

The present invention described above is briefly summarized as follows.

In the present invention, light leakage can be prevented by using the double guide panel 140 .

The guide panel 140 includes the lower guide panel 142 fastened to the cover bottom 110 and the upper guide panel 141 fastened to the lower guide panel 142 .

For fastening with the cover bottom 110 , a bottom hook hole 142a may be formed in a side surface of the lower guide panel 142 , and the bottom hook hole 142a is formed of the upper guide panel 141 . covered by the sides. Accordingly, the light leaked into the bottom hook hole 142a through the bottom hook 111 is blocked by the upper guide panel 141 .

Accordingly, light is not leaked from the inside of the liquid crystal display module 100 to the outside.

According to the present invention, since the bottom hook hole 142a passing through the side surface of the lower guide panel 142 is formed on the side surface of the lower guide panel 142, the amount of protrusion of the bottom hook 111 is can be secured.

Accordingly, the fastening force between the bottom hook hole 142a and the bottom hook 111 may be increased, and accordingly, the stability of the liquid crystal display module may be improved.

In addition, since the bottom hook hole 142a is covered by the side surface of the upper guide panel 141, light leakage defects can be prevented without additional cost.

Those skilled in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential characteristics thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the following claims rather than the above detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention. do.
