More specifically, the case top 180 protects the flexible film 151 and is fastened to the guide panel 140 to dissipate heat generated from the driver IC 153 to the outside.

Accordingly, the case top 180 is disposed in an area where the flexible film 151 is disposed. For example, as shown in FIGS. 5 and 7 , the flexible film 151 is disposed on the first side among the four side surfaces of the liquid crystal display device. The first side surface means a side surface disposed in a direction indicated by E in FIG. 5 .

In this case, the case top 180 is also disposed on the first side surface.

More specifically, the case top 180 is fastened to the guide panel 140 constituting the backlight unit 190 in the first lateral direction E where the flexible film 151 is disposed. and covers the flexible film 151. In particular, the case top 180 is fastened to the guide panel 140 using the top hook part 181 .

To this end, the guide panel 140 is provided with a guide hook part 142 coupled to the top hook part 181 .

As shown in FIG. 7 , the top hook part 181 is disposed on the inner surface of the front of the case top 180, and the guide hook part 142 is disposed on the outer surface of the front of the guide panel 140. are placed Here, as shown in FIG. 7 , the inner surface of the front of the case top 180 means a surface adjacent to the guide panel 140 among the front surfaces of the case top 180 . In addition, the outer surface of the front of the guide panel 140 refers to a surface of the front surface of the guide panel 140 adjacent to the case top 180 .

In this case, if the top hook part 181 is a groove having a shape recessed from the inner surface of the front surface of the case top 180, the guide hook part 142 is the outer surface of the front surface of the guide panel 140 It can be a hook protruding from the

In addition, if the module hook part 141 is a hook protruding from the outer surface of the side surface of the guide panel 140, the rear hook part 210 is a groove having a shape recessed from the inner surface of the side surface of the rear cover can be

In addition, if the top hook part 181 is a hook protruding from the inner surface of the front surface of the case top 180, as shown in FIG. It may be a groove having a shape recessed from the outer surface of the front face.

By the top hook part 181 and the guide hook part 142, the guide panel 140 and the case top 180 can be easily fastened.

In this case, the front cover 300, among the side surfaces of the liquid crystal display module 100, is directed toward the first side surface on which the flexible film 151 constituting the liquid crystal display module 100 is disposed (E). ), and covers the outer periphery of the front of the liquid crystal display module 100.

The front cover 300 serves to cover the flexible film 151 exposed between the liquid crystal panel 150 and the guide panel 140 . For example, if the front cover 300 is not present, in FIG. 7 , the flexible film 151 is exposed between the liquid crystal panel 150 and the guide panel 140 . However, since the front cover 300 covers the area adjacent to the liquid crystal panel 150 and the guide panel 140, the flexible film 151 is not exposed to the outside, and thus the flexible film (151) can be protected.

In this case, the front width S1 of the case top 180 is smaller than the front width S2 of the guide panel 140 . Also, the front width S2 of the guide panel 140 is smaller than the front width S3 of the front cover 300 .

For example, as shown in FIGS. 5 and 7 , in the first side direction E of the liquid crystal display, the case top 180, the guide panel 140 and the front cover 300 are overlapped. In this case, the width S2 of the guide panel 140 is greater than the width S1 of the case top 180, and the width of the front cover 300 is greater than the width S2 of the guide panel 140. (S3) is larger.

According to the present invention as described above, the case top 180 does not cover the front surface of the liquid crystal panel 150 . Therefore, compared to the liquid crystal display module and liquid crystal display device in which the case top covers the front surface of the liquid crystal panel, the thickness of the area where the case top 180 is disposed is approximately It can be reduced by 1.2 mm.

To elaborate, in FIG. 7 , the thickness of the front surface of the case top 180 affects the overall thickness of the liquid crystal display module 100 and the liquid crystal display device. In particular, in FIG. 7 , the thickness of the liquid crystal display module 100 has nothing to do with the thickness of the front surface of the case top 180, and the thickness of the liquid crystal display device includes the thickness of the liquid crystal display module 100, It is determined according to the thickness of the rear cover 200 and the thickness of the front cover 300 .

According to the present invention as described above, there is no possibility of an issue due to deformation of the case top 190. In addition, since the shape of the case top 190 can be simplified, manufacturing costs can be reduced.

By fastening the front cover 300 and the rear cover 200, the liquid crystal display module 100, the front cover 300, and the rear cover 300 may be integrally fastened.

In this case, as described above, the liquid crystal display module 100 and the rear cover 300 are fastened by the module hook part 141 and the rear hook part 210, as shown in FIG. do.

The rear cover 200 and the front cover 300 may be fastened with hooks or bolts. In particular, the rear cover 200 and the front cover 300, as shown in FIG. 7, the front hook portion 310 provided on the front cover 300 and the rear cover 200 It can be fastened by the provided rear cover hook part 220 .

As shown in FIG. 7, the front hook part 310 and the rear cover hook part 220 may be provided on the first side surface, or a second side surface adjacent to the first side surface And it may be provided on the third side. In addition, the front hook part 310 and the rear cover hook part 220 may be provided in the rear direction of the rear cover 200 .

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 its technical spirit or essential features. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting. The scope of the present invention is indicated by the following claims rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be construed as being included in the scope of the present invention. do.
