The closed four side walls 82 cooperate with the bottom plate 84 to form a generally rectangular space having an opening (not shown). The volume of the space is substantially the same as the volume of the liquid crystal display module 20. The side wall 82 extends an extension into the semi-closed space at a distance from the bottom plate 84. The extension 83 is perpendicular to the side wall 82 and has a "back" shape. If the size of the liquid crystal display device 2 is larger, the bottom plate 84 may be a metal member, the material of the side wall 82 may be plastic, and the side wall 82 and the bottom plate 84 may be integrally formed by in-mold forming technology.

The backlight module 23 includes a plurality of optical films 24, a light guide plate 26, a strip-shaped lamp tube 25, and a reflection sheet 27. The thickness of the light guide plate 26 and the reflection sheet 27 is substantially the same as the distance from the extension portion 83 to the bottom plate 84. The thickness of the optical film 24 is slightly smaller than the thickness of the extension portion 83. The light guide plate 26 includes a light incident surface 261, a light exit surface 263 adjacent to the light incident surface 261, and a bottom surface 265 opposite to the light exit surface 263. 3 and FIG. 4, FIG. 3 is a partial assembly view of the liquid crystal display device 2 shown in FIG. 2, and FIG. 4 is a schematic cross-sectional view taken along line IV-1V of FIG. The external force is applied to elastically deform the four side walls 82, and the space is slightly increased. Therefore, even if there is a barrier of the extension portion 83, the reflection sheet 27, the light guide plate 26, and the strip lamp tube 25 can be assembled into the extension portion 83. · Inside. The reflective sheet 27 is disposed on the bottom plate 84. The bottom surface 263 of the light guide plate 26 is disposed adjacent to the reflective sheet 27. The strip light tube 25 is disposed on the side of the light incident surface 261 of the light guide plate 26, and the optical film 098137672 is in the form number. Α0101 Page 5 of 15 page 0982064556-0 201116885 The sheet 24 is disposed on the light-emitting surface 263 side of the light guide plate 26, and the edge of the optical film 24 is in contact with the edge of the extending portion 83, and the liquid crystal panel 21 is disposed at the side The outer side of the extending portion 83 is supported by the extending portion 83, and the light shielding tape 29 is attached to the top of the side wall 82 and the edge of the liquid crystal panel 21 to fix the liquid crystal panel 21. The front case 40 and the rear case 80 together receive and fix the liquid crystal display module 20, and the light shielding tape 29 is adjacent to the front case 40. [0013] Compared with the prior art, the present invention omits the use of the front iron frame by shading. Instead of fixing the liquid crystal panel, the tape is used to replace the rear iron frame and the plastic frame by providing a sidewall structure on the rear case, thereby effectively reducing the number of components of the liquid crystal display device and reducing the raw materials and the original function. Manufacturing costs, reduced product weight, and reduced product thinness and volume. Referring to Fig. 5, there is shown a perspective exploded view of a second embodiment of the liquid crystal display device of the present invention. The second embodiment of the present invention is basically the same as the first embodiment, except that the <side of the light guide plate 36 of the liquid crystal display device 3 has a plurality of convex first card corners 367, and one side of the optical film 34 has a plurality of protruding second corners 347, the extending portion 383 of the rear case 380 has a plurality of notches 387 corresponding to the first card corner 367 of the light guide plate 36 and the second card angle 347 of the optical film 34. The plurality of notches 387 can pass the plurality of first corners 367 of the light guide plate 36 to allow the light guide plate 36 to enter, and the plurality of notches 387 receive the second card corners 347 of the optical film 34. Positioning the optical film 34 in the housing relationship prevents the light guide plate 36 from being assembled incorrectly. [0015] In another embodiment of the present invention, for example, a reflective layer is disposed on the side wall of the semi-closed side and the inner side of the bottom plate, thereby omitting the reflection sheet, and the bottom wall extends a bottom portion into the space, and the top of the bottom platform supports the liquid crystal panel, and the bottom of the bottom platform is The inside of the bottom plate 098137672 Form No. A0101 Page 6 / Total 15 page 0992064556-0 201116885 Ο [0016] [0019] [0020] [0020] [0021] 098137672 connected, at this time, the space is slightly smaller, the light guide plate volume Also slightly smaller, the thickness of the light guide plate is substantially the same as the distance from the extension to the bottom plate. The base has a square hole, and the size of the hole corresponds to the first card angle of the light guide plate and the second card angle of the optical film. When assembled, the sidewall can receive the light guide plate without being deformed, and the cutout hole accommodates the first card angle of the light guide plate and the second card angle of the optical film. For another example, the extension portion may be two extension strips extending in the middle of the side wall, and the positions of the two extension strips may be oppositely disposed or adjacently disposed. The extension may be three "Π" shaped extension strips extending in the middle of the side wall. In addition, the four side walls may be connected to each other without head and tail. The liquid crystal panel can be tempered glass to increase the strength and prevent damage due to the absence of the front iron frame.
