More specifically, the liquid crystal panel and the diffuser plate may both be seated and integrally fixed to the reflective sheet. The present invention relates to a formed mold and a liquid crystal display including the same.

Liquid crystal display (LCD) is one of the most widely used flat panel display (FPD), and consists of two substrates on which electrodes are formed and a liquid crystal layer interposed therebetween. A display device adjusts the amount of light transmitted by rearranging liquid crystal molecules of a liquid crystal layer by applying a voltage to an electrode.

The liquid crystal display device requires a plurality of elements such as a liquid crystal panel, a diffusion plate, and a reflective sheet, and as the demand for the liquid crystal display device increases recently, mass production of the liquid crystal display device is required, thereby simplifying and reducing the number of these elements.

 Hereinafter, a liquid crystal display according to still another exemplary embodiment of the present invention will be described in detail with reference to FIGS. 11 and 12. 11 is a cross-sectional view of the liquid crystal display according to still another exemplary embodiment cut in the horizontal direction. 12 is a cross-sectional view of a liquid crystal display according to still another exemplary embodiment in a vertical direction. For convenience of description, members having the same functions as the members shown in the drawings of the above embodiment are denoted by the same reference numerals, and thus description thereof is omitted. The liquid crystal display device 102 according to the present exemplary embodiment has the same structure as the liquid crystal display device 100 according to the exemplary embodiment of the present invention except for the following. That is, as shown in FIGS. 11 and 12, the liquid crystal display device 102 according to the present exemplary embodiment is disposed between the optical sheet 142 and the liquid crystal panel 110 disposed on the diffuser plate 141 to provide optical The spacer 415 further separates the sheet 142 and the liquid crystal panel 110.

11 and 12, in the liquid crystal display device 102 according to the present exemplary embodiment, a spacer 415 is interposed between the optical sheet 142 and the liquid crystal panel 110 to space them apart.

In the same manner as in the previous embodiments, the lower storage space of the hollow mold 202 for accommodating the liquid crystal panel and the diffusion plate is defined, and the second end 232 serving as a supporting function has a diffuser plate 141 and an optical sheet from the bottom to the top. 142 is disposed.

Unlike the previous embodiments, the spacer 415 is disposed along the edge of the optical sheet 142, and the liquid crystal panel 110 is disposed on the spacer 415. The spacer 415 may be formed in a rectangular strip shape having a predetermined thickness, in which case the height of the first end 231 and the second end 232 of the hollow mold 202 for accommodating the liquid crystal panel and the diffusion plate. The difference may be larger by the thickness of the spacer 415, but the thickness of the liquid crystal display device 102 is reduced since the thickness decreases as compared with the case in which the gap between the liquid crystal panel 110 and the optical sheet 142 is maintained by the middle mold. It does not impede it.

The spacer 415 may be made of a flexible polymer resin so that scratches do not occur in the liquid crystal panel 110 and the optical sheet 142. The rubber material has elasticity in consideration of a work tolerance when assembling the top chassis 180. It may be made of. In addition, the spacer 415 may be a material having both elasticity and ductility.

By using the spacer 415 so that the liquid crystal panel 110 and the optical sheet 142 are spaced apart from each other, scratches are generated due to friction between the liquid crystal panel 110 and the optical sheet 142 and thus the liquid crystal panel 110 or the like. As well as preventing damage to the optical sheet 142, it is possible to prevent foreign matters from occurring.

In the present embodiment, the shape and fixing method of the reflective sheet 150 and the storage position of the liquid crystal panel 110 and the diffusion plate 141 are not the same as in the previous embodiments.

According to the liquid crystal display device 102 according to the present embodiment, the spacer 415 is disposed between the liquid crystal panel 110 and the diffusion plate 141 to generate scratches of the liquid crystal panel 110 and the optical sheet 142. Accordingly, the generation of foreign substances is suppressed, and the thickness of the liquid crystal display device 102 is reduced and integrated as compared with the case in which the liquid crystal panel 110 and the diffusion plate 141 or the optical sheet 142 are spaced apart by using a middle mold. By using the hollow mold 202 for accommodating the liquid crystal panel and the diffusion plate, the assembly process can be simplified. In addition, it is possible to fix easily by adopting the flat sheet-like reflective sheet 150 and fixing the hollow mold 202 for storing the liquid crystal panel and the diffusion plate.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

As described above, according to the liquid crystal display, the liquid crystal panel, and the hollow mold for diffusing the plate according to the embodiments of the present invention, there are one or more of the following effects.

First, by using an integrated liquid crystal panel having two storage spaces and a hollow mold for receiving a diffusion plate, the number of parts can be reduced, thereby reducing the material cost.

Second, by adopting a flat sheet-shaped reflective sheet and fixing it to the inclined surface of the hollow mold for housing the liquid crystal panel and the diffusion plate, the shape of the reflective sheet can be simplified and the fixing method can be automated.

Third, a liquid crystal display device having a reduced thickness may be provided by eliminating or reducing the separation gap between the liquid crystal panel and the diffusion plate.
