The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device which is easily transported during production.

Liquid crystal display is one of the most widely used flat panel displays. It consists of two substrates on which electrodes are formed and a liquid crystal layer interposed between them. The display device is applied to rearrange the liquid crystal molecules of the liquid crystal layer to control the amount of light transmitted.

Such a liquid crystal display device includes a liquid crystal panel including a pair of substrates having a liquid crystal layer interposed therebetween, and a backlight assembly providing light passing through the liquid crystal panel. Here, the backlight assembly includes a plurality of lamps, various optical sheets, a diffusion plate, and upper and lower storage containers for storing them.

Looking at the production process of the liquid crystal display of the prior art, the gripper of the jig (jig) is inserted in the gap between the upper housing and the lower housing, and then lifted and transported the liquid crystal display. Recently, as efforts to widen the effective display area of the liquid crystal display device continue, the bezel of the upper storage container exposing the liquid crystal panel is being narrowed. In the case of the liquid crystal display having such a structure, there is a problem in that it is difficult to transport the liquid crystal display because there is not enough space for the gripper of the jig to be inserted between the upper and lower storage containers.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a liquid crystal display device which is easily transported using a jig.

The lamp 143 may be a cold cathode fluorescent lamp (CCFL), an external electrofluorescent lamp (EEFL), or the like. The lamp 143 generates light by a lamp driving voltage applied to the lamp 143 from the outside. In addition, the lamps 143 may be spaced apart at a uniform distance and connected in phase in parallel, and may be configured in a direct type. The lamp 143 is preferably arranged in the transverse direction with respect to the liquid crystal panel 136 so that the distribution of the discharge gas inside the lamp 143 is constant to obtain uniform luminance. A lamp socket (not shown) may be formed at an end of the lamp 143 to provide a lamp driving voltage to the lamp 143 to support and fix the lamp 143.

The diffusion plate 142 may be installed on the upper portion of the lamp 143, and serves to improve luminance uniformity of light generated from the lamp 143.

The reflection plate 144 is installed under the lamp 143 to reflect the light emitted to the bottom of the lamp 143 to the top. The reflecting plate 144 may be integrally formed on the bottom surface of the lower storage container 160. That is, the lower receiving container 160 may be made of a material having high reflectivity such as aluminum (Al) or an aluminum alloy so that the lower receiving container 160 may perform a function of the reflecting plate 144.

The lamp 143 may be fixed by the lamp fixing unit 145 disposed on the reflector plate 144.

The optical sheets 141 are installed on the diffusion plate 142 and serve to diffuse and collect light transmitted from the lamp 143. The optical sheets 141 include, for example, a diffusion sheet, a first prism sheet, a second prism sheet, and the like.

In this case, the diffusion sheet is positioned above the lamp 143 and serves to improve brightness and uniformity of light incident from the lamp 143.

The first prism sheet is positioned above the diffusion sheet, and one surface of the first prism sheet has a triangular prism pattern (not shown) for condensing and emitting light diffused from the diffusion sheet and having a constant arrangement. For example, a brightness enhancement film may be used as the first prism sheet.

The second prism sheet is a reflective polarizing prism sheet having a multi-layered structure positioned on the first prism sheet and condensing and polarizing light. For example, a dual brightness enhancement film may be used as the second prism sheet. However, if only the first prism sheet can sufficiently secure the luminance and the viewing angle, the second prism sheet may be excluded.

The optical sheets 141 may be variously changed according to the specification of the backlight assembly 140.

The reflective plate 144, the lamp 143, the diffusion plate 142, and the optical sheets 141 are sequentially stored in the lower storage container 160, and the storage frame 150 is the lower storage container 160.

Consists of A fixing hook (not shown) is formed on the bottom of the plate and penetrates the reflecting plate 144 to engage with an opening (not shown) formed in the bottom surface of the lower storage container 160. 160 may be fixedly coupled.

The printed circuit board 135 of the liquid crystal panel assembly 130 is bent along the outer wall of the lower housing 160 to be seated on the sidewall or the rear surface of the lower housing 160. Here, the shape of the lower storage container 160 may be variously modified according to a method of accommodating the optical sheets 141, the diffusion plate 142, the lamp 143, and the reflective plate 144 in the lower storage container 160. Can be.

The upper accommodating container 110 is combined with the lower accommodating container 160 to cover an upper surface of the liquid crystal panel assembly 130 disposed on the accommodating frame 150. A window for exposing the liquid crystal panel assembly 130 to the outside is formed on an upper surface of the upper accommodating container 110.
