And a liquid crystal layer interposed between the filter substrate and the two substrates.

Such a liquid crystal display device has a plurality of unit liquid crystal display panels formed on a large size mother substrate, and is completed through a cutting process.

The liquid crystal display device is horizontally supported from the pallet and transferred to an assembly process such as top case assembly or to a packaging process.

In general, a pallet for a liquid crystal display device has a structure in which a support plate in contact with the liquid crystal display device is fixed by a plurality of support bars on a surface type main plate.

The support plate generally has a structure that is separated to support edges of both lower surfaces of the liquid crystal display.

However, in general, a pallet for a liquid crystal display device has a problem in that the size and weight of the liquid crystal display device increase and the center portion of the liquid crystal display device sags downward as the size of the liquid crystal display device increases.

The central deflection of the liquid crystal display device causes a problem that assembly failure occurs due to interference between components in the assembly process.

In addition, the general liquid crystal display palette has a problem in that the type of the pallet increases according to the size and weight of the liquid crystal display device, the manufacturing cost according to the palette production.

In addition, in general, a pallet for a liquid crystal display device uses a lower plate as an aluminum disc, which causes a weight increase as the liquid crystal display device becomes larger.

In addition, the general palette has a problem in that when the liquid crystal display device of a specific size is discontinued, the corresponding palette cannot be used.
