The entire thickness of the LCD is increased, which limits the thinness of the display device. In addition, the LCD having the above-described structure is complicated in the assembly process due to a large number of components, takes a long time to assemble, and thus has a disadvantage in that the production amount is reduced and the manufacturing cost is increased.

In order to solve the above-mentioned problems, in recent years, as shown in FIG. 2 in Korean Patent Laid-Open No. 10-2014-0061061 (prior art), a cover bottom, a guide panel, a middle cabinet and a front cover are removed, Discloses a technique for implementing a display device using only the display device 24.

The thin LCD of the prior art document has a structure in which the liquid crystal panel 21 is directly fastened to the back cover 24 along the edge of the back cover 24 so that the edge portion of the liquid crystal panel 21 is exposed to the outside. In order to expose the edge of the liquid crystal panel 21 to the outside, the liquid crystal panel 21 must have a GIP (Gate In Panel) structure in which the gate driving circuit is disposed inside the panel. That is, only the liquid crystal panel of the GIP structure capable of exposing the edge of the panel can be applied to the thin LCD of the above-mentioned prior art, and the liquid crystal panel of the general structure (Non-GIP) There are disadvantages.
