2 to 4 are longitudinal cross-sectional views along X-X 'direction of several examples of mobile terminals related to the present invention.

2 (b) is a view showing one of the embodiments in which the upper-layer polarizer 312 is exposed to the outside without the cover window 311. FIG. There may be a case 105 in which a full-length part is provided inside the case to protect and fix parts related to the liquid crystal display device 310. [ The case 105 may include a front case 101 exposed on the side and front of the mobile terminal 100 and a middle frame 104 supporting and supporting the front case 101.

The front case 101 may be coupled to the upper polarizer 312 of the liquid crystal display device 310. At this time, the upper polarizing plate 312 may have stiffness and hardness equal to or higher than that of the conventional cover window 311 (see Fig. 2 (a)). In order to perform the function of the basic liquid crystal display device, a liquid crystal display panel 313 exists under the upper polarizing plate 312. A backlight unit 314 for supplying light to the liquid crystal display panel 313 may be present.

In this case, the periphery of the upper polarizer 312 extends outwardly from the liquid crystal display panel 313, thereby providing a sufficient space for attachment to the front case 101. At this time, a tape 317 for coupling between the outer circumference of the upper polarizing plate 312 and the front case 101 is required.

3 is a view showing one of the embodiments in which the case is combined with the backlight unit portion of the liquid crystal display device. The liquid crystal display panel 313 and the backlight unit 314 may be arranged in the order of the back surface of the upper polarizer plate 312 in the same manner as in the above embodiment. The liquid crystal display panel 313 and the backlight unit 314 are not separated from each other because the upper polarizer plate 312 and the front case 101 are not directly connected to each other, It still needs to be fixed with the base 105. When the backlight unit 314 is directly fixed to the middle frame 104 of the case, there is a high possibility that the backlight unit 314 may be damaged by an external force. Therefore, a liquid crystal display-frame 315 may be additionally required to protect the backlight unit 314. Such a frame may be made of stainless steel for that purpose. The backlight unit 314 and the liquid crystal display-frame 315 supporting the backlight unit 314 are collectively referred to as a backlight unit 320. [ The liquid crystal display device 310 is peeled from the inside of the case 105 of the mobile terminal by attaching the liquid crystal display protective frame 315 and the middle frame 104 of the backlight unit unit 320 through the tape 317 .

In order to protect the upper polarizing plate 312 exposed on the front surface, an extension part protruding further in the front direction than the upper polarizing plate 312 is provided on the circumference of the case 105 to prevent the upper polarizing plate 312 Can be protected.

In this case, peeling of each layer can be prevented. However, unlike the previous example, since the upper polarizer 312 is not attached to the front case 101, the liquid crystal display panel 313 and the backlight unit 314 Pollution can be a problem. And a side surface protection material 318 for protection against this portion can be applied and protected. Or by applying a resin.

The outer circumferential portion of the back surface of the liquid crystal display panel 313 and the outer circumferential portion of the front surface of the backlight unit 314 can be prevented from being exposed to the outside of the liquid crystal display panel 313 and the backlight unit 314, As shown in Fig.

Alternatively, as shown in FIG. 4, the front outer peripheral portion of the backlight unit 314 may protrude in the front direction to have a side wall portion that covers the side surface of the liquid crystal display panel 313. In this case, unlike the previous embodiment, since it can be manufactured only through the patterning process without additional material, the cost reduction effect can be obtained.

5 is a vertical cross-sectional view of the mobile terminal according to the present invention in the YY 'direction, illustrating one embodiment for protecting a driving IC (I / C) for driving a liquid crystal display device .

The liquid crystal display panel 313 may have a basic configuration of a transistor panel (TFT glass panel) 501 and a color filter layer (C / F glass panel) 502 located in the front direction thereof. Furthermore, a liquid crystal layer 503 may exist between the transistor panel 501 and the color filter layer 502. The driver IC (I / C) 504 for driving the liquid crystal display device may form an extension portion so that the transistor panel 501 protrudes more than the color filter layer 502 for positioning on the transistor panel 501 , The drive IC (I / C) 504 can be placed on the protruding extension. In this case, there is a possibility that the driving IC (I / C) 504 abuts against the upper polarizing plate 312 to be damaged, and protection from this is required. Therefore, the thickness of the color filter layer 502 is sufficient to allow a sufficient space to be provided between the upper-layer polarizer 312 and the transistor panel 501. Here, the thickness of the color filter layer 502 may be an ideal thickness of 0.5t.

In addition, in order to further protect the driving IC (I / C) 504, a tape 317 is attached to an area facing the driving IC (I / C) 504 in the back surface of the upper polarizer plate 312 .

FIG. 6 is a graph showing the relationship between the direction of the YY 'direction (FIG. 6A) and the direction of the MM' direction (FIG. 6B) for an embodiment in which the periphery of the driving IC is filled with an additional material, Fig.

 Even if the driving IC (I / C) 504 is protected as in the above-described embodiment, further protection may be required. Therefore, additional filling of the transistor panel 501 in an area portion where the driving IC (I / C) 504 is not present among the extensions protruding from the color filter layer 502 is possible. This filling can be prevented by preventing the portion of the upper polarizing plate 312 closer to the driving IC (I / C) 504 from being stuck by the periphery of the driving IC (I / C) 504. It is possible to apply the synthetic resin to the filling part 505 for filling the space or to prevent stiction by inserting an additional pad (not shown).

FIG. 7 is a longitudinal sectional view taken along the line M-M 'for an embodiment in which an additional frame is added to the outer surface to prevent stiction of the upper polarizer.

An additional support frame 316 may be provided around the rear outer surface of the upper polarizer 312. The support frame 316 may be attached to the liquid crystal display protective frame 315 of the backlight unit 320, May be combined with the liquid crystal display protection frame 315 in the embodiment (see FIG. In this case, there is an advantage that the sagging of the upper polarizing plate 312 can be prevented more stably.

The above embodiments basically combine the components to each other to prevent peeling of each component of the liquid crystal display device 310 and further attach the coupling configuration to the case 105 to prevent peeling. Therefore, in order to fix the upper polarizing plate 312, a tape or the like must be attached to the outer periphery of the back surface of the upper polarizing plate 312, and attachment of such a tape may lead to increase of the bezel. Therefore, there is a need to fix the upper polarizing plate 312, the liquid crystal display panel 313, and the backlight unit 320 without using such a tape.

A part of the polarizing plate 312, the liquid crystal display panel 313, the backlight unit 314, and the like may be formed as a layer layer that is transparent in place of the tape and has sufficient rigidity such as OCA, PET, It is possible to prevent peeling of each part of the liquid crystal display device 310 through the member 319 surrounding the outer periphery of the liquid crystal display device. In this case, the back surface of the backlight unit 312 and the middle frame 104 may be connected by a tape 317.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
