In addition, the flexible substrate 119 of the liquid crystal display 100 passes through the hole 520 of the main housing 500 and is connected to the main board 107 disposed in the lower storage space of the main housing 500. The main board 107 and the power supply module 108 including the 500 are mounted in the rear housing 400. In addition, the front housing 300 is coupled to the upper portion of the liquid crystal display 100 to form one mobile device.

Hereinafter, a mobile device including a liquid crystal display according to another embodiment of the present invention will be described with reference to the drawings.

7 is a view showing a portion of the cross-section before assembling the mobile device according to another embodiment of the present invention.

Referring to FIG. 7, in the mobile device of the present invention, a predetermined protruding portion 500a is formed in the main housing 500, and the guide panel supports the liquid crystal panel 113 of the liquid crystal display 113. At least one side end of the 116 is characterized in that the recessed portion (116a) is further formed to engage the above-mentioned convex portion.

The protrusion 500a may be formed on all inner surfaces or some inner surfaces of the main housing 500, and may be formed in a dot shape or a straight shape. Correspondingly, a depression 116a through which the protrusion 500a can be inserted is formed on the outer side of the guide panel 116 of the liquid crystal display 113, and the transfer or other external force of the assembled mobile device as the two parts are combined. When applied, it is possible to minimize the flow of the liquid crystal display 113.

The above-mentioned concave-convex structure may be formed by changing their shapes. That is, the structure in which the protrusion part 500a and the depression part 116a are formed in the guide panel 116a and the main housing 500, respectively is also applicable.

Many details are set forth in the foregoing description but should be construed as illustrative of preferred embodiments rather than to limit the scope of the invention. Therefore, the invention should not be defined by the described embodiments, but should be defined by the claims and their equivalents.
