According to the configuration as described above, the display module 240 may be fixed to the terminal body by arranging the display module 240 on the seating portion 210 and thermally fusion under specific temperature and pressure conditions. That is, since a process such as bonding or taping, which is a bonding process of the existing display module 240, is unnecessary, the bonding process may be simplified.

The elastic bonding layer 250 may be any one of a film layer, a spray layer, or a coating layer covering the seating portion 210. The elastic bonding layer 250 may be formed of, for example, polycarbonate (PC) or polyethylene terephthalate (PET).

The front and / or rear cases 101 and 102 may be formed of a metal material, for example, stainless steel or aluminum, in order to improve durability and enhance the appearance. When a portion accommodating the display module 240 is formed of a metallic material, such as the seating portion 210 which is a part of the front case 101, the display module 240 may be damaged during external impact due to the characteristics of the metallic material.

However, according to the above structure, the elastic bonding layer 250 absorbs the shock transmitted between the display module 240 and the seating portion 210, and has all the functions of being coupled with the display module 240. There is no need for a separate adhesive member such as an injection molding and a tape covering a portion in contact with the display module 240.

Accordingly, the width of the bezel may be reduced through a simpler coupling structure, and the area of the display 242 may be maximized relative to the main area of the terminal body.

The mounting unit 210 may include a protrusion 220 formed to protrude along the circumference of the display module 240. The surface treatment layer 260 may be disposed on the upper surface of the protrusion 220 to improve the appearance. The surface treatment layer 260 may be, for example, an ultraviolet cured layer formed of a material that is cured by ultraviolet (UV) irradiation.

The ultraviolet curable layer is disposed to cover the protrusion 220 to protect the terminal body from an external environment such as scratching, discoloration, oxidation, and the like. In addition, it is possible to form a more advanced appearance through the gloss treatment.

One surface of the display module 240, that is, the upper surface of the window 241 and the surface treatment layer 260 may form the same plane. The surface treatment layer 260 may be formed to extend from the top surface of the window 241 without a step so that a simple appearance may be realized.

6 is an exploded perspective view of another example of a mobile terminal 100 according to the present invention, and FIG. 7 is a cross-sectional view taken along the line VIII-V shown in FIG.

6 and 7, the mobile terminal 100 ′ according to the present exemplary embodiment has the same configuration as the mobile terminal 100 described above except for the coupling structure of the display module 340. Therefore, hereinafter, the description will be given based on the coupling structure of the display module 340 detachable from the terminal body.

The mobile terminal 100 ′ is provided with a locking unit 370 configured to couple or uncouple the display module 340 to the seating unit 310. The locking part 370 includes a locking groove 371 and a locking hook 372.

The catching groove 371 is formed to be recessed on one surface of the seating part 310, and forms a space to accommodate the catching hook 372. As shown, the locking groove 371 may be formed to be recessed in a surface facing the side of the display 342.

The elastic coupling layer 350 is coupled to the rear surface of the window 341, specifically, the surface facing the bottom surface of the seating portion 310. The locking hook 372 is fixed to the elastic coupling layer 350 and is detachably coupled to the locking groove 371.

That is, the display module 340, the elastic coupling layer 350, and the hook hook 372 may be formed as one module. According to the above structure, the display module 340 may be coupled to or released from the seating unit 310 through the locking unit 370. Accordingly, the mobile terminal 100 ′ capable of reworking the display module 340 may be provided.

A damper 380 may be further disposed between the display module 340 and the hook hook 372. The damper 380 is formed to absorb the shock that the hook hook 372 transmits to the display module 340. The damper 380 may be formed of a silicon or rubber material capable of elastic deformation. Since the damper 380 is disposed together with the elastic coupling layer 350, an impact amount transmitted to the display module 340 may be further reduced.

The mobile terminal described above is not limited to the configuration and method of the embodiments described above, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made.
