Therefore, the display module seating member 370 uses a sheet made of stainless steel (STS) or aluminum.

9 is a combined perspective view of a window and a display module according to an embodiment of the present invention.

Meanwhile, FIG. 11 is a perspective view of the adhesive member 360 according to the embodiment of the present invention, and FIG. 12 is a cross-sectional view of the adhesive member 360 according to the embodiment of the present invention. The adhesive member 360 according to an embodiment of the present invention is formed to extend from the first portion 360a and the first portion 360a formed between the display module 300 and the window 400 and bend. A second portion 360b, a third portion 360c extending from the second portion 360b, and disposed on a side surface of the display module seating member 370, and extending from the third portion 360c, It is divided into a fourth portion 360d formed up to a point on the back surface of the display module seating member 370.

13 is a combined cross-sectional view of a window and a display module related to another embodiment of the present invention, according to which, the adhesive member 360 is a first portion 360a formed between the display module 300 and the window 400 ), A second portion 360b extending from the first portion 360a and formed to be curved, and a second portion extending from the second portion 360b, and a point on the side of the display module seating member 370 It may include a third portion 360c disposed up to and a fourth portion 360d attached to the outside of the third portion 360c and formed up to a point on the rear surface of the display module seating member 370.

On the other hand, the adhesive member 360, as shown in Figure 12 a, the support layer 364 on both sides of the adhesive layer 362 is formed on a double-sided tape, or as shown in Figure 12 b, the support layer 364 ) May be a single-sided tape on which an adhesive layer 362 is formed. Furthermore, the adhesive layer 362 may not be formed on both sides of the support layer 364.

More specifically, the first portion 360a may be a double-sided tape as shown in FIG. 12A, and the third portion 360c may be a single-sided tape as shown in FIG. 12B. At this time, the double-sided tape has a support layer 364 in the middle, and an adhesive layer 362 is formed on both sides of the support layer 364. The support layer 364 may be a PET film, and the adhesive layer 362 ) May be an OCA film.

As described above, in one embodiment of the present invention, a supporting layer 362 is provided in addition to the adhesive layer 362, which cannot fix the display module 300 when using a liquid adhesive. Therefore, in one embodiment of the present invention, the display module 300 can be fixed using a transparent member such as PET.

On the other hand, the adhesive member 360 disposed between the window 400 and the display module 300 should be a double-sided adhesive member, whereas an area other than this, that is, a double-sided adhesive member on the side and back of the display module 300 no need. In particular, since an additional configuration is not attached to the side surface of the display module 300, and more specifically, the side surface of the display module seating member 370, the support layer 364 may be simply provided. However, in one embodiment of the present invention, the adhesive layer 362 is formed only on one surface of the support layer 364 on the double-sided tape having the adhesive layer 362 formed on both sides of the support layer 364 in the second portion 360b. It may be formed of a single-sided tape, or only a simple support layer 364 in which the adhesive layer 362 is not formed on both sides of the support layer 364. The single-sided tape or the simple support layer extends to the third portion 360c, and the third portion 360c is not attached to the side surface of the display module seating member 370, but is in simple contact. To this end, the adhesive layer 362 formed on the portion facing the display module 300 in the second portion 360b must be removed.

In addition, an adhesive layer 362 is formed on at least one surface of the support layer 364 of the fourth portion 360d, and an elastic adhesive means 380 is attached to the back surface of the fourth portion 360d. The means 380 is to be able to withstand the impact when the display module 300 is seated on the terminal body. At this time, the adhesive means 380 may use a double-sided tape, when the adhesive means 380 is a double-sided tape, the fourth portion 360d is formed with an adhesive layer 362 only on one surface of the support layer 364 It is enough.

As described above, the adhesive member 360 is fixed to the LCD panel 310 and the backlight module 320 embedded in the display module 300 so as to be integrally formed so as to be integrally formed with a side surface on the rear surface through the side surface of the display module. Extend to.

Meanwhile, according to an embodiment of the present invention, as illustrated in FIGS. 8 and 10A to 10D, the upper polarizing plate 312a may be disposed on the same line as the color filter layer 314. This is because when using a liquid adhesive (adhesive) as the adhesive member 360, it takes about 3 days to harden, so if working before the adhesive member 360 is completely hardened, air bubbles may flow in. In order to prevent this, the upper polarizing plate 312a is projected more forward.

Hereinafter, a process of integrating the display module 300 at the same time as attaching the window 400 and the display module 300 will be described with reference to FIGS. 10A to 10D.

Munder, referring to FIG. 10A, attaches them using an adhesive member 360 made of double-sided tape between the window 400 and the display module 300, which is formed up to point a. Thereafter, as shown in FIG. 10B, the paper 361 is removed. At this time, at one point in the section between a and b, the adhesive layers 362 formed on both sides of the support layer 364 are removed from one side or both sides. When only one side is removed, the adhesive layer 362 formed on the side facing the display module seating member 370 is removed. In addition, as in points a and b, bending is performed using a jig in a bending section.

Next, as shown in FIG. 10C, the adhesive member 360 is bent at point c to adhere to the back surface of the display module seating member 360, and finally, as shown in FIG. 10D, the display module 300 Is seated on the case 410.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 13.

13 is a cross-sectional view of a defect of the window 400 and the display module 300 according to an embodiment of the present invention, except that the adhesive member 360 is not formed integrally and is formed separately and coupled, as described above. same.

That is, the window 400 and the display module 300 are attached and coupled to the first adhesive member 360, and the first adhesive member 360 extends to a side point of the side surface of the display module seating member 370. 2 The adhesive member 366 is formed on the outside of the first adhesive member 360 and is simultaneously attached to the first adhesive member 360 and attached to the rear surface of the display module seating member 370. At this time, the second adhesive member 366 attached to the rear surface of the display module seating member 370 corresponds to the fourth portion 360d described above. That is, both double-sided or single-sided tapes are possible.

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