According to various embodiments, a polarizing member 525 may be included between the transparent cover 510 and the display panel 520 to transmit light corresponding to a designated direction. The polarization member 525 is attached to the transparent cover 510 through a first adhesive layer (eg, OCA (optical clear adhesive)) (not shown) on the upper surface, and a second adhesive layer (not shown) on the lower surface. It can be attached to the display panel 520 through. The type of adhesive layer used for attaching the polarizing member 525 is not defined.

According to various embodiments, the polarization member 525 may include a touch sensor for touch sensing. That is, the display device 300 may include a polarization member-integrated touch sensor. According to another embodiment, the touch sensor is laminated under or on the display panel 520 as a separate layer, formed on the display panel 520 (on-cell type), or formed inside the display panel 520. It can be (in-cell type).

Under the display panel 520, a black layer 531, a support layer 532, a tape layer 533, a digitizer 534, and a heat dissipation member 535 (eg, the heat dissipation member 430 of FIG. 4) are included. It may include at least one layer 530 to do. The black layer 531 and the supporting layer 532 are intended to absorb shock to the display panel 520 .

At least one area of the release member 560 is attached to the lower surface of the first area where the adhesive member 540 is disposed, and at least one other area is attached to the lower surface of the second area where the compensating member 550 is disposed. can In other words, the release member 560 may cover all or part of the adhesive member 540 and the compensating member 550 from the lower surface.

According to one embodiment, the compensation member 550 and the release member 560 may be integral. That is, since the compensation member 550 and the release member 560 are made of a single polymer, when separated from the display device 300, the compensation member 550 and the release member 560 may be separated at once.

According to another embodiment, the compensation member 550 and the release member 560 may be separately generated and attached. In this case, the adhesive force of the adhesive surface between the compensation member 550 and the release member 560 is stronger than the adhesive force of the adhesive surface between the adhesive member 540 and the release member 560, and the compensation member 550 and the release member 560. The adhesive force of the adhesive surface between the layers 560 may be stronger than the adhesive force of the adhesive surface of the compensating member 550 and the at least one layer 530 . Accordingly, when force is applied to the release member 560 in the downward direction, the release member 560 and the compensation member 550 are separated due to a difference in adhesive force, and the adhesive member 540 is bonded to the heat dissipation member 535 can keep According to another embodiment, the adhesive strength between the compensating member 550 and the release member 560 is weak, so that when manufacturing an electronic device (eg, the electronic device 101 of FIG. 1 ), the display device 300 first After separating the release member 560, the compensating member 550 may be separated.

It may be greater than the width of at least a portion of the panel 520 . For example, as shown in FIG. 5 , the transparent cover 510, the polarization member 525, the display panel 520, and the black layer 531 are sequentially positioned in the upper direction in the display device 300. Its width may decrease. As described above, the area where the width is reduced for each layer may be an edge area of the display device 300 . Accordingly, in the edge area, each layer of the display device 300 may be combined in a form in which the transparent cover 510 surrounds the components disposed below in a downward direction.

6 illustrates a state when a display device is mounted on an electronic device according to various embodiments.

According to various embodiments, an adhesive member 640 (eg, the adhesive member 440 of FIG. 4 ) and a compensation member (eg, the compensation member 450 of FIG. 4 ) disposed on the same plane, and the adhesive member 640 And the release member (eg, the release member 560 of FIG. 5) disposed on the lower surface of the compensation member may be removed during a process of coupling the display device to the electronic device (eg, the electronic device 101 of FIG. 1). have.

In addition, at least a part of the main FPCB 660 of the electronic device may be disposed in the third area where the compensating member and the adhesive member 640 are not disposed.

In the manufacturing process of the electronic device, the effect of compensating for the level difference next to the adhesive member with the compensating member is as follows.

As a result of an accelerated life test (ALT) under the conditions of about -10 degrees to about +60 degrees and about 90% humidity, the lift after 72 hours before step compensation was applied using a compensation member was 1/10. However, as a result of arranging the compensating member, no lifting occurred for 120 hours.

7A and 7B illustrate steps between components of a display device at each position of an electronic device according to various embodiments.

According to various embodiments, the electronic device 700 (or the display device 300) has a width of at least a portion of a layer (eg, the transparent cover 710) disposed above (eg, the front surface of the electronic device) has a lower width. It may be greater than the width of at least a portion of a layer (eg, the display panel 720) disposed on (eg, the rear surface of the electronic device). Accordingly, a configuration in which a transparent cover 710 (eg, the transparent cover 510 of FIG. 5) is disposed below (eg, a polarizing member 725 (eg, the polarizing member 525 of FIG. 5)), a display panel ( 720) (eg, the display panel 520 of FIG. 5) may be coupled to each layer of the display device 300 in a form of wrapping downward. According to various embodiments, the polarization member 725 may include a touch sensor for touch sensing.

For example, as shown in FIG. 7B , the width of the transparent cover 710 may be greater than that of the polarization member 725, and the width of the polarization member 725 may be greater than that of the display panel 720. have. Accordingly, when the transparent cover 710, the polarization member 725, and the display panel 720 are sequentially stacked, the edge area of the transparent cover 710 may partially protrude outward than the edge area of the polarization member 725. , The edge area of the polarization member 725 may partially protrude outside the edge area of the display panel 720 . In FIG. 7B , position 1 may be a corner area of the electronic device 700 (or display device 300), and position 2 may be an edge area on the top/bottom and left/right sides. A hall into which the stylus of the electronic device 700 is inserted may be disposed at any one of position 1 .

According to various embodiments, a difference in width between the transparent cover 710 , the polarization member 725 , and the display panel 720 in each region of the display device 300 may be different from each other.

For example, the width of the first portion of the polarization member 725 is greater than the width of the first portion of the display panel 720 by a first degree, and the width of the second portion of the polarization member 725 is greater than the width of the first portion of the display panel 720. ) by a second degree greater than the width of the second portion, and the first degree may be greater than the second degree. According to various embodiments, the first part is the corner area (eg, position 1) of the polarization member 725 and the display panel 720, and the second part is the edge area of the polarization member 725 and the display panel 720. (e.g. position 2).

Referring to FIGS. 7A and 7B , the difference in width between the polarization member 725a and the display panel 720a in the corner region (or first portion) of the polarization member 725a and the display panel 720a is, for example, It may be about 0.4 mm.

In contrast, the polarization member 725b and the display panel 720b are formed at the upper/lower end portions and the left/right side portions (position 2) corresponding to the edge area (or second portion) of the polarization member 725b and the display panel 720b. The width difference between the spaces may be about 0.1 mm, which is smaller than that of the corner area.

This is because the polarization member 725 covers the force applied to the display panel 720 in the lateral direction by forming a larger width difference between the polarization member 725 and the display panel 720 in the curved corner area. An impact received by the display panel 720 may be reduced.

According to one embodiment, the thickness of the black layer 831 may be about 50 μm to about 60 μm. For example, the thickness of the pressure sensitive adhesive (PSA) 831a on the upper surface of the polyethylene terephthalate (PET) 831b of the black layer 831 is set to about 38 μm, and the thickness of the PSA 831c on the lower surface is set to about 38 μm. The thickness can be set to about 15 μm. This is thicker than the thickness of the PSA (eg, about 23 μm / 10 μm) of the conventional display device 300, and the adhesive strength at room temperature increases from about 1096 gf / in of the conventional display device 300 to about 2000 gf / in has the effect of

According to one embodiment, the thickness of the support layer 832 may be set to about 150 μm or more. When the thickness of the support layer 832 increases from about 100 μm to about 150 μm, the height capable of impact resistance upon ball drop increases from about 16 cm to about 23 cm. In this case, the impact resistance performance of the display device 300 is improved by about 43%.

According to an embodiment, the display device 300 uses an adhesive in the heat dissipation member 835 (eg, the heat dissipation member 535 of FIG. 5 ) at room temperature rather than the heat curing type adhesive of the conventional display device 300 . Curing type adhesives 835a and 835c may be used. As illustrated, adhesives on the upper and lower surfaces of the graphite 835b of the heat dissipation member 835 may be room temperature curing type adhesives 835a and 835c. In this case, a repulsive force between the heat dissipating member 835 and the upper panel layer (eg, black layer 831, digitizer 834 (eg, digitizer 534 of FIG. 5), etc.) has an effect of being reduced.
