A plurality of second coupling members192b1and192b2may be formed. The plurality of second coupling members192b1and192b2may be spaced apart in the horizontal direction.

The first coupling members192a1and192a2may have a substantially same vertical length as the second coupling members192b1and192b2. Alternatively, the first coupling members192a1and192a2may have a different vertical length from the second coupling members192b1and192b2.

Since the first coupling members192a1and192a2and the second coupling members192b1and192b2are formed to be long in the vertical direction, the display panel110can more stably maintain a constant distance from the main frame130. In addition, since the first coupling member192a1and192a2and the second coupling member192b1and192b2are fastened to be long in the vertical direction, in addition to preventing the display panel110from moving left and right in advance, it is possible to more effectively prevent a phenomenon in which the central area of the display panel110is inclined toward the front.

A plurality of second coupling members193b1and193b2may be formed. The plurality of second coupling members193b1and193b2may be spaced apart in the horizontal direction. A distance between the second coupling members193b1and193b2may gradually increase as it proceeds from the top to the bottom.

Since the first coupling members193a1and193a2and the second coupling members193b1and193b2are formed in the diagonal direction, the display panel110can be fastened to the main frame130at a correct position. In addition, since the first coupling members193a1and193a2and the second coupling members193b1and193b2are fastened in the diagonal direction, it is possible to more stably maintain a constant distance.

Referring toFIG.12(a), a first coupling member194amay include a fastening area91cfastened to the support plate170and an extending area93cextended from one side of the fastening area91c.

Referring toFIGS.13to15, a display device300may include the display panel110, a main frame330and an inner plate350.

The display panel110is provided on a front surface of the display device300and can display images.

The main frame330may be disposed behind the display panel110. The main frame330may be coupled to the display panel110. In order for the main frame330to be coupled to the display panel110, the main frame330and/or other structures adjacent thereto may include a protruding part, a sliding part, a coupling part, and the like.

An edge of the main frame330may be bent at least once toward the outside.

The main frame330may include a bottom frame331. The bottom frame331may be disposed under the main frame330. The bottom frame331may be separated from or coupled to the main frame330. The main frame330and the bottom frame331may cover the side surfaces of the display panel110.

The inner plate350may face the support plate170mounted on the back surface of the display panel110. The inner plate350may be connected to or coupled to the support plate170through coupling members351and353.

The coupling members351and353may couple the inner plate350to the support plate170. The coupling members351and353may be disposed on the front surface of the inner plate350.

The coupling members351and353may include magnetic members351and351ahaving magnetism and adhesive members353and353acoated with adhesive. For example, the magnetic members351and351amay be magnets, and the adhesive members353and353amay be double-sided tapes.

The magnetic members351and351amay be disposed in an upper area of the inner plate350. The adhesive members353and351amay be disposed in a lower area of the inner plate350.

When the display panel110is separated from the inner plate350, a manager can detach it while pulling an upper part of the display panel110. By arranging the magnetic members351and351ahaving lower adhesive strength than the adhesive members353and351ain the upper area of the inner plate350, the manager can more easily separate the display panel110from the inner plate350.

A plurality of magnetic members351and351amay be arranged in M rows and N columns (M and N are natural numbers) in the upper area of the inner plate350. The number of the magnetic members351disposed in the first row may be different from the number of the magnetic members351adisposed in the remaining rows except the first row. For example, the number of the magnetic members351disposed in the first row may be greater than the number of the magnetic members351adisposed in the remaining rows except the first row.

That is, the number of the magnetic members351disposed close to an upper border or edge of the display panel110is greater than the number of the magnetic members351adisposed in the central area of the display panel110, so that it is possible to prevent in advance the border of the display panel110and a border of the inner plate350from being randomly separated.

A plurality of adhesive members353may be disposed to be horizontally long in the lower area of the inner plate350. The plurality of the adhesive members353may be spaced apart in the horizontal direction. The plurality of the adhesive members353are disposed in the lower area of the inner plate350, so that it is possible to prevent in advance the border of the display panel110and the border of the inner plate350from being randomly separated.

In addition, the display device300may prevent the display panel110from slipping on the inner plate350by a shearing force (force applied in a direction parallel to the front surface or back surface of the display panel).

Referring toFIG.16, the plurality of magnetic members351may be arranged in M rows and N columns (M and N are natural numbers) in the upper area of the inner plate350. The number of the magnetic members351disposed in the first row may be different from the number of the magnetic members351bdisposed in the remaining rows except the first row. For example, the number of the magnetic members351disposed in the first row may be greater than the number of the magnetic members351bdisposed in the remaining rows except the first row.

That is, the number of the magnetic members351disposed close to an upper border or edge of the display panel110is greater than the number of the magnetic members351adisposed in the central area of the display panel110, so that it is possible to prevent in advance the border of the display panel110and the border of the inner plate350from being randomly separated.

A plurality of adhesive members353b1and353b2may be disposed to be vertically long in the lower area of the inner plate350. The plurality of adhesive members353b1and353b2may be spaced apart in the horizontal direction. The display device300arranges vertically the plurality of adhesive members353b1and353b2in the lower area of the inner plate350, so that it is possible to easily separate the display panel110from the inner plate350. That is, the adhesive members353b1and353b2is disposed to be long in the same vertical direction as the direction in which the display panel110and the inner plate350are separated, so that it is possible to have a lower adhesive force than the adhesive members353b1and353b2disposed in the horizontal direction. Accordingly, the administrator can more easily separate the display panel110from the inner plate350.

The plurality of adhesive members353b1and353b2may adjust the adhesive force by varying the width or materials from neighboring adhesive members353b1and353b2.

In addition, the display device300may prevent the display panel110from slipping on the inner plate350by the shearing force.

Referring toFIG.17, a plurality of magnetic members351cmay be arranged in M rows and N columns (M and N are natural numbers) in the upper area of the inner plate350.

The magnetic member351cmay form a relatively large area of the magnetic member351cto increase adhesion. At this time, a separation distance b between the magnetic members351cmay be shortened. For example, when it is assumed that the separation distance between the magnetic members351cshown inFIG.17is a second separation distance b, and the separation distance between the magnetic members351shown inFIG.16is a first separation distance a, the second separation distance b may be shorter than the first separation distance a.

An adhesive member353cmay be disposed to be long in the horizontal direction in the lower area of the inner plate350.

Referring toFIGS.18to20, the coupling member may connect or fasten the display panel110and the inner plate350with only magnetic members351d,351e, and351f.

The plurality of the magnetic members351dand351emay be arranged in M rows and N columns (M and N are natural numbers) on the inner plate350.

As a size or area of one magnetic member351d,351e,351fincreases, a separation distance between the magnetic members351d,351e,351fmay become shorter.

Referring toFIG.21, the magnetic members351may relatively thickly form thicknesses th1and th2of the magnetic members351to increase adhesion. For example, the thickness of the magnetic member351shown inFIG.21(a)may be referred to as a first thickness th1, and the thickness of the magnetic member351shown inFIG.21(b)may be referred to as a second thickness th2.

The first thickness th1may be substantially the same as the thickness of the magnetic member shown inFIGS.13to20. The second thickness th2may be formed to be thicker than the first thickness th1. Thus, since the magnetic member351may contain more magnetic material as the thickness increases, adhesion may be improved.

As described above so far, the coupling members351and353may adjust magnetic force or adhesive force by using the spacing between the magnetic members351, the thickness of the magnetic member351, and the area of the magnetic member351.

Looking atFIGS.22and23, the adhesive member353may include at least one layer.

The adhesive member353may include a first layer3ato a seventh layer3g.

The second layer3bmay be stacked on a top surface of the first layer3a. The second layer3bmay be an adhesive layer.

A third layer3cmay be stacked on a top surface of the second layer3b. The third layer3cmay be a PET film.

A fourth layer3dmay be stacked on a top surface of the third layer3c. The fourth layer3dmay be PU foam.

A fifth layer3emay be stacked on a top surface of the fourth layer3d. The fifth layer3emay be a PET film or TPU.

A sixth layer3fmay be stacked on a top surface of the fifth layer3e. The sixth layer3fmay be an adhesive layer.

The seventh layer3gmay be stacked on a top surface of the sixth layer3f. The seventh layer3gmay be an adhesive layer. The seventh layer3gmay be a protective layer. The seventh layer3gmay protect the sixth layer3f.

The adhesive members353b1and353b2may form a PET film having good adhesion between the second layer3band the fourth layer3dand between the fourth layer3dand the sixth layer3f. Thus, a PET film having good adhesion may be disposed between the adhesive layer and the PU foam, so that residues of the PU foam separated from both adherends (the display panel110and the inner plate350) can be easily removed.
