Abstract

A display device includes a display panel including a first area and a second area, which are arranged in a first direction, a first support layer disposed below the display panel, overlapping the first area, and including a plurality of openings, a plurality of support bars spaced apart from each other in the first direction, disposed below the first support layer, and extending in a second direction intersecting the first direction, and a bonding member disposed between the first support layer and the plurality of support bars and including a bonding metal.

Claims (32)

1 . A display device comprising:

a display panel comprising a first area and a second area, which are arranged in a first direction;

a first support layer disposed below the display panel, overlapping the first area, and including a plurality of openings;

a plurality of support bars spaced apart from each other in the first direction, disposed below the first support layer, and extending in a second direction intersecting the first direction; and

a bonding member disposed between the first support layer and the plurality of support bars, the bonding member comprising a bonding metal,

wherein each of the plurality of support bars and the bonding member does not overlap the plurality of openings of the first support layer in a plan view.

2 . The display device of claim 1 , wherein the bonding metal comprises at least two of nickel, copper, tin, silver, and zinc.

3 . The display device of claim 1 , wherein the bonding member comprises:

silver having an amount of about 33 wt % or more to about 58 wt % or less,

4 . The display device of claim 1 , wherein

the bonding member comprises an upper surface adjacent to the first support layer and a lower surface adjacent to the plurality of support bars,

the upper surface of the bonding member is in contact with a lower surface of the first support layer, and

the lower surface of the bonding member is in contact with an upper surface of each of the plurality of support bars.

5 . The display device of claim 1 , wherein the bonding member has a thickness of about 1 μm or more to about 20 μm or less.

6 . The display device of claim 1 , wherein

the first support layer comprises a first metal different from the bonding metal, and

each of the plurality of support bars comprises a second metal different from the bonding metal.

7 . The display device of claim 6 , wherein each of the first metal and the second metal comprises stainless steel.

8 . The display device of claim 6 , wherein the first support layer comprises:

a first sub-support layer comprising the bonding metal and the first metal; and

a second sub-support layer comprising the first metal.

9 . The display device of claim 6 , wherein each of the plurality of support bars comprises:

a third sub-support layer comprising the bonding metal and the second metal; and

a fourth sub-support layer comprising the second metal.

10 . The display device of claim 1 , further comprising:

a cover layer disposed between the display panel and the first support layer.

11 . The display device of claim 1 , further comprising:

a second support layer disposed below the display panel, overlapping the second area, and spaced apart from the first support layer in the first direction.
