Display device
A display device includes: a display module comprising a first non-folding area, a second non-folding area, and a folding area between the first non-folding area and the second non-folding area; and a support module under the display module to support the display module, the support module including: a base layer comprising at least one of a glass fiber, a carbon fiber, or an aramid fiber; and a support layer having an opening overlapping the folding area, wherein the support layer is on at least one of upper or lower portions of the base layer.
1 . A display device comprising:
a display module comprising a first non-folding area, a second non-folding area, and a folding area between the first non-folding area and the second non-folding area; and
a support module under the display module to support the display module, the support module comprising:
a base layer comprising at least one of a glass fiber, a carbon fiber, or an aramid fiber;
a support layer having an opening therethrough, the opening overlapping the folding area, wherein the support layer is on at least one of upper or lower portions of the base layer; and
a first filling member, different from the base layer, filling the opening through the support layer such that the first filling member extends across internal edges of the opening.
2 . The display device of claim 1 , wherein the support layer comprises a resin.
3 . The display device of claim 2 , wherein the resin comprises at least one of an acrylic resin, an epoxy resin, or a urethane resin.
4 . The display device of claim 1 , wherein the support module further comprises a plurality of spacers in the opening and spaced apart from each other.
5 . The display device of claim 4 , wherein the spacers comprise a first spacer having a first thickness and a second spacer having a second thickness smaller than the first thickness.
6 . The display device of claim 5 , wherein the first spacer is alternately arranged with the second spacer.
7 . The display device of claim 5 , wherein the support layer comprises a first support layer on the base layer and a second support layer under the base layer.
8 . The display device of claim 7 , wherein the support module comprises the first filling member filled between at least two of the first support layer, the first spacer, and the second spacer.
9 . The display device of claim 8 , wherein the support module comprises a second filling member filled between at least two of the second support layer, the first spacer, and the second spacer.
10 . The display device of claim 9 , wherein the support module comprises a third filling member overlapping the second spacer and on the second spacer, and a sum of a thickness of the third filling member and a thickness of the second spacer is equal to a thickness of the first spacer.
11 . The display device of claim 10 , wherein the first filling member comprises a same material as a material of the second filling member, and the third filling member comprises a material different from the material of the first filling member.
12 . The display device of claim 10 , wherein the first filling member, the second filling member, and the third filling member comprise a same material as each other.
13 . The display device of claim 10 , wherein the third filling member comprises a thermoplastic polyurethane.
14 . The display device of claim 9 , wherein the support module further comprises an adhesive layer on one surface of the support layer.
15 . The display device of claim 14 , wherein the first filling member, the second filling member, and the adhesive layer comprise a same material as each other.
16 . The display device of claim 1 , wherein the support layer comprises a first sub-support portion overlapping the first non-folding area and a second sub-support portion overlapping the second non-folding area.
17 . The display device of claim 16 , wherein the first sub-support portion comprises a lower first sub-support portion under the base layer and an upper first sub-support portion on the base layer, and the second sub-support portion comprises a lower second sub-support portion under the base layer and an upper second sub-support portion on the base layer.
18 . The display device of claim 17 , wherein the support module comprises a plurality of spacers under the base layer and between the lower first sub-support portion and the lower second sub-support portion.
19 . The display device of claim 17 , wherein the support module comprises a plurality of spacers on the base layer and between the upper first sub-support portion and the upper second sub-support portion.
20 . The display device of claim 17 , wherein the support module further comprises a filling material located at at least one of between the lower first sub-support portion and the lower second sub-support portion or between the upper first sub-support portion and the upper second sub-support portion.
