Flexible display device
A display device includes a display panel including a folding area and a nonfolding area located around the folding area, a panel bottom member under the display panel and overlapping with the folding area and the nonfolding area, and a first pattern formed in the panel bottom member and overlapping with the folding area.
1. A display device comprising:
a display panel including a folding area and a nonfolding area located around the folding area;
a panel bottom member under the display panel and overlapping with the folding area and the nonfolding area; and
a first pattern formed in the panel bottom member and overlapping with the folding area,
wherein the panel bottom member comprises a buffer member and a support member between the display panel and the buffer member, and the first pattern is recessed from a lower surface of the support member.
2. The display device of claim 1 , wherein the first pattern has a groove shape recessed from the lower surface of the support member.
3. The display device of claim 2 , wherein the first pattern has a line shape extending continuously along the folding area.
4. The display device of claim 1 , wherein the first pattern has an uneven shape on the lower surface of the support member.
5. The display device of claim 4 , wherein the first pattern includes a relatively protruded convex portion, and the convex portion is not protruded from the lower surface of the support member.
6. The display device of claim 1 , wherein the support member includes a metal.
7. The display device of claim 6 , wherein an end of the first pattern is aligned with a boundary between the folding area and the nonfolding area.
8. The display device of claim 6 , wherein an end of the first pattern is in the nonfolding area.
9. The display device of claim 1 , further comprising a second pattern formed in the buffer member and overlapping with the first pattern.
10. The display device of claim 1 , wherein an upper surface of the buffer member faces the lower surface of the support member, and
wherein the upper surface of the buffer member overlaps the first pattern.
11. A display device comprising:
a display panel including a folding area and a nonfolding area located around the folding area; and
a panel bottom member under the display panel and comprising a rigid material overlapping with the folding area, the panel bottom member having a first thickness in the folding area and a second thickness in the nonfolding area, the first thickness being thinner than the second thickness.
12. The display device of claim 11 , wherein the panel bottom member includes a buffer member, and a first pattern is formed on an upper surface or a lower surface of the buffer member.
13. The display device of claim 12 , wherein the first pattern has a groove shape recessed from the upper surface or the lower surface of the buffer member.
14. The display device of claim 12 , wherein the first pattern has an uneven shape on the upper surface or the lower surface of the buffer member.
15. The display device of claim 11 ,
wherein
an interval between an upper surface of the panel bottom member and the display panel is constant.
16. The display device of claim 15 , wherein the rigid material includes a metal.
17. The display device of claim 15 , further comprising a buffer member at a lower portion of the panel bottom member.
18. The display device of claim 17 ,
wherein the buffer member has a third thickness in the folding area and a fourth thickness in the nonfolding area, and the third thickness is thinner than the fourth thickness.
19. The display device of claim 18 , wherein the first thickness is thinner than the third thickness.
