Display device
Provided is a display device, comprising a display panel which comprises a first area and a second area located around the first area; and an under-panel sheet which is located under the display panel and overlaps the first area and the second area, wherein the under-panel sheet comprises a buffer member and a strength reinforcing member, wherein the strength reinforcing member is thinner than the buffer member, and a ratio of a thickness of the buffer member to a thickness of the strength reinforcing member is 3 to 6 times.
1. A display device comprising:
a display panel which comprises a first area and a second area located around the first area; and
an under-panel sheet which is located under the display panel and overlaps the first area and the second area,
wherein the under-panel sheet comprises a buffer member and a strength reinforcing member, wherein the strength reinforcing member is thinner than the buffer member, and a ratio of a thickness of the buffer member to a thickness of the strength reinforcing member is 3 to 6 times.
2. The display device of claim 1 , wherein the first area is generally located in a first plane, and the second area is located in a second plane different from the first plane.
3. The display device of claim 1 , wherein the strength reinforcing member comprises polyimide (PI) or polyethylene terephthalate (PET).
4. The display device of claim 3 , wherein the thickness of the strength reinforcing member is 25 to 50 μm.
5. The display device of claim 3 , wherein the thickness of the buffer member is 100 to 150 μm.
6. The display device of claim 1 , further comprising a first adhesive member which is disposed between the strength reinforcing member and the buffer member.
7. The display device of claim 6 , wherein a thickness of the first adhesive member is 20 to 50 μm.
8. The display device of claim 6 , wherein a ratio of the thickness of the strength reinforcing member to the thickness of the first adhesive member is 1 to 2.5 times.
9. The display device of claim 1 , wherein the under-panel sheet further comprises a heat dissipation member.
10. The display device of claim 9 , further comprising a second adhesive member which is disposed between the heat dissipation member and the strength reinforcing member.
11. The display device of claim 10 , wherein the second adhesive member comprises a thermosetting epoxy or acrylic material.
