Abstract

A display device comprises a first substrate including a first top portion, a first sidewall portion and a first bent portion, a second substrate including a second top portion, a second sidewall portion and a second bent portion, a display element and a packaging material. The first bent portion is disposed between the first top portion and the first sidewall portion. The second substrate is separated from the first substrate by a predetermined distance to form an accommodating space. The second top portion is disposed corresponding to the first top portion. The second bent portion is disposed between the second top portion and the second sidewall portion. The display element is disposed in the accommodating space. The packaging material is disposed in the accommodating space and corresponding to the first sidewall portion and the second sidewall portion.

First claim

What is claimed is:

1. A display device, comprising:
a first substrate including:
a first top portion;
a first sidewall portion;
a first bent portion extended from an edge of the first top portion and disposed between and connecting the first top portion and the first sidewall portion; and
a first extension portion connected to the first sidewall portion;

a second substrate separated from the first substrate by a predetermined distance to form an accommodating space and including:
a second top portion disposed corresponding to the first top portion;
a second sidewall portion;
a second bent portion extended from an edge of the second top portion and disposed between and connecting the second top portion and the second sidewall portion; and
a second extension portion connected to the second sidewall portion and disposed corresponding to the first extension portion, wherein the first extension portion and the second extension portion are extended along a direction parallel to the first top portion;

a display element disposed in the accommodating space;
a packaging material disposed in the accommodating space and corresponding to the first sidewall portion and the second sidewall portion;
a third bent portion extended from the first sidewall portion and disposed between the first sidewall portion and the first extension portion; and
a fourth bent portion extended from the second sidewall portion and disposed between the second sidewall portion and the second extension portion;
wherein the first extension portion is extended to another edge of the first top portion, and the second extension portion is extended to another edge of the second top portion;
wherein the packaging material includes a first packaging material and a second packaging material, the extensibility of the first packaging material is greater than that of the second packaging material, the first packaging material is disposed in the accommodating space and corresponding to the first bent portion, the first sidewall portion, the third bent portion, the second bent portion, the second sidewall portion and the fourth bent portion, and the second packaging material is disposed in the accommodating space and corresponding to the first extension portion and the second extension portion.

2. The display device as recited in claim 1 , wherein the packaging material is disposed around the display element.

3. The display device as recited in claim 1 , wherein the length of the second sidewall portion is in a range between 1 mm and 20 mm.

4. The display device as recited in claim 1 , wherein the first top portion and the second top portion are curved structures.

5. The display device as recited in claim 4 , wherein the curvature radiuses of the first top portion and second top portion are in a range between 10 mm and 1000 mm.

6. A display device, comprising:
a first substrate including:
a first top portion;
a first sidewall portion;
a first bent portion extended from an edge of the first top portion and disposed between and connecting the first top portion and the first sidewall portion; and
a first extension portion connected to the first sidewall portion;

a second substrate separated from the first substrate by a predetermined distance to form an accommodating space and including:
a second top portion disposed corresponding to the first top portion;
a second sidewall portion;
a second bent portion extended from an edge of the second top portion and disposed between and connecting the second top portion and the second sidewall portion; and
a second extension portion connected to the second sidewall portion and disposed corresponding to the first extension portion, wherein the first extension portion and the second extension portion are extended along a direction parallel to the first top portion;

a display element disposed in the accommodating space;
a packaging material disposed in the accommodating space and corresponding to the first sidewall portion and the second sidewall portion;
a third bent portion extended from the first sidewall portion;
a fourth bent portion extended from the second sidewall portion;
a fifth bent portion extended from the third bent portion; and
a sixth bent portion extended from the fourth bent portion;
wherein the third bent portion and the fifth bent portion are disposed between the first sidewall portion and the first extension portion, and the fourth bent portion and the sixth bent portion are disposed between the second sidewall portion and the second extension portion.

7. The display device as recited in claim 6 , wherein the packaging material is disposed around the display element.

8. The display device as recited in claim 6 , wherein the first extension portion is extended to another edge of the first top portion, and the second extension portion is extended to another edge of the second top portion.

9. The display device as recited in claim 8 , wherein the length of the second sidewall portion is in a range between 1 mm and 20 mm.

10. The display device as recited in claim 6 , wherein the first top portion and the second top portion are curved structures.

11. The display device as recited in claim 10 , wherein the curvature radiuses of the first top portion and second top portion are in a range between 10 mm and 1000 mm.
