Abstract

A display device may include a main flexible printed circuit including a first alignment mark and electrically connected to a first panel; and a touch flexible printed circuit including a second alignment mark and electrically connected to a second panel that is perpendicular to the first panel, wherein the main flexible printed circuit is electrically connected to the touch flexible printed circuit through a pad region, and the touch flexible printed circuit includes a first overcoat region disposed between the first alignment mark and the second alignment mark.

Claims (42)

1. A display device comprising:

a main flexible printed circuit including a first alignment mark, the main flexible printed circuit electrically connected to a first panel; and

a touch flexible printed circuit including a second alignment mark, the touch flexible printed circuit electrically connected to a second panel that is perpendicular to the first panel, wherein

the main flexible printed circuit is electrically connected to the touch flexible printed circuit through a pad region, and

the touch flexible printed circuit includes a first overcoat region disposed between the first alignment mark and the second alignment mark, the first overcoat region being a part of a terminal portion of the touch flexible printed circuit for covering a connector of the main flexible printed circuit.

2. The display device of claim 1 , wherein

the first overcoat region is disposed between the second alignment mark and a first edge of the touch flexible printed circuit.

3. The display device of claim 1 , wherein the touch flexible printed circuit includes:

a first opening that penetrates through the touch flexible printed circuit on an opposite side to the first overcoat region with respect to the second alignment mark; and

a second overcoat region disposed between the second alignment mark and the first opening.

4. The display device of claim 3 , wherein a width of the first overcoat region is greater than a width of the second overcoat region.

5. The display device of claim 3 , wherein a width of the first overcoat region is equal to or less than a width of the second overcoat region.

6. The display device of claim 3 , wherein the first overcoat region and the second overcoat region are disposed below the pad region.

7. The display device of claim 1 , wherein

the main flexible printed circuit includes a third alignment mark, and

the touch flexible printed circuit includes:

a fourth alignment mark; and

a third overcoat region disposed between the third alignment mark and the fourth alignment mark.

8. The display device of claim 7 , wherein the third overcoat region is disposed between the fourth alignment mark and a second edge of the touch flexible printed circuit.

9. The display device of claim 7 , wherein the touch flexible printed circuit includes:

a second opening that penetrates through the touch flexible printed circuit on an opposite side to the third overcoat region with respect to the fourth alignment mark; and

a fourth overcoat region disposed between the fourth alignment mark and the second opening.

10. The display device of claim 9 , wherein a width of the third overcoat region is greater than a width of the fourth overcoat region.

11. The display device of claim 9 , wherein a width of the third overcoat region is equal to or less than a width of the fourth overcoat region.

12. The display device of claim 9 , wherein the third overcoat region and the fourth overcoat region are disposed below the pad region.

13. A display device comprising:

a base film;

a first alignment mark and a second alignment mark disposed on the base film for arrangement with a main flexible printed circuit;

a first overcoat region provided on the base film and disposed between the first alignment mark and a first edge of the base film; and

a second overcoat region disposed between a second edge facing the first edge and the second alignment mark, wherein

the first overcoat region and the second overcoat region are respective parts of a first terminal portion of the touch flexible printed circuit for covering a connector of the main flexible printed circuit.

14. The display device of claim 13 , further comprising:

a first opening that penetrates through the base film on an opposite side to the first overcoat region with respect to the first alignment mark; and

a third overcoat region disposed between the first alignment mark and the first opening.

15. The display device of claim 14 , wherein a width of the first overcoat region is greater than a width of the third overcoat region.

16. The display device of claim 14 , wherein a width of the first overcoat region is equal to or less than a width of the third overcoat region.

17. The display device of claim 13 , further comprising:

a second opening that penetrates through the base film on an opposite side to the second overcoat region with respect to the second alignment mark; and

a fourth overcoat region disposed between the second alignment mark and the second opening.

18. The display device of claim 17 , wherein a width of the second overcoat region is greater than a width of the fourth overcoat region.

19. The display device of claim 17 , wherein a width of the second overcoat region is equal to or less than a width of the fourth overcoat region.

20. The display device of claim 13 , wherein the base film is electrically connected to the main flexible printed circuit through a pad region.
