6. The flexible display apparatus of claim 1 , wherein the first wiring and the second wiring are not arranged in the third area.
7. The flexible display apparatus of claim 1 , further comprising a display unit arranged in the first area, and a driver arranged in the second area.
8. The flexible display apparatus of claim 1 , wherein the conductive layer electrically connecting the first wiring and the second wiring is arranged between the first area and the second area.
9. The flexible display apparatus of claim 1 , wherein the third area comprises a 3-1 surface facing an outside of the flexible substrate and a 3-2 surface facing an inside of the flexible substrate, and the conductive layer comprises a metal layer arranged on the 3-2 surface.
10. The flexible display apparatus of claim 9 , wherein the metal layer is in contact with the first hole and electrically connected to the first wiring, and is in contact with the second hole and electrically connected to the second wiring.
11. The flexible display apparatus of claim 1 , wherein the first area comprises a 1-1 surface having the first wiring arranged thereon and a 1-2 surface arranged on a side of the first area opposite the 1-1 surface, the second area comprises a 2-1 surface having the second wiring arranged thereon and a 2-2 surface arranged on a side of the second area opposite the 2-1 surface, and the 1-2 surface and the 2-2 surface face each other.
12. The flexible display apparatus of claim 11 , wherein at least a portion of the 1-2 surface and the 2-2 surface are in surface-contact with each other.
13. A method of manufacturing a flexible display apparatus, the method comprising:
preparing a flexible substrate including a first area, a second area, and a third area between the first area and the second area;
forming a first hole penetrating completely through the flexible substrate in the first area;
forming a second hole penetrating completely through the flexible substrate in the second area;
forming a first wiring to cover the first hole on the first area;
forming a second wiring to cover the second hole on the second area; and
bending the third area, wherein the first wiring and the second wiring are electrically connected with each other via the first hole and the second hole, and wherein the first wiring and the second wiring are each in direct contact with a conductive layer therebetween or in direct contact with each other.
14. The method of claim 13 , wherein the forming the first wiring comprises embedding at least a portion of the first wiring in the first hole, and the forming the second wiring comprises embedding at least a portion of the second wiring in the second hole.
15. The method of claim 13 , further comprising forming an inorganic layer on the flexible substrate, wherein the inorganic layer is formed on the flexible substrate excluding the third area.
16. The method of claim 13 , wherein the first wiring and the second wiring are not formed on the flexible substrate in the third area.
17. The method of claim 13 , further comprising forming the conductive layer electrically connecting the first wiring and the second wiring between the first area and the second area.
18. The method of claim 13 , wherein the first area comprises a 1-1 surface having the first wiring arranged thereon and a 1-2 surface arranged on a side of the first area opposite the 1-1 surface, the second area comprises a 2-1 surface having the second wiring arranged thereon and a 2-2 surface arranged on a side of the second area opposite the 2-1 surface, and the 1-2 surface and the 2-2 surface face each other.
