Flexible circuit board and display device including the same

1. A display device comprising:

a display panel comprising an active area for displaying images on a front surface and a non-active area around the active area; and

a flexible circuit board comprising at least one conductive line extending from one end to an opposite end,

wherein the flexible circuit board is disposed on a rear surface of the display panel to surround more than half of at least a part of the active area to have an opening exposing the active area in a plan view.

2. The display device of claim 1 , further comprising:

a main circuit board disposed in the non-active area of the display panel,

wherein the one end and the opposite end of the flexible circuit board are disposed on the main circuit board such that they are spaced apart from each other.

3. The display device of claim 2 , wherein the main circuit board comprises at least one connection line, and

wherein the at least one conductive line of the flexible circuit board is electrically connected to the at least one connection line of the main circuit board.

4. The display device of claim 3 , wherein the at least one conductive line comprises a plurality of conductive lines and the at least one connection line comprises a plurality of connection lines, and

wherein a single current path is formed by the plurality of conductive lines and the plurality of connection lines.

5. The display device of claim 1 , wherein the flexible circuit board overlaps the non-active area.

6. The display device of claim 5 , wherein the flexible circuit board does not overlap the active area.

7. The display device of claim 1 , further comprising:

a main circuit board disposed in the non-active area of the display panel,

wherein the flexible circuit board comprises a first section closer to the one end and a second section closer to the opposite end, and the one end of the flexible circuit board is disposed on the main circuit board, and the opposite end of the flexible circuit board is connected to the second section of the flexible circuit board.

8. The display device of claim 7 , wherein the flexible circuit board completely surrounds at least a part of the active area.

9. The display device of claim 1 , wherein the flexible circuit board comprises a first area extending in a first direction, a second area extending in a second direction crossing the first direction, and a first corner area located between the first area and the second area to connect them, and

wherein at least two surfaces of the flexible circuit board overlap each other in the first corner area.

10. The display device of claim 9 , wherein the flexible circuit board is bent so that at least a part of one surface of the flexible circuit board faces another part of the one surface of the flexible circuit board in the first corner area.

11. The display device of claim 9 , wherein the flexible circuit board comprises:

a third area extending in a direction opposite to the first direction,

a second corner area disposed between the second area and the third area to connect the second area and the third area,

a fourth area extending in a direction opposite to the second direction,

a third corner area disposed between the third area and the fourth area to connect the third area and the fourth area,

a fifth area extending in the direction opposite to the first direction, and

a fourth corner area disposed between the fourth area and the fifth area to connect the fourth area and the fifth area,

wherein a width of each of the first area, the third area and the fifth area of the flexible circuit board in the second direction is equal to a width of each of the second area and the fourth area in the first direction, and

wherein the flexible circuit board has a loop shape surrounding at least ¾ of the active area.

12. The display device of claim 1 , wherein the flexible circuit board comprises a first subsidiary flexible circuit board and a second subsidiary flexible circuit board, and

wherein each of the first subsidiary flexible circuit board and the second subsidiary flexible circuit board has a loop shape surrounding at least one-fourth of the active area.

13. The display device of claim 12 , wherein the first subsidiary flexible circuit board and the second subsidiary flexible circuit board do not overlap each other in a plan view.

14. The display device of claim 12 , wherein the first subsidiary flexible circuit board and the second subsidiary flexible circuit board partially overlap each other in a plan view.
