Abstract

A display device includes a display panel which includes a display area and a non-display area, a plurality of signal wirings arranged in the display area, a plurality of fanout wirings arranged in the non-display area and electrically connected to the signal wirings, and a plurality of connecting wirings connecting the signal wirings to the fanout wirings, where some of the plurality of fanout wirings intersect and are overlapped with each other in a plan view.

Claims (47)

1. A display device, which comprises a display area and a non-display area, comprising:

a first pixel and a second pixel arranged in the display area;

first to fourth data lines arranged in the display area;

a first main fanout wiring and a second main fanout wiring arranged in the non-display area;

a third main fanout wiring and a fourth main fanout wiring arranged in the non-display area;

a first connecting wiring including a portion disposed in the display area, the first connecting wiring connecting the first data line to the first main fanout wiring; and

a second connecting wiring including a portion disposed in the display area, the second connecting wiring connecting the second data line to the second main fanout wiring,

wherein the third main fanout wiring is electrically connected to the third data line in the non-display area,

wherein the fourth main fanout wiring is electrically connected to the fourth data line in the non-display area,

wherein the third main fanout wiring and the fourth main fanout wiring are not connected any connecting wiring in the display area;

wherein the first pixel and the second pixel each comprise a first subpixel which emits a first color and a second subpixel which emits a second color different from the first color,

wherein the first data line is connected to the first subpixel of the first pixel,

wherein the second data line is connected to the second subpixel of the first pixel,

wherein the third data line is connected to the first subpixel of the second pixel,

wherein the fourth data line is connected to the second subpixel of the second pixel,

wherein the first main fanout wiring and the third main fanout wiring are disposed in a first layer, and

wherein the second main fanout wiring and the fourth main fanout wiring are disposed in a second layer different from the first layer.

2. The display device of claim 1 , wherein the third data line directly contacts the third main fanout wiring in the non-display area, and

wherein the fourth data line directly contacts the fourth main fanout wiring in the non-display area.

3. The display device of claim 1 , wherein the first data line, the second data line, the third data line and the fourth data line are arranged sequentially along a first direction.

4. The display device of claim 2 , wherein the second main fanout wiring, the third main fanout wiring, the fourth main fanout wiring and the first main fanout wiring are arranged sequentially along the first direction.

5. The display device of claim 1 , wherein the first layer and the second layer are arranged alternately along a first direction in the non-display area.

6. The display device of claim 1 , wherein the third main fanout wiring overlaps the second main fanout wiring in the non-display area.

7. The display device of claim 6 , wherein at least one of the third main fanout wiring and the second main fanout wiring comprises a bent portion in a plan view.

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

first to fourth sub fanout wirings disposed in the non-display area,

wherein the first to fourth sub fanout wirings are spaced apart from and electrically connected to the first to fourth main fanout wirings, respectively.

9. The display device of claim 8 ,

wherein the first sub fanout wiring and the third sub fanout wiring are disposed in the first layer, and

wherein the second sub fanout wiring and the fourth sub fanout wiring are disposed in the second layer.

10. The display device of claim 8 , further comprising:

a first bent fanout wiring which connects the first main fanout wiring and the first sub fanout wiring;

a second bent fanout wiring which connects the second main fanout wiring and the second sub fanout wiring;

a third bent fanout wiring which connects the third main fanout wiring and the third sub fanout wiring; and

a fourth bent fanout wiring which connects the fourth main fanout wiring and the fourth sub fanout wiring.

11. The display device of claim 10 , wherein the first bent fanout wiring, the second bent fanout wiring, the third bent fanout wiring and the fourth bent fanout wiring are disposed in a third layer different from the first layer and the second layer.

12. The display device of claim 11 , wherein the first connecting wiring and the second connecting wiring are disposed in the third layer.

13. The display device of claim 1 , wherein the first pixel and the second pixel each further comprise a third subpixel which emits a third color different from the first color and the second color,

wherein the first data line is connected to the third subpixel of the first pixel, and

wherein the third data line is connected to the third subpixel of the second pixel.

14. The display device of claim 13 , wherein the first data line and the third data line are not connected any subpixel which emits the second color, and

wherein the second data line and the fourth data line are not connected any subpixel which emits the first color or the third color.

15. The display device of claim 1 , wherein the first connecting wiring and the second connecting wiring are disposed in a third layer different from the first layer and the second layer, and

wherein the first data line, the second data line, the third data line and the fourth data line are disposed in a fourth layer different from the first layer, the second layer and the third layer.

16. The display device of claim 1 , wherein the first connecting wiring overlaps the second data line, the third data line and the fourth data line in the display area.

17. The display device of claim 16 , wherein the second connecting wiring overlaps the third data line in the display area.

18. The display device of claim 17 , wherein the second connecting wiring does not overlap the first data line and the fourth data line in the display area.
