Abstract

A display apparatus includes: a substrate including a display area and a non-display area, where the non-display area includes a first area, a second area, a bent area and a pad area, and the bent area is arranged between the first area and the second area; a display portion arranged in the display area; a driving circuit portion arranged in the non-display area; and a fan-out portion arranged between the display portion and the driving circuit portion and in the first area, the bent area and the second area, where the fan-out portion transfers a data signal from the driving circuit portion to the display portion. The fan-out portion includes a first data line including a first first data line arranged in the second area and a second first data line arranged in the pad area and disposed in a layer different from the first first data line.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate including a display area and a non-display area, wherein the non-display area includes a first area, a second area, a bent area and a pad area, and the bent area is arranged between the first area and the second area;
a display portion arranged in the display area;
a driving circuit portion arranged in the non-display area; and
a fan-out portion arranged between the display portion and the driving circuit portion and in the first area, the bent area and the second area, wherein the fan-out portion transfers a data signal from the driving circuit portion to the display portion,
wherein the fan-out portion includes a first data line including a first first data line and a second first data line, wherein the first first data line is arranged in the second area, and the second first data line is arranged in the pad area and disposed in a layer different from the first first data line.

2. The display apparatus of claim 1 , wherein
the first data line further includes a third first data line arranged in the bent area, and
the third first data line is disposed in a layer different from the second first data line.

3. The display apparatus of claim 1 , wherein the first first data line and the second first data line include different materials from each other.

4. The display apparatus of claim 1 , wherein
the fan-out portion further includes a second data line including a first second data line and a second second data line, the first second data line being arranged in the second area, wherein the second second data line is arranged in the pad area and disposed in a layer different from the first second data line.

5. The display apparatus of claim 4 , wherein the first first data line is disposed in a same layer as the first second data line.

6. The display apparatus of claim 4 , wherein the second first data line and the second second data line are disposed in different layers from each other.

7. The display apparatus of claim 4 , wherein the fan-out portion further includes a first fan-out portion, a second fan-out portion, and a separation area between the first fan-out portion and the second fan-out portion.

8. The display apparatus of claim 7 , wherein the first first data line is electrically connected to the second first data line through a first contact hole defined in the second area.

9. The display apparatus of claim 8 , wherein a position of the first contact hole inside the first fan-out portion is gradually being toward or away from the display portion.

10. The display apparatus of claim 9 , wherein the first second data line is electrically connected to the second second data line through a second contact hole defined in the second area.

11. The display apparatus of claim 10 , wherein, in the second data line and the first data line arranged closest to each other with the separation area therebetween, the second contact hole is closer to the display portion than the first contact hole, wherein the first second data line of the second data line is electrically connected to the second second data line through the second contact hole, and the first first data line of the first data line is electrically connected to the second first data line through the first contact hole.

12. The display apparatus of claim 1 , wherein the display apparatus is foldable around a folding axis.

13. A display apparatus foldable around a folding axis, the display apparatus comprising:
a substrate including a display area and a non-display area, wherein the non-display area includes a first area, a second area, a bent area and a pad area, and the bent area is arranged between the first area and the second area;
a display portion arranged in the display area;
a driving circuit portion arranged in the non-display area; and
a fan-out portion arranged between the display portion and the driving circuit portion and in the first area, the bent area and the second area, wherein the fan-out portion transfers a data signal from the driving circuit portion to the display portion,
wherein the fan-out portion includes a first data line including a first first data line and a second first data line, which are disposed in different layers from each other.

14. The display apparatus of claim 13 , wherein
the first first data line is arranged in the second area, and
the second first data line is arranged in the pad area.
