Abstract

Provided is a display apparatus capable of reducing generation of defects such as a disconnection during manufacturing processes, while ensuring longer lifespan thereof. The display apparatus includes: a substrate including a bending area between a first area and a second area to be bent in the bending area about a bending axis, the substrate including a first substrate and a second substrate that are stacked; a first intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate; and a first upper line over the second substrate to be electrically connected to the first intermediate line via a first contact hole in the second substrate.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate comprising a bending area between a first area and a second area to be bent in the bending area about a bending axis, the substrate comprising a first substrate and a second substrate that are stacked;
a first intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate;
a first upper line located in the first area and comprising an end portion facing the second area, the first upper line over the second substrate to be electrically connected to the first intermediate line via a first contact hole in the second substrate, the first contact hole being located in the first area; and
a first additional line at least partially located in the second area and comprising an end portion facing the first area, the first additional line over the second substrate to be electrically connected to the first intermediate line via a first additional contact hole in the second substrate, the first additional contact hole being located in the second area.

2. The display apparatus of claim 1 , wherein the first upper line is at least partially located in the first area.

3. The display apparatus of claim 1 , further comprising:
a second intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate; and
a second upper line over the second substrate to be electrically connected to the second intermediate line via a second contact hole in the second substrate.

4. The display apparatus of claim 1 , wherein a portion of the first intermediate line, which corresponds to the first additional contact hole, has a width that is greater than a width of the other portion of the first intermediate line.

5. The display apparatus of claim 1 , further comprising:
a second intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate; and
a second additional line over the second substrate to be electrically connected to the second intermediate line via a second additional contact hole in the second substrate.

6. The display apparatus of claim 5 , wherein, in the first intermediate line, a portion overlapping the first additional contact hole has a width that is greater than a width of the other portion of the first intermediate line, and in the second intermediate line, a portion overlapping the second additional contact hole has a width that is greater than a width of the other portion of the second intermediate line, and
wherein the portion of the first intermediate line overlapping the first additional contact hole and the portion of the second intermediate line overlapping the second additional contact hole are not adjacent to each other in a direction crossing a direction in which the first intermediate line and the second intermediate line extend.

7. The display apparatus of claim 5 , wherein the portion of the first intermediate line overlapping the first additional contact hole and the portion of the second intermediate line overlapping the second additional contact hole are not adjacent to each other in a direction crossing a direction in which the first intermediate line and the second intermediate line extend.

8. The display apparatus of claim 1 , wherein the first area comprises a display area, and an end portion of the first intermediate line in a direction towards the display area is closer to the display area than the first contact hole.

9. The display apparatus of claim 1 , wherein a portion of the first intermediate line overlapping the first contact hole has a width that is greater than a width of the other portion of the first intermediate line.

10. The display apparatus of claim 1 , wherein the first area comprises a display area, and the first upper line is electrically connected to a display device located in the display area.

11. The display apparatus of claim 1 , wherein the first area comprises a display area, and the display area is throughout the first area, the bending area, and the second area.

12. A display apparatus comprising:
a substrate comprising a bending area between a first area and a second area to be bent in the bending area about a bending axis, the substrate comprising a first substrate and a second substrate that are stacked;
a first intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate;
a first upper line over the second substrate to be electrically connected to the first intermediate line via a first contact hole in the second substrate;
a second intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate; and
a second upper line over the second substrate to be electrically connected to the second intermediate line via a second contact hole in the second substrate,
wherein the portion of the first intermediate line overlapping the first contact hole and the portion of the second intermediate line overlapping the second contact hole are not adjacent to each other in a lateral direction, the lateral direction being parallel to the substrate and crossing a direction in which the first intermediate line and the second intermediate line extend.

13. The display apparatus of claim 12 , wherein, when viewed in a direction perpendicular to the substrate, in the first intermediate line, a portion overlapping the first contact hole has a width that is greater than a width of the other portion of the first intermediate line, and in the second intermediate line, a portion overlapping the second contact hole has a width that is greater than a width of the other portion of the second intermediate line.

14. A display apparatus comprising:
a substrate comprising a bending area between a first area and a second area to be bent in the bending area about a bending axis, the substrate comprising a first substrate and a second substrate that are stacked;
a first intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate;
a first upper line over the second substrate to be electrically connected to the first intermediate line via a first contact hole in the second substrate; and
a first additional line at least partially located in the second area, the first additional line over the first substrate being electrically connected to the first intermediate line via a first additional contact hole in the first substrate.

15. The display apparatus of claim 14 , wherein the first additional contact hole is located to correspond to an upper surface of the first additional line and within the upper surface of the first additional line.

16. The display apparatus of claim 14 , wherein the portion of the first additional line overlaps the first additional contact hole and has a width that is greater than a width of the other portion of the first additional line.

17. The display apparatus of claim 14 , further comprising:
a second intermediate line at least partially located in the bending area, and located between the first substrate and the second substrate; and
a second additional line over the first substrate to be electrically connected to the second intermediate line via a second additional contact hole in the first substrate.

18. The display apparatus of claim 17 , wherein, in the first additional line, a portion overlapping the first additional contact hole has a width that
