Abstract

A display device including a substrate including a bending area arranged between a first area and a second area, the substrate being configured to be bent around a bending axis extending in a first direction, a first inorganic insulating layer disposed on the substrate and having a first opening overlapping the bending area, a first organic layer disposed in the first opening, and a plurality of first conductive layers disposed on the first organic layer and extending from the first area to the second area through the bending area, in which wherein at least one edge of the first organic layer overlapping the first conductive layers includes at least one first short circuit prevention pattern.

First claim

What is claimed is:

1. A display device comprising:
a substrate comprising a bending area arranged between a first area and a second area, the substrate being configured to be bent around a bending axis extending in a first direction;
a first inorganic insulating layer disposed on the substrate and having a first opening overlapping the bending area;
a first organic layer disposed in the first opening; and
a plurality of first conductive layers disposed on the first organic layer and extending from the first area to the second area through the bending area,
wherein at least one edge of the first organic layer overlapping the first conductive layers comprises at least one first short circuit prevention pattern.

2. The display device of claim 1 , wherein:
the first conductive layers are spaced apart from each other in the first direction; and
the at least one first short circuit prevention pattern is disposed between the first conductive layers.

3. The display device of claim 2 , wherein the at least one first short circuit prevention pattern is patterned along a first edge of the first organic layer extending in the first direction.

4. The display device of claim 3 , wherein the at least one first short circuit prevention pattern comprises a recessed portion formed at the first edge of the first organic layer.

5. The display device of claim 4 , wherein:
a first edge area of the first inorganic insulating layer contacts the first opening and at least partially overlaps the first edge area of the first organic layer; and
the at least one first short circuit prevention pattern is disposed in the overlapping area.

6. The display device of claim 3 , wherein the at least one first short circuit prevention pattern comprises a protrusion protruding from the first edge of the first organic layer.

7. The display device of claim 6 , wherein:
a first edge area of the first inorganic insulating layer contacts the first opening and overlaps the first edge area of the first organic layer; and
the at least one first short circuit prevention pattern protrudes from the first edge of the first organic layer in an opposite direction to the first opening.

8. The display device of claim 3 , wherein the at least one first short circuit prevention pattern has at least one of a polygonal pattern, a circular pattern, an elliptic pattern, a zigzag pattern, a wavy pattern, a lattice pattern, and a serrate pattern.

9. The display device of claim 3 , further comprising:
a second organic layer disposed on the first conductive layers; and
a plurality of second conductive layers disposed on the second organic layer and spaced apart from each other in the first direction,
wherein a second edge of the second organic layer comprises at least one second short circuit prevention pattern.

10. The display device of claim 9 , wherein the at least one first short circuit prevention pattern and the at least one second short circuit prevention pattern each comprises a recessed portion formed at the first edge of the first organic layer and the second edge of the second organic layer, respectively.

11. The display device of claim 10 , wherein:
a first edge area of the first inorganic insulating layer contacts the first opening and at least partially overlaps the first edge area of the first organic layer;
the second edge of the second organic layer extends outside the first edge of the first organic layer; and
the at least one first short circuit prevention pattern and the at least one second short circuit prevention pattern are spaced apart from each other in a second direction perpendicular to the first direction.

12. The display device of claim 9 , wherein the at least one first short circuit prevention pattern and the at least one second short circuit prevention pattern each comprises a protrusion protruding from the first edge of the first organic layer and from the second edge of the second organic layer, respectively.

13. The display device of claim 12 , wherein:
a first edge area of the first inorganic insulating layer contacts the first opening and at least partially overlaps the first edge area of the first organic layer;
the second edge of the second organic layer extends outside the first edge of the first organic layer; and
the at least one first short circuit prevention pattern and the at least one second short circuit prevention pattern protrude in an opposite direction to the first opening and are spaced apart from each other in a second direction perpendicular to the first direction.

14. The display device of claim 9 , wherein each of the at least one first short circuit prevention pattern and the at least one second short circuit prevention pattern comprises at least one of a polygonal pattern, a circular pattern, an elliptic pattern, a zigzag pattern, a wavy pattern, a lattice pattern, and a serrate pattern.

15. The display device of claim 9 , wherein the first conductive layers and the second conductive layers overlap each other in a plan view.

16. The display device of claim 9 , wherein the first conductive layers and the second conductive layers are alternately arranged in the first direction.

17. The display device of claim 9 , further comprising:
a thin-film transistor disposed in at least one of the first area and the second area, the thin-film transistor comprising a source electrode, a drain electrode, and a gate electrode; and
a thin film encapsulation layer disposed in the first area,
wherein at least one of the first conductive layers and the second conductive layers are disposed in the same layer as at least one of the source electrode, the drain electrode, and the gate electrode.

18. The display device of claim 17 , wherein at least one of the first conductive layers and the second conductive layers comprise a wiring line connected to a display element.

19. The display device of claim 1 , wherein a width of the first organic layer is greater than a width of the first opening in a second direction perpendicular to the first direction.

20. The display device of claim 1 , wherein the first organic layer covers the first opening.
