Abstract

Provided is a display apparatus which may reduce or minimize the occurrence of a defect due to an external shock while improving an expected lifespan thereof. The display apparatus includes a substrate having a first area, a second area, and a bending area between the first area and the second area, and being configured to be bent around a bending axis extending in a first direction, an inorganic insulating portion on the bending area, having a width along an edge of the substrate, and including a plurality of dams defining a plurality of grooves, and a first organic layer on the bending area, and partially overlapping the inorganic insulating portion to cover at least some of the dams.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate having:
a first area;
a second area; and
a bending area between the first area and the second area, and being configured to be bent around a bending axis extending in a first direction;

an inorganic insulating portion on the bending area, having a width along an edge of the substrate, and comprising a plurality of dams defining a plurality of grooves; and
a first organic layer on the bending area, and partially overlapping the inorganic insulating portion to cover at least some of the dams.

2. The display apparatus of claim 1 , wherein at least a portion of the first organic layer is filled in the plurality of grooves.

3. The display apparatus of claim 1 , wherein the inorganic insulating portion comprises:
a first insulating layer on the substrate; and
a second insulating layer on the first insulating layer.

4. The display apparatus of claim 3 , wherein the plurality of grooves penetrate the second insulating layer.

5. The display apparatus of claim 4 , wherein the plurality of grooves expose at least a portion of the first insulating layer.

6. The display apparatus of claim 3 , wherein the plurality of grooves penetrate the first insulating layer and the second insulating layer.

7. The display apparatus of claim 6 , wherein the plurality of grooves expose at least a portion of the substrate.

8. The display apparatus of claim 1 , further comprising a first wiring portion on the first organic layer.

9. The display apparatus of claim 8 , further comprising a second organic layer on the first organic layer.

10. The display apparatus of claim 9 , further comprising a second wiring portion on the second organic layer.

11. The display apparatus of claim 10 , wherein the first wiring portion and the second wiring portion do not overlap each other.

12. The display apparatus of claim 1 , wherein the bending area comprises:
an edge area having a width along the edge of the substrate; and
a wiring area at a side of the edge area, and
wherein the inorganic insulating portion is on the edge area outside of the wiring area.

13. The display apparatus of claim 12 , wherein the first organic layer is on the wiring area and is on at least a portion of the edge area.

14. The display apparatus of claim 1 , wherein the plurality of dams are located over an entire surface of the inorganic insulating portion.

15. The display apparatus of claim 14 , wherein the first organic layer covers all or some of the plurality of dams.

16. The display apparatus of claim 1 , wherein the plurality of dams are located over a portion of the inorganic insulating portion.

17. The display apparatus of claim 16 , wherein the first organic layer covers all or some of the plurality of dams.

18. The display apparatus of claim 1 , further comprising:
a display unit on the first area of the substrate; and
a panel driver unit on the second area of the substrate.
