Abstract

A display device includes a substrate including a display area and a peripheral area outside the display area, where the peripheral area includes a bending area and the bending area bent around a bending axis; an inorganic material layer disposed on the substrate and having a trench corresponding to the bending area and; a construction member disposed in the trench of the inorganic material layer; a first organic material layer covering the construction member; and a conductive layer disposed on the first organic material layer.

Claims (35)

1. A display device comprising:

a substrate comprising a display area and a peripheral area outside the display area, wherein the peripheral area comprises a bending area bent around a bending axis;

an inorganic material layer disposed on the substrate and having a trench corresponding to the bending area;

a construction member disposed in the trench of the inorganic material layer;

a first organic material layer directly covering the construction member; and

a conductive layer disposed on the first organic material layer,

wherein the construction member is insulated from the conductive layer.

2. The display device of claim 1 , wherein the construction member has a board shape corresponding to the trench of the inorganic material layer.

3. The display device of claim 1 , wherein the construction member comprises a plurality of patterns, each having a line shape extending in a first direction parallel to the bending axis and apart from each other in a second direction perpendicular to the first direction.

4. The display device of claim 1 , wherein the construction member comprises a plurality of patterns, each having a line shape extending in a second direction perpendicular to a first direction parallel to the bending axis and apart from each other in the first direction.

5. The display device of claim 1 , wherein the construction member comprises a plurality of patterns apart from each other in a first direction parallel to the bending axis and apart from each other in a second direction perpendicular to the first direction.

6. The display device of claim 1 , wherein

the construction member comprises a same material as a data line disposed in the display area, and

the conductive layer comprises a same material as a power supply voltage line disposed in the display area.

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

a second conductive layer and a third conductive layer, which are disposed on the inorganic material layer in the peripheral area and separated from each other by the trench of the inorganic material layer.

8. The display device of claim 7 , wherein the conductive layer is connected to the second conductive layer and the third conductive layer.

9. The display device of claim 1 , wherein an upper surface of the first organic material layer has a concave-and-convex shape.

10. The display device of claim 1 , wherein upper and bottom surfaces of the conductive layer have concave-and-convex shapes.

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

a second organic material layer covering the conductive layer.

12. A display device comprising:

a substrate comprising a first area in which a pixel is disposed, a second area in which a driving unit is disposed, and a bending area between the first area and the second area;

an inorganic material layer disposed on the substrate in the bending area;

a construction member disposed on the inorganic material layer;

a first organic material layer directly covering the construction member; and

a conductive layer disposed on the first organic material layer and extending from the first area to the second area through the bending area.

13. The display device of claim 12 , wherein the construction member has a board shape corresponding to the bending area.

14. The display device of claim 12 , wherein the construction member extends in a second direction perpendicular to a first direction, in which the conductive layer extends, and comprises a plurality of patterns apart from each other in the first direction.

15. The display device of claim 12 , wherein the construction member extends in a first direction, in which the conductive layer extends, and comprises a plurality of patterns apart from each other in a second direction perpendicular to the first direction.

16. The display device of claim 12 , wherein the construction member comprises a plurality of patterns apart from each other in a first direction, in which the conductive layer extends, and apart from each other in a second direction perpendicular to the first direction.

17. The display device of claim 12 , wherein an upper surface of the first organic material layer has a concave-and-convex shape.

18. The display device of claim 12 , wherein upper and bottom surfaces of the conductive layer have concave-and-convex shapes.

19. The display device of claim 12 , further comprising:

a second organic material layer covering the conductive layer.
