Abstract

A display device includes a substrate including a first display area, a second display area, and a non-display area; a first pixel circuit part and a second pixel circuit part disposed in the first display area; a 1-1-th light-emitting element electrically connected to the first pixel circuit part and overlapping the first display area; and a second light-emitting element electrically connected to the second pixel circuit part and overlapping the second display area. The non-display area is disposed between the first display area and the second display area.

Claims (78)

1. A display device comprising:

a substrate including:

a first display area,

a second display area; and

a non-display area;

a first pixel circuit part and a second pixel circuit part disposed in the first display area;

a 1-1-th light-emitting element electrically connected to the first pixel circuit part and overlapping the first display area; and

a second light-emitting element electrically connected to the second pixel circuit part and overlapping the second display area, wherein

the non-display area is disposed between the first display area and the second display area,

the first display area includes a 1-1-th display area and a 1-2-th display area including at least two separate side portions,

the display device includes a scan driver overlapping at least a part of the 1-2-th display area at the two separate side portions,

the display device includes a 1-2-th light-emitting element disposed in the 1-2-th display area, and

the 1-2-th light-emitting element is electrically connected to the second pixel circuit part and disposed on the scan driver.

2. The display device of claim 1 , wherein the non-display area between the first display area and the second display area is a bending area.

3. The display device of claim 1 , wherein the first pixel circuit part and the 1-1-th light-emitting element are disposed in the 1-1-th display area.

4. The display device of claim 3 , wherein

the 1-1-th light-emitting element is electrically connected to the first pixel circuit part.

5. The display device of claim 2 , wherein

the second light-emitting element includes:

a first electrode;

an emission layer disposed on the first electrode; and

a second electrode disposed on the emission layer,

the first electrode is electrically connected to the second pixel circuit part, and

the first electrode is bent in the bending area.

6. The display device of claim 5 , wherein

the display device includes:

a first encapsulation layer disposed on the 1-1-th light-emitting element; and

a second encapsulation layer disposed on the second light-emitting element, and

the first encapsulation layer and the second encapsulation layer are spaced apart.

7. The display device of claim 1 , wherein

the display device includes a scan line extending in a first direction, and

the first display area and the second display area are spaced apart in the first direction.

8. The display device of claim 1 , wherein

the display device includes a data line extending in a second direction, and

the first display area and the second display area are spaced apart in the second direction.

9. The display device of claim 8 , wherein

the display device includes a data driver disposed in the non-display area, and

the first display area, the second display area, and the data driver are disposed in the second direction.

10. The display device of claim 8 , wherein

the display device includes a data driver disposed in the non-display area, and

the second display area, the first display area, and the data driver are disposed in the second direction.

11. The display device of claim 1 , wherein

the first display area is disposed on a front of the display device, and

the second display area is disposed on a rear of the display device.

12. A display device comprising:

a substrate including:

a first display area;

a second display area; and

a bending area between the first display area and the second display area,

a first pixel circuit part and a second pixel circuit part disposed in the first display area;

a 1-1-th light-emitting element electrically connected to the first pixel circuit part and overlapping the first display area; and

a second light-emitting element electrically connected to the second pixel circuit part and overlapping the second display area, wherein

the first display area is disposed on a front of the display device,

the second display area is disposed on a rear of the display device,

the first display area includes a 1-1-th display area and a 1-2-th display area including at least two separate side portions,

the display device includes a scan driver overlapping at least a part of the 1-2-th display area at the two separate side portions,

the display device includes a 1-2-th light-emitting element disposed in the 1-2-th display area and

the 1-2-th light-emitting element is electrically connected to the second pixel circuit part and disposed on the scan driver.

13. The display device of claim 12 , wherein

the 1-1-th light-emitting element is disposed in the 1-1-th display area.

14. The display device of claim 13 , wherein the 1-2-th light-emitting element overlaps the second pixel circuit part.

15. The display device of claim 12 , wherein

the second light-emitting element includes:

a first electrode;

an emission layer overlapping the first electrode; and

a second electrode overlapping the emission layer, and

the first electrode is electrically connected to the second pixel circuit part and intersects the bending area.

16. The display device of claim 12 , wherein

the display device includes:

a first encapsulation layer overlapping the 1-1-th light-emitting element; and

a second encapsulation layer overlapping the second light-emitting element, and

the first encapsulation layer and the second encapsulation layer are spaced apart.

17. The display device of claim 12 , wherein

the display device includes a scan line extending in a first direction, and

the first display area and the second display area are spaced apart in the first direction.

18. The display device of claim 12 , wherein

the display device includes a data line extending in a second direction, and

the first display area and the second display area are spaced apart in the second direction.
