Abstract

A display device includes a main light emitting part, a first sub-light emitting part spaced apart from the main light emitting part in a first direction, a main pixel circuit connected to the main light emitting part, and overlapping at least a portion of the main light emitting part, a first sub-pixel circuit, without overlapping the first sub-light emitting part, connected to the first sub-light emitting part, and spaced apart from the first sub-light emitting part in a second direction that is perpendicular to the first direction, a main data line extending in the first direction, and connected to the main pixel circuit, a first sub-data line extending in the first direction, and connected to the first sub-pixel circuit, and a first bridge line connecting the main data line to the first sub-data line.

Claims (65)

1. A display device comprising:

a main light emitting part;

a first sub-light emitting part spaced apart from the main light emitting part in a first direction;

a main pixel circuit connected to the main light emitting part, and overlapping at least a portion of the main light emitting part;

a first sub-pixel circuit, without overlapping the first sub-light emitting part, connected to the first sub-light emitting part, and spaced apart from the first sub-light emitting part in a second direction that is perpendicular to the first direction, wherein the first direction and the second direction extend along a same plane;

a main data line extending in the first direction, and connected to the main pixel circuit;

a first sub-data line extending in the first direction, and connected to the first sub-pixel circuit; and

a first bridge line connecting the main data line to the first sub-data line.

2. The display device of claim 1 ,

wherein the first bridge line includes:

a first vertical bridge line connected to the main data line, and extending in the first direction; and

a first horizontal bridge line connecting the first vertical bridge line to the first sub-data line, and extending in the second direction.

3. The display device of claim 2 ,

wherein a portion of the first vertical bridge line overlaps the main pixel circuit.

4. The display device of claim 1 ,

wherein a portion of the main data line overlaps the main pixel circuit, and

wherein a portion of the first sub-data line overlaps the first sub-pixel circuit.

5. The display device of claim 4 ,

wherein a first distance from the main light emitting part to the main data line is smaller than a second distance from the first sub-light emitting part to the first sub-data line.

6. The display device of claim 1 ,

wherein a same data voltage is applied to the main data line and the first sub-data line.

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

a second sub-light emitting part spaced apart from the first sub-light emitting part in the first direction;

a second sub-pixel circuit, without overlapping the second sub-light emitting part, connected to the second sub-light emitting part, and spaced apart from the second sub-light emitting part in the second direction;

a second sub-data line extending in the first direction, and connected to the second sub-pixel circuit; and

a second bridge line connecting the first sub-data line to the second sub-data line.

8. The display device of claim 7 ,

wherein the second bridge line extends in the second direction, and is connected to each of the first sub-data line and the second sub-data line.

9. The display device of claim 7 ,

wherein a same data voltage is applied to the main data line, the first sub-data line, and the second sub-data line.

10. The display device of claim 7 ,

wherein a second distance from the first sub-light emitting part to the first sub-data line is smaller than a third distance from the second sub-light emitting part to the second sub-data line.

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

a third sub-pixel circuit overlapping at least a portion of the first sub-light emitting part;

a third sub-light emitting part, without overlapping the third sub-pixel circuit, connected to the third sub-pixel circuit, and spaced apart from the first sub-light emitting part in a third direction that is opposite to the second direction; and

a third sub-data line extending in the first direction, and connected to the third sub-pixel circuit.

12. The display device of claim 11 ,

wherein the third sub-data line is spaced apart from the main data line in the first direction.

13. The display device of claim 11 ,

wherein a first data voltage is applied to the first sub-data line, and

wherein a second data voltage that is different from the first data voltage is applied to the third sub-data line.

14. The display device of claim 11 ,

wherein a portion of the third sub-data line overlaps the third sub-pixel circuit.

15. A display device comprising:

a first sub-light emitting part;

a second sub-light emitting part spaced apart from the first sub-light emitting part in a first direction;

a first sub-pixel circuit, without overlapping the first sub-light emitting part, connected to the first sub-light emitting part, and spaced apart from the first sub-light emitting part in a second direction that is perpendicular to the first direction;

a second sub-pixel circuit, without overlapping the second sub-light emitting part, connected to the second sub-light emitting part, and spaced apart from the second sub-light emitting part in the second direction;

a first sub-data line extending in the first direction, and connected to the first sub-pixel circuit;

a second sub-data line extending in the first direction, and connected to the second sub-pixel circuit; and

a first bridge line connecting the first sub-data line to the second sub-data line.

16. The display device of claim 15 ,

wherein the first sub-light emitting part does not overlap the first sub-pixel circuit.

17. The display device of claim 15 ,

wherein a portion of the first sub-data line overlaps the first sub-pixel circuit, and

wherein a portion of the second sub-data line overlaps the second sub-pixel circuit.

18. The display device of claim 17 ,

wherein a first distance from the first sub-light emitting part to the first sub-data line is smaller than a second distance from the second sub-light emitting part to the second sub-data line.

19. The display device of claim 15 , further comprising:

a third sub-light emitting part spaced apart from the second sub-light emitting part in the first direction;

a third sub-pixel circuit, without overlapping the third sub-light emitting part, connected to the third sub-light emitting part, and spaced apart from the third sub-light emitting part in the second direction;

a third sub-data line extending in the first direction, and connected to the third sub-pixel circuit; and

a second bridge line connecting the second sub-data line to the third sub-data line.

20. The display device of claim 19 ,

wherein a second distance from the second sub-light emitting part to the second sub-data line is smaller than a third distance from the third sub-light emitting part to the third sub-data line.
