Abstract

A display device includes a substrate including a display area and a non-display area adjacent to the display area, a pixel disposed in the display area, a first voltage line disposed in the non-display area and supplying a first power supply voltage to the pixel, a second voltage line disposed in the non-display area and supplying a second power supply voltage to the pixel, the second voltage line being apart from the first voltage line, and a metallic pattern disposed between the first voltage line and the second voltage line. A shortest distance between the first voltage line and the second voltage line is greater than a width of the metallic pattern.

Claims (41)

1. A display device comprising:

a substrate comprising a display area and a non-display area adjacent to the display area;

a pixel disposed in the display area;

a first voltage line disposed in the non-display area and supplying a first power supply voltage to the pixel;

a second voltage line disposed in the non-display area and supplying a second power supply voltage to the pixel, the second voltage line being apart from the first voltage line; and

a metallic pattern disposed between the first voltage line and the second voltage line so as to reduce an effect caused by external light reflection in the non-display area, wherein

a shortest distance between the first voltage line and the second voltage line is greater than a width of the metallic pattern.

2. The display device of claim 1 , wherein a distance between the first voltage line and the metallic pattern is about 1 μm to about 50 μm.

3. The display device of claim 1 , wherein a distance between the second voltage line and the metallic pattern is about 1 μm to about 50 μm.

4. The display device of claim 1 , wherein

at least part of the first voltage line overlaps a first virtual line parallel with a side of the display area, and

the second voltage line surrounds at least part of the display area.

5. The display device of claim 4 , wherein a width of the first voltage line is less than a width of the second voltage line.

6. The display device of claim 4 , wherein the first voltage line is electrically connected to a first driving voltage line in a first direction in the display area and a second driving voltage line in a second direction crossing the first driving voltage line.

7. The display device of claim 1 , wherein the first voltage line comprises a first lower voltage line and a first upper voltage line on the first lower voltage line.

8. The display device of claim 7 , wherein the metallic pattern and the first lower voltage line or the first upper voltage line are disposed on a same layer.

9. The display device of claim 7 , wherein

the metallic pattern comprises a lower metallic pattern and an upper metallic pattern,

the lower metallic pattern and the first lower voltage line are disposed on a same layer, and

the upper metallic pattern and the first upper voltage line are disposed on a same layer.

10. The display device of claim 7 , wherein the first lower voltage line and the first upper voltage line are electrically connected to each other via a contact hole of an insulating layer between the first lower voltage line and the first upper voltage line.

11. The display device of claim 1 , further comprising a cover film in the non-display area.

12. The display device of claim 11 , wherein the cover film overlaps the first voltage line or the second voltage line.

13. The display device of claim 11 , wherein the cover film is apart from the metallic pattern in a direction in which the cover film is disposed from the display area.

14. The display device of claim 11 , wherein the metallic pattern is disposed between the cover film and the display area.

15. The display device of claim 1 , wherein the first voltage line or the second voltage line comprises holes.

16. A display device comprising:

a substrate comprising a display area and a non-display area adjacent to the display area;

a cover film in the non-display area, the cover film being made of a light-absorbing material:

a pixel disposed in the display area;

a first voltage line disposed between the substrate and the cover film and electrically connected to the pixel, wherein at least part of the first voltage line overlaps a first virtual line parallel with a side of the display area;

a second voltage line disposed between the substrate and the cover film and electrically connected to the pixel, the second voltage line being apart from the first voltage line; and

a metallic pattern disposed between the first voltage line and the second voltage line so as to reduce an effect caused by external light reflection in the non-display area, wherein

the metallic pattern is disposed along the first virtual line, wherein

the metallic pattern is spaced apart from the first voltage line in a plan view, and the metallic pattern is spaced apart from the second voltage line in a plan view.

17. The display device of claim 16 , wherein the metallic pattern is disposed between the display area and the cover film.

18. The display device of claim 16 , wherein a distance between the first voltage line or the second voltage line and the metallic pattern is about 1 μm to about 50 μm.

19. The display device of claim 16 , wherein

the second voltage line extends along outer portions of the display area, and

a width of the first voltage line is less than a width of the second voltage line.

20. The display device of claim 16 , wherein at least one of the first voltage line and the second voltage line includes heat dissipation holes.
