Abstract

A display device with a substrate including an active area having a plurality of pixels, and an inactive area adjacent to the active area; a plurality of power lines in the active area, connected to the plurality of pixels; a first power link line in the inactive area configured to receive power voltage and transmit the power voltage to the plurality of power lines; and a first hole disposed in the first power link line.

Claims (45)

1. A display device, comprising:

a substrate including an active area having a plurality of pixels and an inactive area adjacent to the active area;

a plurality of power lines in the active area, and connected to the plurality of pixels;

a first power link line in the inactive area, and configured to receive a power voltage and transmit the power voltage to the plurality of power lines; and

a first hole in the first power link line,

wherein a width of the first hole along a direction in which the first power link line extends is greater than a width of the first hole along a direction perpendicular to the direction in which the first power link line extends.

2. The display device according to claim 1 , wherein a length of a major axis of the first hole is greater than a length of a minor axis of the first hole, and

wherein the length of the major axis of the first hole extends along a same direction in which the first power link line extends.

3. The display device according to claim 2 , wherein the first hole is located closer to the active area than the inactive area.

4. The display device according to claim 1 , wherein the first hole has one of an oval shape, a dumbbell shape, and a barbell shape.

5. The display device according to claim 1 , further comprising:

at least one additional hole in the first power link line,

wherein the at least one additional hole has a same shape as the first hole and is located at an end of the first power link line.

6. The display device according to claim 1 , wherein the first power link line further includes a mesh line in the first hole.

7. The display device according to claim 1 , wherein the first hole is located closer to a first side of the first power link line and the active area than a second side of the first power link line which is opposite the first side.

8. The display device according to claim 1 , further comprising:

one or more second power link lines disposed in the inactive area and extending from the first power link line in a direction different from a direction in which the first power link line extends,

wherein a location of the first hole corresponds to a location of a corresponding second power link line among the one or more second power link lines.

9. The display device according to claim 8 , wherein a center of the corresponding second power link line and a center of the first hole are located on a same imaginary line.

10. The display device according to claim 8 , wherein a second power link line among the one or more second power link lines is located at a center portion of the inactive area.

11. The display device according to claim 8 , wherein two second power link lines among the one or more second power link lines are located adjacent to opposite edges of the inactive area.

12. The display device according to claim 8 , wherein at least one second power link line among the one or more second power link lines is located between a center portion of the inactive area and an outermost edge of the inactive area.

13. The display device according to claim 12 , wherein the at least one second power link line is equidistant from the center portion of the inactive area and the outermost edge of the inactive area.

14. A display device, comprising:

a substrate including an active area and an inactive area adjacent to the active area;

a plurality of power lines in the active area;

a first power link line disposed in the inactive area and connected to the plurality of power lines; and

a second power link line extending from the first power link line in a direction different than a direction in which the first power link line extends,

wherein the first power link line includes a hole configured to increase a route through which a power voltage travels through from the second power link line to a power line, among the plurality of power lines, positioned closest to the second power link line among the plurality of power lines, and

wherein a mesh line is in the hole, the mesh line having a higher electrical resistance than other adjacent portions of the first power link line.

15. The display device according to claim 14 , wherein the second power link line is perpendicular to the first power link line.

16. The display device according to claim 14 , wherein a center of the hole is disposed between the second power link line and the power line.

17. The display device according to claim 14 , wherein the hole in the first power link line is located closer to the power line than the second power link line and the active area.

18. The display device according to claim 14 , wherein a width of the hole along a direction in which the first power link line extends is greater than a width of the hole along a direction in which the second power link line extends.

19. The display device according to claim 14 , further comprising:

an additional hole at an edge of the hole and the additional hole is configured to reduce static electricity generated at the edge of the hole.

20. A di splay device, comprising:

a substrate including an active area having a plurality of pixels and an inactive area adjacent to the active area;

a plurality of power lines in the active area, and connected to the plurality of pixels;

a first power link line in the inactive area, and configured to receive a power voltage and transmit the power voltage to the plurality of power lines;

a plurality of second power link lines disposed in the inactive area and extending from the first power link line in a direction different from a direction in which the first power link line extends; and

a plurality of holes in the first power link line,

wherein locations of the plurality of holes correspond to locations of the plurality of second power link lines, respectively.

21. The display device according to claim 20 , wherein at least one second power link line among the plurality of second power link lines is located between a center portion of the inactive area and an outermost edge of the inactive area, and

wherein the at least one second power link line is equidistant from the center portion of the inactive area and the outermost edge of the inactive area.
