Abstract

According to one embodiment, a display device includes a first electrode, a second electrode, a first wiring electrically connected to the first electrode, a second wiring electrically connected to the second electrode, and a controller electrically connected to the first wiring and the second wiring, wherein the first electrode and the second electrode are located in a display area, the first electrode is connected to the first wiring in a position away from the controller than the second electrode, the second electrode is connected to the second wiring in a position closer to the controller than the first electrode, and a number of the first wiring being greater than a number of the second wiring.

Claims (69)

1. A display device comprising:

a first electrode;

a second electrode spaced from the first electrode;

a first wiring electrically connected to the first electrode;

a second wiring electrically connected to the second electrode; and

a controller electrically connected to the first wiring and the second wiring,

wherein the first electrode and the second electrode are located in a display area,

the first electrode is connected to the first wiring in a position away from the controller than the second electrode,

the second electrode is connected to the second wiring in a position closer to the controller than the first electrode, and

a number of the first wiring is greater than a number of the second wiring.

2. The display device of claim 1 , wherein

a number of contact portions between the first electrode and the first wiring is greater than a number of contact portions between the second electrode and the second wiring.

3. The display device of claim 1 , wherein

the first wiring intersects the first electrode and the second electrode,

the second wiring intersects the second electrode, and does not intersect the first electrode.

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

a first dummy wiring disposed to correspond to the first electrode; and

a second dummy wiring disposed to correspond to the second electrode,

wherein

a number of contact portions between the first electrode and the first dummy wiring is less than a number of contact portions between the second electrode and the second dummy wiring.

5. The display device of claim 4 , further comprising:

a first signal line intersecting the first electrode and the second electrode,

wherein

the first wiring overlaps the first signal line in a plan view.

6. The display device of claim 4 , further comprising:

a second signal line intersecting the first electrode and the second electrode,

wherein

the first dummy wiring and the second wiring overlap the second signal line in a plan view.

7. A display device comprising:

a first electrode;

a second electrode spaced from the first electrode;

a first wiring electrically connected to the first electrode; and

a second wiring electrically connected to the second electrode,

wherein the first electrode and the second electrode are located in a display area,

a wiring length of the first wiring is greater than a wiring length of the second wiring,

the first wiring intersects the first electrode and the second electrode, and

the second wiring intersects the second electrode, and

the second electrode includes an opening overlapping the first wiring in a plan view.

8. The display device of claim 7 , wherein

a number of contact portions between the first electrode and the first wiring is greater than a number of contact portions between the second electrode and the second wiring.

9. The display device of claim 7 , wherein

the opening has a first width,

the first wiring has a second width in a position overlapping the opening in a plan view, and

the second width is less than the first width.

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

a first dummy wiring disposed to correspond to the first electrode; and

a second dummy wiring disposed to correspond to the second electrode,

a number of contact portions between the first electrode and the first dummy wiring is less than a number of contact portions between the second electrode and the second dummy wiring.

11. The display device of claim 10 , further comprising:

a first signal line intersecting the first electrode and the second electrode,

wherein

the first wiring overlaps the first signal line in a plan view.

12. The display device of claim 10 , further comprising:

a second signal line intersecting the first electrode and the second electrode,

wherein

the first dummy wiring and the second wiring overlap the second signal line in a plan view.

13. A display device comprising:

a display area;

a non-display area surrounding the display area;

a controller disposed in the non-display area;

a first wiring and a second wiring electrically connected to the controller and arranged along a first direction in the display area;

a first electrode disposed in the display area; and

a second electrode disposed in the display area, and spaced from the first electrode along a second direction intersecting the first direction,

wherein the second electrode is closer to the controller than the first electrode,

the first electrode intersects the first wiring, and is electrically connected to the first wiring via a contact portion, and

the second electrode intersects the first wiring and the second wiring, and is electrically connected to the second wiring via a contact portion, and

a number of contact portions between the first electrode and the first wiring is greater than a number of contact portions between the second electrode and the second wiring.

14. The display device of claim 13 , wherein

the second electrode does not connect with the first wiring.
