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 (28)

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 wiring includes a first main wiring part connected to the controller, and first branch wiring parts connected to the first main wiring part at a first connection point,

the second wiring includes a second main wiring part connected to the controller, and second branch wiring parts connected to the second main wiring part at a second connection point,

the first electrode is connected to the first wiring in a position farther 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,

a number of the first branch wiring parts is greater than a number of the second branch wiring parts, and

the first connection point and the second connection point are each located between the second electrode and the controller.

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.
