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 (27)

1. A display device comprising:

scanning lines extending in a first direction;

a first signal line and a second signal line extending in a second direction crossing the first direction;

a first metal wiring overlapping the first signal line and a second metal wiring overlapping the second signal line;

a first pixel electrode and a second pixel electrode arranged along the second direction;

a common electrode including a first electrode opposed to the first pixel electrode and a second electrode opposed to the second pixel electrode; and

a controller which supplies signals to the first and second signal lines and the first and second metal wirings, wherein

the second electrode is separated from the first electrode in the second direction and is closer to the controller than the first electrode,

the first metal wiring overlaps the first electrode and the second electrode in a plan view and is connected to the first electrode via first contact portions,

the second metal wiring overlaps the second electrode in the plan view and is connected to the second electrode via second contact portions, and

a number of the first contact portions is different from a number of the second contact portions.

2. The display device of claim 1 , wherein

the second wiring does not overlap the first electrode.

3. The display device of claim 1 , wherein

the second electrode is not connected to the first metal wiring.

4. The display device of claim 1 , wherein

the number of the first contact portions is greater than the number of the second contact portions.

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

a first dummy wiring overlapping the first electrode in the plan view; and

a second dummy wiring overlapping the second electrode in the plan view,

wherein

a number of contact portions between the first electrode and the first dummy wiring is different from a number of contact portions between the second electrode and the second dummy wiring.

6. The display device of claim 5 , wherein

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

7. The display device of claim 5 , wherein

the first dummy wiring overlaps the second signal line, and

the first dummy wiring is separated from the second metal wiring.
