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 (34)

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 common electrode including a first electrode and a second electrode separated from the first electrode; and

a controller supplying signals to the signal lines and the metal wirings;

wherein

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

the first electrode and the second electrode include openings overlapping the first metal wiring and the second metal wiring,

the first metal wiring is connected to the first electrode via first contact portions,

the second metal wiring is connected to the second electrode via second contact portions,

the first metal wiring and the second metal wiring each have a first end which is connected to the controller and a second end opposite to the first end,

the first contact portions are located closer to the controller than the second end of the first metal wiring, and

the second contact portions are located closer to the controller than the second end of the second metal wiring.

2. The display device of claim 1 , wherein

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

3. The display device of claim 2 , wherein

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

4. The display device of claim 1 , wherein

the second end of the second metal wiring is located closer to the controller than the second end of the first metal wiring.

5. The display device of claim 1 , wherein

the second metal wiring does not overlap with the first electrode.

6. The display device of claim 1 , wherein

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

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

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

a second dummy wiring overlapping with 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.

8. The display device of claim 7 , 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.

9. The display device of claim 7 , wherein

the first dummy wiring overlaps with the second signal line, and

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