Abstract

According to one embodiment, a display device includes a first common electrode and a second common electrode arranged in a first direction, a first switch unit selectively supplying a first drive signal or a second drive signal different from the first drive signal to the first common electrode, and a second switch unit selectively supplying the first drive signal or the second drive signal to the second common electrode, wherein the second common electrode and the first switch unit are arranged in a second direction intersecting the first direction, the first switch unit comprises a first switch circuit and a second switch circuit arranged in the second direction.

Claims (27)

1. A display device comprising:

a base;

pixels arrayed in a display area;

a first common electrode in the display area; and

a second common electrode in the display area, wherein

the second common electrode is located next to the first common electrode and is separated from the first common electrode in a first direction,

the display area includes a corner portion,

the first common electrode includes a first edge formed in a step shaped pattern along the corner portion,

the second common electrode includes a second edge formed in a step shaped pattern along the corner portion, and

a length of the step shaped pattern of the first edge is longer than a length of the step shaped pattern of the second edge.

2. The display device of claim 1 , wherein the step shaped pattern of the first edge and the step shaped pattern of the second edge are located outside the display area.

3. The display device of claim 1 , wherein

the first common electrode has a first width that is a maximum width in the first direction,

the second common electrode has a second width that is a maximum width in the first direction, and

the first width is larger than the second width.

4. The display device of claim 1 , wherein the first common electrode and the second common electrode are formed of a transparent conductive material.

5. The display device of claim 1 , wherein a part of the step shaped pattern of the first edge faces a part of the step shaped pattern of the second edge in a second direction intersecting with the first direction.

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

a scanning line driver located outside the display area, wherein

a part of the scanning line driver is provided along the step shaped pattern of the first edge.

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

signal lines; and

a selector circuit connected to the signal lines, wherein

the selector circuit includes selector units, and

a part of the selector units is provided along the step shaped pattern of the second edge.

8. The display device of claim 7 , wherein the part of the selector units is also provided along the step shaped pattern of the first edge.

9. The display device of claim 8 , wherein the part of the selector units is provided between the part of the scanning line driver and the step shaped pattern of the first edge.
