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 (34)

1. A display device comprising:

a base;

pixels arrayed in a display area;

a scanning line driver; and

a conductive layer provided outside the display area, wherein

the display area includes a corner edge,

a part of the scanning line driver is provided along the corner edge of the display area,

the conductive layer is provided between the part of the scanning line driver and the corner edge of the display area,

the conductive layer includes a first edge that is a side of the corner edge of the display area,

the conductive layer includes a second edge that is a side of the part of the scanning line driver,

the first edge includes a step shaped pattern along the corner edge of the display area, and

the second edge includes a step shaped pattern along the part of the scanning line driver.

2. The display device of claim 1 , wherein the step shaped pattern of the first edge is a different from the step shaped pattern of the second edge.

3. The display device of claim 2 , further comprising:

video signal lines arrayed in a first direction; and

scanning lines arrayed in a second direction intersecting the first direction in the display area, wherein

the display area includes a third edge along the first direction and a fourth edge along the second direction,

the corner edge is between the third edge and the fourth edge, and

a width of the conductive layer along the corner edge gradually increases from the fourth edge toward the third edge.

4. The display device of claim 3 , wherein the width of the conductive layer is a width between the first edge and the second edge in the first direction.

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

an alignment film that covers the base, wherein

the conductive layer is in contact with the alignment film.

6. The display device of claim 5 , wherein the conductive layer is supplied with a fixed potential.

7. The display device of claim 6 , wherein the fixed potential is VCOMDC.

8. The display device of claim 6 , wherein the fixed potential is a VGL or a VGH.

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

a common electrode provided between the base and the alignment film in the display area, wherein

the conductive layer is separated from the common electrode in plan view.

10. The display device of claim 9 , wherein

the common electrode includes a fifth edge,

the fifth edge of the common electrode faces the first edge of the conductive layer at the corner edge of the display area, and

the fifth edge includes a step shaped pattern.

11. The display device of claim 10 , wherein the step shaped pattern of the fifth edge is similar to the step shaped pattern of the first edge.
