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 (42)

1. A display device comprising:

common electrodes arrayed in a first direction; and

a sealing member outside a display area,

wherein

the common electrodes include a first common electrode and a second common electrode next to the first common electrode in the first direction,

the first common electrode is between the sealing member and the second common electrode in the first direction,

the first common electrode includes a first edge and a second edge opposed to the first edge in the first direction,

the second common electrode includes a first edge and a second edge opposed to the first edge of the second common electrode in the first direction,

the first edge of the first common electrode faces the sealing member,

the first edge of the second common electrode faces the second edge of the first common electrode,

the first edge of the first common electrode is located between the sealing member and the display area,

a part of the second edge of the first common electrode is located between the sealing member and the display area,

a part of the first edge of the second common electrode is located between the sealing member and the display area, and

the part of the first edge of the second common electrode faces the part of the second edge of the first common electrodes in a second direction intersecting the first direction.

2. The display device of claim 1 , wherein

the part of the second edge of the first common electrode includes a step portion formed in a step shape,

the part of the first edge of the second common electrode includes a step portion formed in a step shape, and

the step portion of the first common electrode faces the step portion of the second common electrode in the second direction.

3. The display device of claim 2 , wherein

a part of the sealing material includes a curved portion formed in a curved shape, and

the step portion of the first common electrode extends along the curved portion of the sealing material.

4. A display device comprising:

common electrodes arrayed in a first direction; and

a sealing member outside a display area,

wherein

the common electrodes include a first common electrode and a second common electrode next to the first common electrode,

the first common electrode is between the sealing member and the second common electrode,

the first common electrode includes a first edge and a second edge opposed to the first edge,

the second common electrode includes a first edge and a second edge opposed to the first edge of the second common electrode,

the first edge of the first common electrode faces the sealing member,

the first edge of the second common electrode faces the second edge of the first common electrode,

the first edge of the first common electrode is located between the sealing member and the display area,

a part of the first edge of the first common electrode is formed in a step shape, and

a part of the second edge of the first common electrode is formed in a step shape between the sealing member and the display area.

5. The display device of claim 4 , wherein

a part of the first edge of the second common electrode is formed in a step shape, and

the part of the second edge of the first common electrode faces the part of the first edge of the second common electrode in a second direction intersecting the first direction.

6. The display device of claim 5 , wherein

a part of the sealing material includes a curved portion formed in a curved shape,

the part of the first edge of the first common electrode extends along the curved portion of the sealing material,

the part of the second edge of the first common electrode extends along the curved portion of the sealing material, and
