Abstract

According to one embodiment, a display device includes a first substrate, a second substrate, a sealant, a first electrode, an insulating film and a second electrode. The sealant bonds the first substrate and the second substrate and is provided in a peripheral area surrounding a display area. The first electrode is provided on the first substrate in the peripheral area. The insulating film covers the first electrode. The second electrode is provided on the second substrate in the peripheral area. The sealant contains a conductive member. At least one of the first electrode and the second electrode includes a plurality of fine line portions in an area where the first electrode, the insulating film, the sealant, and the second electrode are overlapped in planar view.

Claims (33)

1. A display device comprising:

a first substrate;

a second substrate arranged opposite to the first substrate;

a sealant which bonds the first substrate and the second substrate and which is provided in a peripheral area surrounding a display area where an image is displayed;

a first electrode provided on the first substrate in the peripheral area;

an insulating film covering the first electrode; and

a second electrode provided on the second substrate in the peripheral area,

the sealant containing a conductive member, wherein

at least one of the first electrode and the second electrode includes a plurality of fine line portions in an area where the first electrode, the insulating film, the sealant, and the second electrode are overlapped in planar view,

the conductive member is a spherical conductive pearl, and

an interval between a first fine line portion included in the plurality of fine line portions and a second fine line portion adjacent to the first fine line portion is larger than a diameter of the conductive pearl.

2. The display device of claim 1 , wherein

the second electrode is electrically connected to a wiring line provided on the first substrate side by the conductive member included in the sealant.

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

a plurality of wiring lines provided on the first substrate and under the first electrode in the peripheral area.

4. The display device of claim 1 , wherein

the second electrode includes the plurality of fine line portions, and

the first electrode does not include the plurality of fine line portions.

5. The display device of claim 1 , wherein

the first electrode includes the plurality of fine line portions, and

the second electrode does not include the plurality of fine line portions.

6. The display device of claim 1 , wherein

the first electrode and the second electrode both include the plurality of fine line portions.

7. The display device of claim 6 , wherein

the plurality of fine line portions of the first electrode and the plurality of fine line portions of the second electrode are not overlapped in planar view.

8. The display device of claim 1 , wherein

the second electrode is a detection electrode.

9. The display device of claim 8 , wherein

the first electrode is a shield electrode having a predetermined fixed potential.

10. The display device of claim 1 , wherein

the first electrode is a detection electrode.

11. The display device of claim 10 , wherein

the second electrode is a shield electrode having a predetermined fixed potential.
