Abstract

According to one embodiment, a display device includes a first substrate, a second substrate opposing the first substrate, a wiring substrate connected to the first substrate, a cover member located on an opposite side to the first substrate so as to interpose the second substrate therebetween and a conductive layer maintained at a predetermined potential, and the first substrate includes an extension portion extending further from the second substrate, the wiring substrate is connected to the extension portion, the cover member includes a first surface opposing the extension portion, and the conductive layer overlaps the extension portion in plan view.

Claims (43)

1. A display device comprising:

a first substrate;

a second substrate opposing the first substrate;

a wiring substrate connected to the first substrate;

a cover member located on an opposite side to the first substrate so as to interpose the second substrate therebetween; and

a conductive layer,

the first substrate comprising an extension portion extending further from the second substrate,

the wiring substrate being connected to the extension portion,

the cover member comprising a first surface opposing the extension portion,

the conductive layer overlapping the extension portion in plan view,

one end of the conductive layer being connected to the first surface of the cover member,

another end of the conductive layer being connected to the wiring substrate.

2. The display device of claim 1 , wherein

the conductive layer being maintained at a predetermined potential.

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

a driver provided in the extension portion,

wherein

the one end of the conductive layer overlaps the driver at least partially in plan view.

4. The display device of claim 3 , wherein

the one end of the conductive layer overlaps the driver entirely in plan view.

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

an insulating layer located between the driver and the conductive layer.

6. The display device of claim 3 , wherein

the driver is mounted on the wiring substrate.

7. The display device of claim 1 , wherein

the conductive layer covers the wiring substrate.

8. The display device of claim 1 , wherein

the wiring substrate further comprises a reference potential member, and

the conductive layer is in contact with the reference potential member.

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

an adhesive layer located between the second substrate and the cover member,

wherein

the conductive layer is in contact with the adhesive layer.

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

an illumination device accommodated in a housing,

wherein

the illumination device is located on an opposite side to the second substrate so as to interpose the first substrate therebetween,

the housing is at a reference potential, and

the conductive layer is electrically connected to the housing.

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

a detection electrode and an outer peripheral wiring line electrically connected to the detection electrode,

wherein

the conductive layer overlaps the outer peripheral wiring line at least partially in plan view.
