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 (33)

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 maintained at a predetermined potential, 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 directly overlapping the extension portion in plan view and opposing the extension portion, the conductive layer overlapping the extension portion in plan view, and the conductive layer contacting an adhesive layer between the cover member and the second substrate, a driver provided in the extension portion, wherein the conductive layer overlaps the driver at least partially in plan view.

2. The device of claim 1 , wherein the conductive layer overlaps the driver entirely in plan view.

3. The device of claim 1 , further comprising: an insulating layer located between the driver and the conductive layer.

4. The device of claim 1 , wherein

the conductive layer comprises a first end portion in contact with the first surface and a second end portion on an opposite side to the first end portion, and

the first substrate is located between the first end portion and the second end portion.

5. The device of claim 1 , wherein

the conductive layer covers the wiring substrate.

6. The device of claim 4 , wherein

the wiring substrate further comprises a reference potential member, and

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

7. The device of claim 1 , further comprising:

an illumination unit accommodated in a housing,

wherein

the illumination unit 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.

8. The device of claim 1 , further comprising:

a sensor 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.

9. A display device comprising: a first substrate; a cover member opposing the first substrate; a wiring substrate connected to the first substrate; and a conductive layer maintained at a predetermined potential, the first substrate comprising an extension portion which connects the wiring substrate thereto, the cover member comprising a first surface directly overlapping the extension portion in plan view and opposing the extension portion, the conductive layer overlaps the extension portion in plan view, and the conductive layer contacting an adhesive layer between the cover member and the first substrate, a driver provided in the extension portion, wherein the conductive layer overlaps the driver at least partially in plan view.

10. The device of claim 9 , wherein the conductive layer overlaps the driver entirely in plan view.

11. The device of claim 9 , further comprising: an insulating layer located between the driver and the conductive layer.

12. The device of claim 9 , wherein

the conductive layer comprises a first end portion in contact with the first surface and a second end portion on an opposite side to the first end portion, and

the first substrate is located between the first end portion and the second end portion.

13. The device of claim 9 , wherein

the conductive layer covers the wiring substrate.

14. The device of claim 12 , wherein

the wiring substrate further comprises a reference potential member, and

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