Abstract

Provided is a display device including a display panel and an input sensing unit. The input sensing unit includes at least one insulation layer, an electrode, and an auxiliary electrode. The electrode includes sensor parts including a metal and having a mesh shape and connection parts connecting adjacent sensor parts of the sensor parts to each other. The auxiliary electrode overlaps the sensor parts, is connected to the sensor parts, and includes transparent conductive oxide.

Claims (23)

1. A display device comprising:

a display panel comprising:

a base surface including a plurality of emission areas and a non-emission area adjacent to the plurality of emission areas; and

an input sensing unit disposed on the display panel,

wherein the input sensing unit comprises:

a noise shield electrode directly disposed on the base surface and having transparent conductive oxide;

a first electrode disposed on the noise shield electrode, the first electrode having a mesh shape and a plurality of holes corresponding to the plurality of emission areas; and

a second electrode disposed on the noise shield electrode and the first electrode, the second electrode crossing the first electrode,

wherein the first electrode and the second electrode overlap the noise shield electrode in a plan view, and

wherein the second electrode comprises a transparent conductive oxide and overlaps the plurality of emission areas and the non-emission area.

2. The display device of claim 1 , wherein the second electrode is provided in plurality, and

the plurality of second electrodes are disposed inside the noise shield electrode in a plan view.

3. The display device of claim 1 , wherein the noise shield electrode overlaps the plurality of emission areas and the non-emission area.

4. The display device of claim 3 , wherein the input sensing unit further comprises a first insulation layer disposed between the noise shield electrode and the first electrode and a second insulation layer disposed between the first electrode and the second electrode to cover the first electrode.

5. The display device of claim 4 , further comprising an optical transparent adhesion member between the second insulation layer and the second electrode.

6. The display device of claim 1 , further comprising a first insulation layer directly disposed on the noise shield electrode,

wherein the first electrode is directly disposed on the first insulation layer.

7. The display device of claim 6 , further comprising an optical transparent adhesion member between the first insulation layer and the second electrode.

8. The display device of claim 1 , wherein the first electrode is disposed between the noise shield electrode and the second electrode.

9. The display device of claim 8 , further comprising an antireflection unit disposed between the first electrode and the second electrode.

10. The display device of claim 9 , wherein the antireflection unit comprises a polarization film, and

the display device further comprises an optical transparent adhesion member disposed between the polarization film and the first electrode.

11. The display device of claim 9 , wherein the second electrode is directly disposed on the antireflection unit.
