Abstract

A display device includes a plurality of pixel electrodes including a first pixel electrode, a first electrode adjacent to the first pixel electrode and arranged separated from the first pixel electrode, a bank covering an edge part of the first pixel electrode, an end part of the first electrode, and a region between the first pixel electrode and the first electrode, a first organic layer arranged above the first pixel electrode, above the first electrode and above the bank, a second organic layer arranged above the first organic layer overlapping the first pixel electrode, a third organic layer arranged above the second organic layer, above the first organic layer overlapping the first electrode, and above the first organic layer overlapping the bank, an opposing electrode arranged above the third organic layer overlapping the first pixel electrode, and a second electrode arranged above the third organic layer overlapping the first electrode.

Claims (31)

1. A display device comprising:

a plurality of pixel electrodes including a first pixel electrode;

a first electrode adjacent to the first pixel electrode and arranged separated from the first pixel electrode;

a bank covering an edge part of the first pixel electrode, an end part of the first electrode, and a region between the first pixel electrode and the first electrode;

a first organic layer arranged above the first pixel electrode, above the first electrode and above the bank;

a second organic layer arranged above the first organic layer overlapping the first pixel electrode;

a third organic layer arranged above the second organic layer, above the first organic layer overlapping the first electrode, and above the first organic layer overlapping the bank;

an opposing electrode arranged above the third organic layer overlapping the first pixel electrode; and

a second electrode arranged above the third organic layer overlapping the first electrode, wherein

a region stacked with the first pixel electrode, the first organic layer, the second organic layer, the third organic layer and the opposing electrode corresponds to a region of a light emitting element, and

a region stacked with the first electrode, the first organic layer, the third organic layer and the second electrode corresponds to a region of a light receiving element.

2. The display device according to claim 1 , wherein the opposing electrode is extended across the plurality of pixels continuously.

3. The display device according to claim 1 , wherein the opposing electrode and the second electrode are electrically connected.

4. The display device according to claim 1 , wherein the first organic layer includes metal phthalocyanine or acene.

5. The display device according to claim 1 , wherein the first organic layer is arranged continuously above the pixel electrode, above the first electrode and above the bank, and the third organic layer is arranged continuously above the second organic layer, above the first organic layer overlapping the first electrode, and above the first organic layer overlapping the bank.

6. A display device comprising:

a plurality of pixel electrodes including a first pixel electrode;

a bank covering an edge part of the first pixel electrode, and a region between adjacent pixel electrodes;

a first electrode arranged separated from the first pixel electrode and above the bank;

a first organic layer arranged above the first pixel electrode, above the first electrode and above the bank;

a second organic layer arranged above the first organic layer overlapping the first pixel electrode;

a third organic layer arranged above the second organic layer, above the first organic layer overlapping the first electrode, and above the first organic layer overlapping the bank;

an opposing electrode arranged above the third organic layer overlapping the first pixel electrode; and

a second electrode arranged above the third organic layer overlapping the first electrode, wherein

a region stacked with the first pixel electrode, the first organic layer, the second organic layer, the third organic layer and the opposing electrode corresponds to a region of a light emitting element, and

a region stacked with the first electrode, the first organic layer, the third organic layer and the second electrode corresponds to a region of a light receiving element.

7. The display device according to claim 6 , wherein the opposing electrode is extended across the plurality of pixels continuously.

8. The display device according to claim 6 , wherein the opposing electrode and the second electrode are electrically connected.

9. The display device according to claim 6 , wherein the pixel electrode includes a region overlapping the first electrode via the bank in a planar view.

10. The display device according to claim 6 , wherein the first organic layer includes metal phthalocyanine or acene.

11. The display device according to claim 6 , wherein the first organic layer is arranged continuously above the first pixel electrode, above the first electrode and above the bank, and the third organic layer is arranged continuously above the second organic layer, above the first organic layer overlapping the first electrode, and above the first organic layer overlapping the bank.
