Abstract

An organic electroluminescence display device is provided. The organic electroluminescence display device includes plural organic electroluminescence elements. Each organic electroluminescence element includes: a lower electrode; an insulating layer having an opening, in which a lower electrode is exposed at the bottom of the opening; an auxiliary wiring; a stacked structure provided from a portion over the lower electrode exposed at the bottom of the opening to a portion of the insulating layer surrounding the opening, including a light emitting layer made of an organic light-emitting material; and an upper electrode. At least one layer of the stacked structure partially contacts the auxiliary wiring. The insulating layer and the auxiliary wiring are provided in common to the plurality of organic EL elements. The upper electrode covers the whole surface of the stacked structures and the auxiliary wiring.

Claims (30)

1. An organic electroluminescence display device comprising:

an insulating layer having an opening;

a wiring;

a stacked structure formed in the opening and over a portion of the insulating layer surrounding the opening, the stacked structure including a light emitting layer made of an organic light-emitting material; and

an upper electrode covering the stacked structure and a portion of the wiring,

wherein a part of the stacked structure covers an edge of the insulating layer, and

wherein a part of the upper electrode covers an edge of the stacked structure.

2. The organic electroluminescence display device according to claim 1 , wherein a part of the upper electrode covers an edge of the stacked structure on the wiring.

3. The organic electroluminescence display device according to claim 1 , wherein a part of the upper electrode covers an edge of the stacked structure to connect to the wiring.

4. The organic electroluminescence display device according to claim 1 , wherein at least one layer of the stacked structure has a portion connected to the wiring.

5. The organic electroluminescence display device according to claim 1 , wherein the wiring is an auxiliary wiring of the upper electrode.

6. The organic electroluminescence display device according to claim 1 , further comprising a lower electrode,

wherein the organic light-emitting material dispose between the lower electrode and the upper electrode.

7. The organic electroluminescence display device according to claim 6 , wherein the organic light-emitting material is configured to emit light according to a current flowing via the lower electrode, the organic light-emitting material, the upper electrode, and the wiring.

8. The organic electroluminescence display device according to claim 1 , wherein the wiring has a belt-shape or a lattice-shape.

9. A light-emitting device comprising:

an insulating layer having an opening;

a wiring;

a stacked structure formed in the opening and over a portion of the insulating layer surrounding the opening, the stacked structure including a light emitting layer made of an organic light-emitting material; and

an upper electrode covering the stacked structure and a portion of the wiring,

wherein a part of the stacked structure covers an edge of the insulating layer, and

wherein a part of the upper electrode covers an edge of the stacked structure.

10. A light-emitting device according to claim 9 , wherein a part of the upper electrode covers an edge of the stacked structure on the wiring.

11. A light-emitting device according to claim 9 , wherein a part of the upper electrode covers an edge of the stacked structure to connect to the wiring.

12. A light-emitting device according to claim 9 , wherein at least one layer of the stacked structure has a portion connected to the wiring.

13. A light-emitting device according to claim 9 , wherein the wiring is an auxiliary wiring of the upper electrode.

14. A light-emitting device according to claim 9 , further comprising a lower electrode,

wherein the organic light-emitting material dispose between the lower electrode and the upper electrode.

15. A light-emitting device according to claim 14 , wherein the organic light-emitting material is configured to emit light according to a current flowing via the lower electrode, the organic light-emitting material, the upper electrode, and the wiring.

16. A light-emitting device according to claim 9 , wherein the wiring has a belt-shape or a lattice-shape.
