Abstract

A display unit comprising an organic layer between a light-emitting section portion of a first electrode layer and a light-emitting section portion of a second electrode layer. Light is emissible from within the organic layer. An aperture-defining insulating film is between a contact section of the first electrode layer and a gap section portion of the second electrode layer. The thickness of the gap section portion of the second electrode layer is greater than the thickness of the light-emitting section portion of the second electrode layer.

Claims (36)

1. A display unit comprising:

an organic layer between a light-emitting section portion of a first electrode layer and a light-emitting section portion of a second electrode layer, light being emissible from within said organic layer;

an aperture-defining insulating film between a contact section of the first electrode layer and a gap section portion of the second electrode layer,

wherein said gap section portion of the second electrode layer comprises a first conductive layer and a second conductive layer, said second conductive layer being in physical contact with said first conductive layer,

wherein said first conductive layer and said light-emitting section portion of the second electrode layer are a same material, said first conductive layer and said second conductive layer being of different materials,

wherein the thickness of said gap section portion of the second electrode layer is greater than the thickness of said light-emitting section portion of the second electrode layer.

2. A display unit according to claim 1 , further comprising:

wiring electrically connected to said contact section of the first electrode layer, said contact section of the first electrode layer being between said aperture-defining insulating film and said wiring.

3. A display unit according to claim 2 , further comprising:

a driving transistor electrically connected to said contact section of the first electrode layer.

4. A display unit according to claim 1 , wherein said organic layer comprises:

a hole transportation layer between a hole injection layer and a luminescent layer, said luminescent layer being between an electron transportation layer and said hole transportation layer.

5. A display unit according to claim 1 , wherein a volume resistivity of the second conductive layer is lower than a volume resistivity of the first conductive layer.

6. A display unit according to claim 1 , wherein said first conductive layer is an indium tin oxide layer.

7. A display unit according to claim 1 , wherein said first conductive layer includes indium, zinc, and oxygen.

8. A display unit according to claim 1 , wherein said second conductive layer is a conductive metallic material.

9. A display unit according to claim 1 , wherein said first conductive layer is electrically connected to said light-emitting section portion of the second electrode layer.

10. A display unit according to claim 1 , wherein said light is transmissible through said first conductive layer, said second conductive layer being opaque to said light.

11. A display unit according to claim 1 , wherein an opening extends through a planarizing film, said contact section of the first electrode layer being within said opening.

12. A display unit according to claim 11 , wherein said light-emitting section portion of the first electrode layer is between said organic layer and said planarizing film.

13. A display unit according to claim 1 , wherein said first electrode layer is an optically reflective conductive material.

14. A display unit according to claim 1 , wherein said first electrode layer in aluminum or an aluminum alloy.

15. A display unit according to claim 1 , wherein said first conductive layer is an optically transparent conductive material.

16. A display unit according to claim 1 , wherein said second conductive layer is an optically opaque conductive material.

17. A display unit according to claim 1 , wherein said second conductive layer is a material from the group consisting of aluminum, copper and gold.

18. A display unit according to claim 1 , wherein said aperture-defining insulating film is in physical contact with said first conductive layer and said contact section of the first electrode layer.

19. A display unit according to claim 1 , wherein said organic layer is in physical contact with said aperture-defining insulating film and said first conductive layer.

20. A display unit according to claim 1 , wherein said first conductive layer is between said aperture-defining insulating film and said second conductive layer.

21. A display unit according to claim 1 , further comprising:

a protective film between said second electrode layer and a sealing substrate.

22. A display unit according to claim 21 , wherein said protective film is in physical contact with second electrode layer and said sealing substrate.

23. A display unit according to claim 21 , wherein said protective film is in physical contact with said second conductive layer.

24. A display unit according to claim 21 , wherein said protective film is in physical contact with said light-emitting section portion of the second electrode layer.

25. An electronic apparatus comprising:

the display unit according to claim 1 ;

a housing, said display unit being in said housing.
