Abstract

[Object] To make it possible to improve viewing angle characteristics more. [Solution] Provided is a display device including: a plurality of light emitting sections formed on a substrate. The light emitting section has a configuration in which a luminescence layer is sandwiched by a first electrode functioning as a reflecting electrode and a second electrode in a stacking direction, a surface of the first electrode facing the luminescence layer is inclined from a plane perpendicular to the stacking direction in at least a partial region in a display surface, and an inclination direction of the first electrode has a distribution in the display surface.

Claims (31)

1. A display device comprising:

light emitting elements between a first substrate and a layer of color filters,

wherein, in a first region of the display device:

the layer of color filters comprises first region color filters,

a first one of the first region color filters is between a second substrate and a first one of the light emitting elements,

the first one of the first region color filters is between a second one of the first region color filters and a third one of the first region color filters, and

the second one of the first region color filters is closer to the second substrate than the first one of the first region color filters.

2. The display device according to claim 1 , wherein the first one of the first region color filters is closer to the second substrate than the third one of the first region color filters.

3. The display device according to claim 1 , wherein a first color of light is transmissible through the first one of the first region color filters, the first color of light is of a color other than a second color of light.

4. The display device according to claim 3 , wherein the second color of light is transmissible through the second one of the first region color filters, the second color of light is of a color other than a third color of light.

5. The display device according to claim 1 , wherein the third color of light is transmissible through the third one of the first region color filters, the third color of light is of a color other than the first color of light.

6. The display device according to claim 1 , wherein, in a second region of the display device:

the layer of color filters comprises second region color filters, the first one of the second region color filters is between a second one of the second region color filters and a third one of the second region color filters.

7. The display device according to claim 6 , wherein the second one of the second region color filters is closer to the second substrate than the first one of the second region color filters.

8. The display device according to claim 7 , wherein the first one of the second region color filters is closer to the second substrate than the third one of the second region color filters.

9. The display device according to claim 6 , wherein, in the second region of the display device, a first one of the second region color filters is between the second substrate and a second one of the light emitting elements.

10. The display device according to claim 9 , wherein:

the second one of the light emitting elements is configured to emit, along a direction perpendicular to a luminescence surface for the second one of the light emitting elements, a light beam that passes through the second substrate and a first one of the second region color filters.

11. The display device according to claim 10 , wherein:

the first one of the light emitting elements is configured to emit, along a direction perpendicular to a luminescence surface for the first one of the light emitting elements, a light beam that passes through the second substrate and the first one of the first region color filters.

12. The display device according to claim 11 , wherein the direction perpendicular to the luminescence surface of the first region light emitting element is a direction other than the direction perpendicular to the luminescence surface of the second region light emitting element.

13. The display device according to claim 6 , wherein a first line of display regions, as seen from a front of the display device, comprises the first region and the second the region.

14. The display device according to claim 13 , wherein a third region of the display device is between the first region and the second region, the third region is between a fourth region of the display device and a fifth region of the display device.

15. The display device according to claim 14 , wherein a second line of the display regions, as seen from a front of the display device, comprises the fourth region and the fifth region.

16. The display device according to claim 15 , wherein the first line of the display regions crosses the second line of the display regions at the third region.

17. The display device according to claim 16 , wherein the third region is at an intersection of the second line of the display regions and the first line of the display regions.

18. The display device according to claim 1 , wherein the first light emitting element comprises an organic light emitting diode.

19. The display device according to claim 18 , wherein the second light emitting element comprises another organic light emitting diode.

20. An electronic apparatus comprising:

the display device according to claim 1 ,

wherein the display device is configured to perform display on a basis of an image signal.
