Abstract

There is included a pixel including a plurality of sub-pixels, each of the sub-pixels including a single first electrode, a single second electrode provided along a laminating direction of the first electrode, and a light-emitting layer inserted between the first electrode and the second electrode. One or more of the plurality of sub-pixels have a plurality of light emission regions including two or more light emission regions different in one or more of shape, size, and orientation from one another.

First claim

1 . A display unit comprising:
a pixel including a plurality of sub-pixels, each of the sub-pixels including a single first electrode, a single second electrode provided along a laminating direction of the first electrode, and a light-emitting layer inserted between the first electrode and the second electrode, wherein one or more of the plurality of sub-pixels have a plurality of light emission regions including two or more light emission regions different in one or more of shape, size, and orientation from one another.

2 . The display unit according to claim 1 , wherein
the sub-pixel including the plurality of light emission regions includes a first insulating layer formed on the first electrode and including opening sections in positions corresponding to the respective light emission regions, and a second insulating layer with a different refractive index from a refractive index of the first insulating layer, the second insulating layer formed on the second electrode, and the first electrode, the light-emitting layer, the second electrode, the second insulating layer are laminated in order on a bottom of the opening section.

3 . The display unit according to claim 1 , wherein each of the plurality of sub-pixels includes the plurality of light emission regions.

4 . The display unit according to claim 3 , wherein the plurality of light emission regions are provided in a same arrangement pattern in the plurality of sub-pixels.

5 . The display unit according to claim 3 , wherein the plurality of light emission regions are provided in an arrangement pattern that is different between the plurality of sub-pixels.

6 . The display unit according to claim 4 , comprising a plurality of pixels each being the pixel, wherein
the arrangement patterns of the mutually-corresponding sub-pixels in the adjacent pixels are the same as each other.

7 . The display unit according to claim 4 , comprising a plurality of pixels each being the pixel, wherein
the arrangement patterns of the mutually-corresponding sub-pixels in the adjacent pixels are different from each other.

8 . The display unit according to claim 3 , wherein the plurality of sub-pixels include a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel, the first to third sub-pixels each configured to emit basic color light, and the fourth sub-pixel configured to emit non-basic color light.

9 . The display unit according to claim 8 , wherein the light emission regions in the fourth sub-pixel are smaller in number than those in the other sub-pixels.

10 . The display unit according to claim 3 , wherein the plurality of sub-pixels include a first sub-pixel, a second sub-pixel, and a third sub-pixel each of which is configured to emit basic color light.

11 . The display unit according to claim 1 , wherein
the plurality of sub-pixels include a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel, the first to third sub-pixels each configured to emit basic color light, and the fourth sub-pixel configured to emit non-basic color light, each of the first sub-pixel, the second sub-pixel, and the third sub-pixel includes a plurality of light emission regions, and the fourth sub-pixel includes a single light emission region.

12 . The display unit according to claim 1 , wherein light emission regions adjacent to each other of the plurality of light emission regions are different in one or more of shape, size, and orientation from each other.

13 . The display unit according to claim 1 , wherein the plurality of light emission regions are provided in an arrangement pattern based on a Voronoi diagram.

14 . The display unit according to claim 1 , wherein the plurality of light emission regions are provided in an orderly arrangement pattern without periodicity.

15 . The display unit according to claim 14 , wherein the arrangement pattern is based on a Penrose tiling.

16 . The display unit according to claim 14 , wherein the arrangement pattern is based on a Fibonacci spiral.

17 . The display unit according to claim 14 , wherein the arrangement pattern is based on a pattern in which pentagons are spread without gap.

18 . The display unit according to claim 14 , wherein the arrangement pattern is based on an atomic arrangement of a paracrystal.

19 . The display unit according to claim 1 , wherein each of shapes of the plurality of light emission regions is a circular shape or an ellipsoidal shape.

20 . The display unit according to claim 19 , wherein three light emission regions of the plurality of light emission regions are provided adjacent to one another.

21 . An electronic apparatus provided with a display unit and a control section configured to perform operation control on the display unit, the display unit comprising:
a pixel including a plurality of sub-pixels, each of the sub-pixels including a single first electrode, a single second electrode provided along a laminating direction of the first electrode, and a light-emitting layer inserted between the first electrode and the second electrode, wherein one or more of the plurality of sub-pixels have a plurality of light emission regions including two or more light emission regions different in one or more of shape, size, and orientation from one another.
