Abstract

There are provided a display unit and an electronic apparatus that are capable of preventing color mixture in adjacent color pixels, and improving color reproducibility and chromaticity viewing angle. The display unit includes: a drive substrate having a plurality of pixels with a partition therebetween; and a first light shielding film provided on the partition.

Claims (38)

1. A display device comprising:

a first substrate including a plurality of pixels including a first pixel and a second pixel with a partition therebetween, respective ones of the plurality of pixels including a light emitting layer and including an organic layer that is at least partially provided as a layer common to the plurality of pixels; and

a first light shielding film provided on the partition,

wherein the first light shielding film includes a conductive material.

2. The display device according to claim 1 , wherein the first light shielding film is set to a predetermined potential.

3. The display device according to claim 2 , further comprising a cathode, wherein the cathode is set to the predetermined potential.

4. The display device according to claim 1 , wherein the first light shielding film is provided on a top surface of the partition.

5. The display device according to claim 1 , wherein the first light shielding film is provided on a side surface of the partition.

6. The display device according to claim 1 , further comprising:

a second substrate disposed to face the first substrate; and

a black matrix provided on the second substrate and including an opening at a position corresponding to at least one of the first pixel and the second pixel,

wherein, when viewed from above, an end surface of the first light shielding film is located within the opening.

7. The display device according to claim 1 , further comprising:

a second substrate disposed to face the first substrate; and

a color filter provided on the second substrate,

wherein the color filter faces a light emitting area of the plurality of pixels.

8. The display device according to claim 1 , wherein the first light shielding film includes aluminum, chromium, gold, platinum, nickel, copper, tungsten, silver, or a combination thereof.

9. The display device according to claim 1 , wherein light emitted from the first pixel has a color different than light emitted from the second pixel.

10. The display device according to claim 1 , wherein light emitted from the first pixel and the second pixel is white light.

11. An electronic apparatus provided with a display device, the display device comprising:

a drive circuit including a plurality of pixels including a first pixel and a second pixel with a partition therebetween, respective ones of the plurality of pixels including a light emitting layer and including an organic layer that is at least partially provided as a layer common to the plurality of pixels; and

a first light shielding film provided on the partition,

wherein the first light shielding film includes a conductive material.

12. The electronic apparatus according to claim 11 , wherein the first light shielding film is set to a predetermined potential.

13. The electronic apparatus according to claim 12 , further comprising a cathode, wherein the cathode is set to the predetermined potential.

14. The electronic apparatus according to claim 11 , wherein the first light shielding film is provided on a top surface of the partition.

15. The electronic apparatus according to claim 11 , wherein the first light shielding film is provided on a side surface of the partition.

16. The electronic apparatus according to claim 11 , further comprising:

a counter substrate disposed to face the drive circuit; and

a black matrix provided on the counter substrate and including an opening at a position corresponding to at least one of the first pixel and the second pixel,

wherein, when viewed from above, an end surface of the first light shielding film is located within the opening.

17. The electronic apparatus according to claim 11 , further comprising:

a counter substrate disposed to face the drive circuit; and

a color filter provided on the counter substrate,

wherein the color filter faces a light emitting area of the plurality of pixels.

18. The electronic apparatus according to claim 11 , wherein the first light shielding film includes aluminum, chromium, gold, platinum, nickel, copper, tungsten, silver, or a combination thereof.

19. The electronic apparatus according to claim 11 , wherein light emitted from the first pixel has a color different than light emitted from the second pixel.

20. The electronic apparatus according to claim 11 , wherein light emitted from the first pixel and the second pixel is white light.
