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 (40)

1. A display unit comprising:

a drive substrate having a plurality of pixels with a partition therebetween, wherein each of the pixels includes a light emitting layer, and has 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 is provided between the partition and the organic layer.

2. The display unit according to claim 1 , wherein light emitted from the light emitting layer is white light.

3. The display unit according to claim 1 , wherein

the partition has a flat top surface and an inclined side surface, and

the first light shielding film is provided on the flat top surface of the partition.

4. The display unit according to claim 1 , wherein

the partition has a flat top surface and an inclined side surface, and

the first light shielding film is provided on the flat top surface and the inclined side surface.

5. The display unit according to claim 1 , further comprising

a black matrix provided on a counter substrate side and having an opening at a position corresponding to the pixel, the counter substrate being disposed to face the drive substrate, wherein

the first light shielding film has an end surface on a pixel side rather than an end surface of the opening of the black matrix as viewed from a display surface.

6. The display unit according to claim 5 , further comprising

a second light shielding film between the first light shielding film and the black matrix.

7. The display unit according to claim 1 , wherein the first light shielding film has light absorbing property.

8. The display unit according to claim 7 , wherein the first light shielding film is formed of carbon (C), chromium oxide (Cr 2 O 3 ), and an alloy of samarium (Sm) and silver (Ag), or an organic material.

9. The display unit according to claim 1 , wherein the first light shielding film has light reflectivity.

10. The display unit according to claim 9 , wherein the first light shielding film contains one or more of aluminum (Al), chromium (Cr), gold (Au), platinum (Pt), nickel (Ni), copper (Cu), tungsten (W), and silver (Ag).

11. The display unit according to claim 1 , wherein light emitted from the light emitting layer is different by pixels.

12. An electronic apparatus provided with a display unit, the display unit comprising:

a drive circuit having a plurality of pixels with a partition therebetween, wherein each of the pixels includes a light emitting layer, and has 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 is provided between the partition and the organic layer.

13. The electronic apparatus according to claim 12 , wherein the first light shielding film contains one or more of aluminum (Al), chromium (Cr), gold (Au), platinum (Pt), nickel (Ni), copper (Cu), tungsten (W), and silver (Ag).

14. The electronic apparatus according to claim 12 , wherein

the partition has a flat top surface and an inclined side surface, and

the first light shielding film is provided on the flat top surface of the partition.

15. The electronic apparatus according to claim 12 , wherein

the partition has a flat top surface and an inclined side surface, and

the first light shielding film is provided on the flat top surface and the inclined side surface.

16. The electronic apparatus according to claim 12 , further comprising

a black matrix provided on a counter substrate side and having an opening at a position corresponding to the pixel, the counter substrate being disposed to face the drive substrate, wherein

the first light shielding film has an end surface on a pixel side rather than an end surface of the opening of the black matrix as viewed from a display surface.

17. The electronic apparatus according to claim 16 , further comprising

a second light shielding film between the first light shielding film and the black matrix.

18. The electronic apparatus according to claim 12 , wherein the first light shielding film is formed of carbon (C), chromium oxide (Cr 2 O 3 ), and an alloy of samarium (Sm) and silver (Ag), or an organic material.

19. A display unit comprising:

a drive substrate having a plurality of pixels with a partition therebetween, the partition having a top surface; and

a light shielding film provided on and in contact with the top surface of the partition.

20. An electronic apparatus including the display unit according to claim 19 .
