Abstract

Provided is a display device, including: a plurality of pixels that are provided between a first substrate and a light-transparent second substrate, the plurality of pixels each including a light-reflective first electrode, an organic layer, and a light-transparent second electrode in order from the first substrate side, the organic layer including at least a light-emission layer; a first light-shielding layer that is provided in a region between the plurality of pixels on one side of the second substrate; and a second light-shielding layer that is provided between the first light-shielding layer and the first substrate, the second light-shielding layer facing at least part of the first light-shielding layer.

Claims (26)

1. A display device, comprising:

a plurality of pixels that are provided between a first substrate and a light-transparent second substrate, the plurality of pixels each including a light-reflective first electrode, an organic layer, and a light-transparent second electrode in order from the first substrate side, the organic layer including at least a light-emission layer;

a first light-shielding layer that is provided in a region between the plurality of pixels on one side of the second substrate; and

a second light-shielding layer that is provided between the first light-shielding layer and the first substrate, the second light-shielding layer facing at least part of the first light-shielding layer.

2. The display device according to claim 1 , wherein the second light-shielding layer is formed on the second electrode in a lattice shape.

3. The display device according to claim 1 , wherein the second light-shielding layer is formed on the second electrode in a stripe shape.

4. The display device according to claim 1 ,

wherein the plurality of pixels include three or more kinds of pixels that are configured to emit lights of different wavelengths from one another, and

the second light-shielding layer is formed in a region between the pixels that are configured to emit lights of relatively close wavelengths among the three or more kinds of pixels.

5. The display device according to claim 1 ,

wherein the plurality of pixels include a white pixel that is configured to emit white light, and

the second light-shielding layer is formed to surround the white pixel.

6. The display device according to claim 1 , further comprising a color filter layer, the color filter layer being configured to selectively allow light of specific wavelength to pass through,

wherein the first light-shielding layer includes a plurality of apertures, and

the color filter layer is provided inside the plurality of apertures.

7. The display device according to claim 1 , further comprising a high-resistivity layer that is provided between the organic layer and the second electrode.

8. The display device according to claim 7 , wherein the second light-shielding layer is provided on the second electrode.

9. The display device according to claim 7 , wherein the second light-shielding layer is provided between the high-resistivity layer and the second electrode.

10. The display device according to claim 1 , wherein the second light-shielding layer includes a conductive material.

11. The display device according to claim 1 , wherein the second light-shielding layer is formed by printing.

12. The display device according to claim 11 , further comprising an inter-pixel insulating film that is provided with a hole to face the first electrode,

wherein the second light-shielding layer is formed by offset printing utilizing unevenness of a surface of the inter-pixel insulating film.

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

a plurality of pixels that are provided between a first substrate and a light-transparent second substrate, the plurality of pixels each including a light-reflective first electrode, an organic layer, and a light-transparent second electrode in order from the first substrate side, the organic layer including at least a light-emission layer;

a first light-shielding layer that is provided in a region between the plurality of pixels on one side of the second substrate; and

a second light-shielding layer that is provided between the first light-shielding layer and the first substrate, the second light-shielding layer facing at least part of the first light-shielding layer.
