Abstract

A display device that includes a plurality of light-emitting elements, a first light-absorbing layer having an opening at a position that faces the light-emitting elements, and a second light-absorbing layer that faces the first light-absorbing layer with the light-emitting elements therebetween.

Claims (27)

1. A display device comprising:

a substrate;

a plurality of light-emitting elements;

a first light-absorbing layer having an opening at a position that faces the plurality of light-emitting elements; and

a second light-absorbing layer that faces the first light-absorbing layer with the plurality of light-emitting elements therebetween;

a wiring line layer between the substrate and the second light-absorbing layer; and

an insulating layer between the wiring line layer and the second light-absorbing layer.

2. The display device according to claim 1 , wherein the second light-absorbing layer is disposed in a region including a region that faces the opening of the first light-absorbing layer.

3. The display device according to claim 1 , further comprising a third light-absorbing layer provided between the substrate and the wiring line layer.

4. The display device according to claim 1 , wherein the second light-absorbing layer includes a resin material or a metal material.

5. The display device according to claim 1 , wherein the plurality of light-emitting elements include an inorganic semiconductor material.

6. A display device, comprising:

a substrate;

a plurality of light-emitting elements;

a first light-absorbing layer having an opening at a position that faces the plurality of light-emitting elements;

a second light-absorbing layer that faces the first light-absorbing layer with the plurality of light-emitting elements therebetween;

a wiring line layer between the substrate and the second light-absorbing layer, wherein the second light-absorbing layer is in contact with the wiring line layer; and

an Under Bump Metal (UBM) between the second light-absorbing layer and the plurality of light-emitting elements.

7. A display device, comprising:

a substrate;

a plurality of light-emitting elements;

a first light-absorbing layer having an opening at a position that faces the plurality of light-emitting elements;

a second light-absorbing layer that faces the first light-absorbing layer with the plurality of light-emitting elements therebetween;

a wiring line layer between the substrate and the second light-absorbing layer; and

a third light-absorbing layer between the substrate and the wiring line layer.

8. The display device according to claim 7 , wherein the second light-absorbing layer is separated by a gap.

9. The display device according to claim 8 , wherein the plurality of light-emitting elements are at a position that faces at least a portion of the gap.
