## 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

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 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.

### Claim 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.

### Claim 8 (depends on 7)

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

### Claim 9 (depends on 8)

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.
