Abstract

Provided is a highly reliable display device that does not easily cause a wiring or an interlayer insulating layer to be cracked when being folded. A display device includes a flexible substrate; a plurality of pixels arrayed on the substrate; and a wiring, provided on the substrate, transmitting a signal to drive the plurality of pixels. The wiring includes a first conductive layer having an opening pattern at least in a partial area thereof.

Claims (33)

1. A display device, comprising:

a flexible substrate;

a plurality of pixels arrayed on the substrate; and

a wiring, provided on the substrate, transmitting a signal that drives the plurality of pixels;

wherein the wiring includes a first conductive layer having plurality of first openings at least in a partial area of the wiring, and

the plurality of first openings are arranged in a longitudinal direction of the wiring.

2. The display device according to claim 1 , wherein the first conductive layer includes a transparent conductive layer.

3. The display device according to claim 2 , wherein the transparent conductive layer contains a conductive oxide.

4. The display device according to claim 3 , wherein the conductive oxide is amorphous.

5. The display device according to claim 1 , wherein the first conductive layer has a plurality of second openings arranged in a first direction that intersects the longitudinal direction.

6. The display device according to claim 5 , wherein the first conductive layer has a lattice pattern formed by the first openings and the second openings.

7. The display device according to claim 5 , wherein the second openings include a third opening, a fourth opening, and a fifth opening adjacent to one another, the fifth opening located between the third and fourth openings,

the third opening has a first edge portion in the longitudinal direction,

the fourth opening has a second edge portion in the longitudinal direction,

the fifth opening has a third edge portion in the longitudinal direction,

the first and second edge portions are arranged in a second direction, and

the first and fifth edge portions are not arranged in the second direction.

8. The display device according to claim 1 , wherein the partial area is a folding area.

9. The display device according to claim 1 , wherein each of the first openings have a striped pattern.

10. The display device according to claim 1 , wherein the wiring further includes a second conductive layer located below the first conductive layer,

the second conductive layer is formed of a conductive metal material, and overlaps the plurality of first openings of the first conductive layer.

11. A display device, comprising:

a flexible substrate; and

a plurality of pixels arrayed in a matrix on the substrate;

wherein:

each of the plurality of pixels includes a light-emitting element having a stack structure including a pixel electrode, a light-emitting layer, and a common electrode; and

the pixel electrode includes a first conductive layer having a plurality of first openings, a second conductive layer above the first conductive layer, and a third conductive layer above the second conductive layer,

the second conductive layer is formed of a light-reflective material, and overlaps the plurality of first openings of the first conductive layer.

12. The display device according to claim 11 , wherein the first conductive layer includes a transparent conductive layer.

13. The display device according to claim 12 , wherein the transparent conductive layer contains a conductive oxide.

14. The display device according to claim 13 , wherein the conductive oxide is amorphous.

15. The display device according to claim 11 , wherein the plurality of first openings include a plurality of second openings arranged in a first direction, and a plurality of third openings arranged in a second direction intersecting the first direction.

16. The display device according to claim 15 , wherein the first conductive layer has a lattice pattern formed by the second and the third openings.
