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 (32)

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 an opening pattern at least in a partial area of the wiring, and

the opening pattern includes a first opening group having a plurality of openings arranged in a first direction in which the wiring extends.

2. The display device according to claim 1 , wherein

the opening pattern includes a second opening group having a plurality of openings arranged in the first direction, and

the second opening group is adjacent in a second direction crossing the first direction.

3. The display device according to claim 2 , wherein

at least two pairs of the first opening group and the second opening group are arranged in a second direction.

4. The display device according to claim 1 , wherein

the first opening group includes a first opening,

the second opening group includes a second opening,

the first opening and the second opening are arranged adjacent to each other in the second direction in plan view,

the first conductive layer has a lattice pattern in which the first opening and the second opening are arranged in at least a partial area of the wiring.

5. The display device according to claim 1 , wherein

a first opening included in the first opening group and a second opening included in the second opening group adjacent to the nearest distance to the first opening are located at the different position within a range of a length of the first opening in the first direction of the wiring extends in plan view.

6. The display device according to claim 1 , wherein

the wiring further includes a second conductive layer located below the first conductive layer, and

the second conductive layer is formed of a conductive metal material.

7. The display device according to claim 6 , wherein

the second conductive layer overlaps the plurality openings included in the first opening group of the first conductive layer.

8. The display device according to claim 6 , wherein

the first conductive layer includes a transparent conductive layer.

9. The display device according to claim 8 , wherein

the transparent conductive layer contains a conductive oxide.

10. The display device according to claim 9 , wherein

the conductive oxide comprises an amorphous material.

11. The display device according to claim 1 , wherein

the flexible substrate has a folding area, and

the first opening group is arranged in the folding area.
