## Abstract

A method for producing a display device includes locating a substrate, including a plurality of pixels, on a jig including a magnet; locating a plate formed of a magnetic material on the substrate to secure the substrate; and folding back an end portion of the substrate in a state where the substrate is held between the jig and the plate.

## Claims

### Claim 1

A display device, comprising:
a substrate including a first portion folded back with a first surface of the substrate being an inner surface and a second portion as a display region on a second surface opposite to the first surface of the substrate;
a plurality of pixels provided in the second portion;
a first marker and a second marker provided on the substrate so as to be aligned with each other as seen in a plan view;
a spacer at a position along which the substrate is folded with the first surface being an inner surface;
a third marker provided on the substrate; and
a fourth marker provided on the spacer, wherein
the spacer is located at a position overlapping the third marker in a plan view,
the third marker and the fourth marker are aligned with each other in a plan view, and
the third marker and the fourth marker are arranged in the first portion in a plan view.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein the first marker and the second marker are provided in a region other than a region where the plurality of pixels are provided.

### Claim 3 (depends on 1)

The display device according to claim 1, wherein at least one of the first marker and the second marker includes a metal layer provided on the second surface.

### Claim 4 (depends on 1)

The display device according to claim 1, further comprising an adhesive layer provided between the third marker and the fourth marker provided on the spacer.

### Claim 5 (depends on 1)

The display device according to claim 1, further comprising an IC driver connected to the first portion;
a fifth marker provided on the substrate; and
a sixth marker provided on the spacer, wherein
the fifth marker and the sixth marker are aligned with each other in a plan view.

### Claim 6 (depends on 5)

The display device according to claim 5, further comprising a seventh marker provided on the substrate; and
an eighth marker provided on the substrate, wherein
the seventh marker and the eighth marker are provided on the substrate so as to be aligned with each other in a plan view,
the first marker, the IC driver, and the seventh marker are arranged in this order, and,
the second marker, the IC driver, and the eighth marker are arranged in this order.

### Claim 7 (depends on 5)

The display device according to claim 5, wherein the fifth marker, the IC driver, and the third marker are arranged in this order, and,
the sixth marker, the IC driver, and the fourth marker are arranged in this order.
