Abstract

A multi-display includes a first display device and a second display device. The first display device includes a first substrate including a first display surface and a first side surface continuous with the first display surface, a first display portion on the first display surface, and a first side wiring extending from the first side surface to the first display surface. The second display device includes a second substrate including a second display surface and a second side surface continuous with the second display surface, a second display portion on the second display surface, and a second side wiring extending from the second side surface to the second display surface. The first side surface and the second side surface are adjacent to and face each other. The first side wiring and the second side wiring are located without facing each other.

First claim

wherein the first side surface and the second side surface are adjacent to and face each other, and
the first side wiring and the second side wiring are located without facing each other.

2. The multi-display according to claim 1 , wherein
the first side wiring is out of contact with the second side surface, and
the second side wiring is out of contact with the first side surface.

3. The multi-display according to claim 1 , further comprising:
a first protective layer covering the first side wiring; and
a second protective layer covering the second side wiring.

4. The multi-display according to claim 3 , wherein
the first protective layer is out of contact with the second side surface, and
the second protective layer is out of contact with the first side surface.

5. The multi-display according to claim 3 , wherein
the first protective layer covers the first side surface, and
the second protective layer covers the second side surface.

6. The multi-display according to claim 1 , wherein

the second side wiring is at least partially located between pixels adjacent to the second side surface as viewed in plan, and the pixels adjacent to the second side surface are pixels of a plurality of outermost pixels in outermost rows and columns of the matrix.

11. The multi-display according to claim 1 , wherein
the first display device includes first wiring located at an edge of the first display surface adjacent to the first side surface and connected to at least one of a plurality of pixels in the first display portion, the first wiring includes a first end face adjacent to the first side surface located inward from the first side surface, and the first end face is covered with the first side wiring or covered with the first side wiring and a first protective layer covering the first side wiring, and
the second display device includes second wiring located at an edge of the second display surface adjacent to the second side surface and connected to at least one of a plurality of pixels in the second display portion, the second wiring includes a second end face adjacent to the second side surface located inward from the second side surface, and the second end face is covered with the second side wiring or covered with the second side wiring and a second protective layer covering the second side wiring.

12. The multi-display according to claim 1 , wherein
the first display device includes a first drive on a first non-display surface opposite to the first display surface, and the second display device includes a second drive on a second non-display surface opposite to the second display surface,
in the first display device, the first drive is electrically connected to at least one of a plurality of pixels in the first display portion with the first side wiring, and
in the second display device, the second drive is electrically connected to at least one of a plurality of pixels in the second display portion with the second side wiring.

13. The multi-display according to claim 1 , wherein
the first side wiring and the second side wiring are electrically connectable to each other.

14. The multi-display according to claim 1 , wherein
the first display portion includes at least one light emitter and the second display portion includes at least one light emitter.

15. A display device, comprising:
a substrate including a display surface, a side surface continuous with the display surface, and an opposite side surface opposite to the side surface;
a display portion on the display surface;
a side wiring extending from the side surface to the display surface; and
an opposite side wiring extending from the opposite side surface to the display surface,
wherein the side wiring and the opposite side wiring are located without facing each other.

16. The display device according to claim 15 , wherein
