Abstract
A display device includes a flexible substrate, a display portion provided on a first surface of the flexible substrate and including a plurality of pixels, a first penetrating wiring located to penetrate the flexible substrate, and a second penetrating wiring located to penetrate the flexible substrate at a position farther from the display portion than the first penetrating wiring. The flexible substrate includes a curved portion between the first penetrating wiring and the second penetrating wiring. The first penetrating wiring and the second penetrating wiring are electrically connected with each other without being extended on the curved portion.

A display device, comprising:
- a flexible substrate;
- a display portion provided on a first surface of the flexible substrate and including a plurality of pixels;
- a first penetrating wiring located to penetrate the flexible substrate;
- a second penetrating wiring located to penetrate the flexible substrate at a position farther from the display portion than the first penetrating wiring;
- and a spacer,
- wherein:
- the flexible substrate includes a curved portion between the first penetrating wiring and the second penetrating wiring,
- the first penetrating wiring and the second penetrating wiring are electrically connected with each other without being extended on the curved portion,
- the flexible substrate includes a first region including the first penetrating wiring, a second region including the second penetrating wiring, and a third region including the curved portion,
- the spacer is located between the first region and the second region, and
- the first penetrating wiring and the second penetrating wiring are electrically connected with each other via a third penetrating wiring located to penetrate the spacer.
A method for manufacturing a display device, comprising:
- forming a resin layer on a support substrate;
- forming a first through-hole and a second through-hole in the resin layer;
- forming a first penetrating wiring in the first through-hole and forming a second penetrating wiring in the second through-hole;
- forming a display circuit including a plurality of semiconductor elements on a first surface of the resin layer;
- and
- releasing the resin layer from the support substrate, and then curving the resin layer at a position between the first penetrating wiring and the second penetrating wiring to electrically connect the first penetrating wiring and the second penetrating wiring to each other,
- wherein:
- after the resin layer is released from the support substrate, a spacer is located on a second surface of the resin layer opposite to the first layer to electrically connect the first penetrating wiring with a third penetrating wiring located to penetrate the spacer, and
- the resin layer is curved at a position between the first penetrating wiring and the second penetrating wiring to electrically connect the second penetrating wiring and the third penetrating wiring to each other.
