wherein the display region is capable of displaying an image,
wherein the display region is not rectangular,
wherein the terminal electrode is electrically connected to the external electrode through an opening, and
wherein the opening passes through the substrate and the insulating layer.
2. The display device according to claim 1 ,
wherein the display region comprises a light-emitting element.
3. The display device according to claim 2 ,
wherein the light-emitting element is configured to emit white light.
4. The display device according to claim 2 , further comprising a color filter overlapping with the light-emitting element.
5. A display device comprising:
a first substrate;
a second substrate;
an insulating layer;
a light-emitting element;
a first electrode; and
a second electrode,
wherein the insulating layer is provided above the first substrate,
wherein the first electrode is provided above the insulating layer,
wherein the light-emitting element is provided above the first electrode,
wherein the second substrate is provided above the light-emitting element,
wherein light emitted from the light-emitting element exits through the second substrate,
wherein, in an opening passing through the first substrate and the insulating layer, the first electrode is electrically connected to the second electrode, and
wherein an external shape of the display device is not rectangular.
6. The display device according to claim 5 ,
wherein the first substrate and the second substrate each have flexibility.
7. The display device according to claim 5 ,
wherein the light-emitting element is configured to emit white light.

9. An electronic device comprising:
the display device according to claim 5 ; and
a touch sensor.
10. An electronic device comprising:
a first substrate;
a second substrate;
an insulating layer;
a light-emitting element;
a first electrode;
a second electrode; and
a touch sensor overlapping with the light-emitting element,
wherein the insulating layer is provided above the first substrate,
wherein the first electrode is provided above the insulating layer,
wherein the light-emitting element is provided above the first electrode,
wherein the second substrate is provided above the light-emitting element,
wherein light emitted from the light-emitting element exits through the second substrate, and
wherein, in an opening passing through the first substrate and the insulating layer, the first electrode is electrically connected to the second electrode.
11. The electronic device according to claim 10 ,
wherein the first substrate and the second substrate each have flexibility.
