Abstract

A display device includes a first region and a second region adjacent to the first region. A display element included in the first region has a function of reflecting visible light and a function of emitting visible light. A display element included in the second region has a function of emitting visible light. In an electronic device including the display device, the first region is located on a first surface (e.g., top surface) on which a main image is displayed, and the second region is located on a second surface (e.g., side surface) on which an auxiliary image is displayed.

Claims (44)

1. An electronic device comprising:

a first display region having a flat surface, the first display region including two long sides and two short sides;

a second display region having a curved region, the second display region extending from one of the two long sides of the first display region; and

a driver circuit which outputs a signal for driving pixels included in the first display region and the second display region to the first display region and the second display region,

wherein the second display region is between the first display region and the driver circuit, and

wherein part of the driver circuit extends beyond the one of the two long sides of the first display region.

2. The electronic device according to claim 1 , wherein the first display region and the second display region are configured to display different images.

3. The electronic device according to claim 1 ,

wherein the first display region includes a first pixel,

wherein the second display region includes a second pixel,

wherein the first pixel includes a first display element,

wherein the second pixel includes a second display element, and

wherein each of the first display element and the second display element is a light-emitting element.

4. The electronic device according to claim 1 , further comprising a housing,

wherein the first display region is over a first surface of the housing, and

wherein the second display region is over a first side surface adjacent to the first surface of the housing.

5. The electronic device according to claim 4 , wherein a third display region is over a second side surface opposite to the first side surface of the housing.

6. The electronic device according to claim 1 , wherein the driver circuit is a gate driver circuit.

7. The electronic device according to claim 1 , wherein one of the pixels includes a transistor comprising an oxide semiconductor.

8. An electronic device comprising:

a first display region having a flat surface, the first display region including two long sides and two short sides;

a second display region having a curved region, the second display region extending from one of the two long sides of the first display region;

a driver circuit which outputs a signal for driving pixels included in the first display region and the second display region to the first display region and the second display region; and

a flexible substrate,

wherein the second display region is between the first display region and the driver circuit,

wherein part of the driver circuit extends beyond the one of the two long sides of the first display region,

wherein the first display region and the second display region are over the flexible substrate, and

wherein the flexible substrate has a protruded portion which extends from one of the two short sides of the first display region and is overlapped with a flexible printed circuit.

9. The electronic device according to claim 8 , wherein the first display region and the second display region are configured to display different images.

10. The electronic device according to claim 8 , wherein the driver circuit is electrically connected to the flexible printed circuit through a wiring.

11. The electronic device according to claim 8 ,

wherein the first display region includes a first pixel,

wherein the second display region includes a second pixel,

wherein the first pixel includes a first display element,

wherein the second pixel includes a second display element, and

wherein each of the first display element and the second display element is a light-emitting element.

12. The electronic device according to claim 8 , further comprising a housing having a first surface and a first side surface,

wherein the first display region is over the first surface of the housing, and

wherein the second display region is over the first side surface of the housing adjacent to the first surface of the housing.

13. The electronic device according to claim 12 ,

wherein the housing has a second side surface opposite to the first side surface,

wherein a third display region is over the second side surface of the housing.

14. The electronic device according to claim 8 , wherein the driver circuit is a gate driver circuit.

15. The electronic device according to claim 8 , wherein one of the pixels includes a transistor comprising an oxide semiconductor.
