Abstract

Provided is a novel display device that is highly convenient or reliable or a display device with low power consumption and high display quality. The display device includes a first pixel and a second pixel. The first pixel and the second pixel are adjacent to each other. Each of the first pixel and the second pixel includes a first display region and a second display region. The first display region is configured to reflect incident light. The second display region is positioned inside the first display region and configured to emit light. A position of the second display region inside the first display region in the first pixel and a position of the second display region inside the first display region in the second pixel are different from each other.

Claims (68)

1. A display device comprising:

a first pixel; and

a second pixel,

wherein the first pixel and the second pixel are adjacent to each other,

wherein each of the first pixel and the second pixel comprises a first display region and a second display region,

wherein the first display region is configured to reflect incident light,

wherein the second display region is positioned inside the first display region and configured to emit light, and

wherein a position of the second display region inside the first display region in the first pixel and a position of the second display region inside the first display region in the second pixel are different from each other.

2. The display device according to claim 1 ,

wherein an interval between the second display region in the first pixel and the second display region in the second pixel is greater than or equal to 20 μm.

3. A display module comprising:

the display device according to claim 1 ; and

a touch sensor.

4. An electronic device comprising:

the display device according to claim 1 ; and

a battery.

5. A display device comprising:

a first pixel; and

a second pixel,

wherein the first pixel and the second pixel are adjacent to each other,

wherein each of the first pixel and the second pixel comprises a first display region, a second display region, a first display element, and a second display element,

wherein the first display region is configured to reflect incident light,

wherein the second display region is positioned inside the first display region and configured to emit light,

wherein the first display element overlaps with the first display region,

wherein the second display element overlaps with the second display region, and

wherein a position of the second display region inside the first display region in the first pixel and a position of the second display region inside the first display region in the second pixel are different from each other.

6. The display device according to claim 5 ,

wherein the first display element comprises a liquid crystal layer, and

wherein the second display element comprises a light-emitting layer.

7. The display device according to claim 5 ,

wherein colors of light emitted from the second display element in the first pixel and the second display element in the second pixel are different.

8. The display device according to claim 5 ,

wherein the first display element and the second display element are connected to different transistors and independently controlled.

9. The display device according to claim 8 ,

wherein each of the transistors comprises an oxide semiconductor film in a channel region.

10. The display device according to claim 5 ,

wherein an interval between the second display region in the first pixel and the second display region in the second pixel is greater than or equal to 20 μm.

11. A display module comprising:

the display device according to claim 5 ; and

a touch sensor.

12. An electronic device comprising:

the display device according to claim 5 ; and

a battery.

13. A display device comprising:

a first pixel; and

a second pixel,

wherein the first pixel and the second pixel are adjacent to each other,

wherein each of the first pixel and the second pixel comprises a first display element and a second display element,

wherein the first display element comprises a reflective film including an opening,

wherein the second display element comprises a light-emitting layer,

wherein the opening overlaps with the light-emitting layer, and

wherein a position of the opening in the first pixel and a position of the opening in the second pixel are different from each other.

14. The display device according to claim 13 ,

wherein the first display element comprises a liquid crystal layer.

15. The display device according to claim 13 ,

wherein colors of light emitted from the second display element in the first pixel and the second display element in the second pixel are different.
