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 (40)

1 . A display device comprising:

a first display region, a second display region, a third display region, and a fourth display region,

wherein the first display region, the second display region, the third display region, and the fourth display region are substantially quadrilaterals,

wherein the first display region, the second display region, and the fourth display region comprise a first driver circuit,

wherein the third display region comprises a second driver circuit,

wherein the first display region comprises a first side and a second side perpendicular to the first side,

wherein the second display region comprises a third side, a fourth side perpendicular to the third side, and a fifth side opposite the third side,

wherein the third display region comprises a sixth side and a seventh side perpendicular to the sixth side,

wherein the fourth display region comprises an eighth side, a ninth side perpendicular to the eighth side, and a tenth side opposite the eighth side,

wherein the first side and the third side comprise a region in contact with each other,

wherein the second side and the sixth side comprise a region in contact with each other,

wherein the fourth side and the eighth side comprise a region in contact with each other,

wherein the seventh side and the tenth side comprise a region in contact with each other,

wherein a length of the fourth side is greater than a length of the eighth side,

wherein a length of the seventh side is greater than a length of the tenth side,

wherein the first driver circuit is positioned along the fifth side and the ninth side,

wherein the second driver circuit is positioned along the seventh side,

wherein the second display region, the third display region, and the fourth display region comprise curved surfaces.

2 . The display device according to claim 1 ,

wherein the fourth display region comprises a region overlapping with the second driver circuit.

3 . A display device comprising:

a first display region, a second display region, a third display region, and a fourth display region,

wherein the first display region, the second display region, the third display region, and the fourth display region are substantially quadrilaterals,

wherein a first driver circuit is configured to drive pixels in the first display region, the second display region, and the fourth display region,

wherein a second driver circuit is configured to drive pixels in the third display region,
