Abstract

Claims (76)

1 . A display device comprising:

a first layer;

a second layer over the first layer; and

a third layer over the second layer,

wherein the first layer comprises a first transistor comprising silicon in a channel formation region,

wherein the second layer comprises a second transistor comprising a metal oxide in a channel formation region,

wherein the third layer comprises:

a first light-emitting element;

a second light-emitting element;

a third light-emitting element;

an EL layer shared by the first light-emitting element, the second light-emitting element, and the third light-emitting element;

a first coloring layer over the first light-emitting element;

a second coloring layer over the second light-emitting element; and

a third coloring layer over the third light-emitting element,

wherein the EL layer comprises a light-emitting layer exhibiting white light, and

wherein crosstalk is not observed between the second light-emitting element and the third light-emitting element.

2 . The display device according to claim 1 ,

wherein the first coloring layer is configured to transmit red light,

wherein the second coloring layer is configured to transmit green light, and

wherein the third coloring layer is configured to transmit blue light.

wherein the third coloring layer is configured to transmit red light.

4 . The display device according to claim 1 ,

wherein the first coloring layer is configured to transmit blue light,

wherein the second coloring layer is configured to transmit red light, and

wherein the third coloring layer is configured to transmit green light.

5 . A display device comprising:

a first layer;

a second layer over the first layer; and

a third layer over the second layer,

wherein the first layer comprises a first transistor comprising silicon in a channel formation region,

wherein the second layer comprises a second transistor comprising a metal oxide in a channel formation region,

wherein the third layer comprises:

a first light-emitting element;

a second light-emitting element;

a third light-emitting element;

an EL layer shared by the first light-emitting element, the second light-emitting element, and the third light-emitting element;

a first coloring layer over the first light-emitting element;

a second coloring layer over the second light-emitting element; and

a third coloring layer over the third light-emitting element,

wherein the EL layer comprises a light-emitting layer exhibiting white light,

wherein crosstalk is not observed between the second light-emitting element and the third light-emitting element, and

wherein the second light-emitting element is adjacent to the third light-emitting element in a plan view.

6 . The display device according to claim 5 ,

wherein the first coloring layer is configured to transmit red light,

wherein the second coloring layer is configured to transmit green light, and

wherein the third coloring layer is configured to transmit blue light.

7 . The display device according to claim 5 ,

wherein the first coloring layer is configured to transmit green light,

wherein the second coloring layer is configured to transmit blue light, and

wherein the third coloring layer is configured to transmit red light.

8 . The display device according to claim 5 ,

wherein the first coloring layer is configured to transmit blue light,

wherein the second coloring layer is configured to transmit red light, and

wherein the third coloring layer is configured to transmit green light.

9 . A display device comprising:

a first layer;

a second layer over the first layer; and

a third layer over the second layer,

wherein the first layer comprises a first transistor comprising silicon in a channel formation region,

wherein the second layer comprises a second transistor comprising a metal oxide in a channel formation region,

wherein the third layer comprises:

a first light-emitting element;

a second light-emitting element;

a third light-emitting element;

an EL layer shared by the first light-emitting element, the second light-emitting element, and the third light-emitting element;

a first coloring layer over the first light-emitting element;

a second coloring layer over the second light-emitting element; and

a third coloring layer over the third light-emitting element,

wherein the EL layer comprises a light-emitting layer exhibiting white light,

wherein the first coloring layer is configured to transmit red light,

wherein the second coloring layer is configured to transmit green light,

wherein the third coloring layer is configured to transmit blue light, and

wherein, when the second light-emitting element emits light with brightness of a radiance higher than or equal to 0.001 W/sr/m 2 and the first light-emitting element and the third light-emitting element are set to display black, the first light-emitting element and the third light-emitting element each have a radiance lower than 0.0001 W/sr/m.
