Display device

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/m2 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.
