Display device, display module, and electronic device

A display device comprising:

• a first light-emitting device;
• a second light-emitting device;
• a third light-emitting device;
• a first coloring layer;
• a second coloring layer;
• a first insulating layer;
• and
• a second insulating layer,
• wherein the first light-emitting device comprises a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer,
• wherein the second light-emitting device comprises a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer,
• wherein the third light-emitting device comprises a third pixel electrode, a third light-emitting layer over the third pixel electrode, and the common electrode over the third light-emitting layer,
• wherein the first light-emitting layer and the second light-emitting layer comprise the same light-emitting material,
• wherein a wavelength of light emitted by the third light-emitting device is shorter than a wavelength of light emitted by the first light-emitting device and a wavelength of light emitted by the second light-emitting device,
• wherein a color of light transmitted by the first coloring layer is different from a color of light transmitted by the second coloring layer,
• wherein the first coloring layer overlaps with the first light-emitting device,
• wherein the second coloring layer overlaps with the second light-emitting device,
• wherein the first insulating layer covers a part of a top surface and a side surface of the first light-emitting layer and a part of a top surface and a side surface of the second light-emitting layer,
• wherein the second insulating layer overlaps with the part of the top surface of the first light-emitting layer and the part of the top surface of the second light-emitting layer with the first insulating layer therebetween,
• wherein the second insulating layer comprises a portion between the side surface of the first light-emitting layer and the side surface of the second light-emitting layer, and
• wherein the common electrode covers a top surface of the second insulating layer.
