1. A light-emitting device comprising:
a first display element;
a second display element;
a third display element;
a first color conversion layer;
a second color conversion layer;
a first absorption layer;
a second absorption layer; and
an insulating film,
wherein the first absorption layer and the first display element overlap with each other with the first color conversion layer interposed between the first absorption layer and the first display element,
wherein the second absorption layer and the second display element overlap with each other with the second color conversion layer interposed between the second absorption layer and the second display element,
wherein each of the first display element, the second display element, and the third display element comprises a first light-emitting unit, a second light-emitting unit, and an intermediate layer between the first light-emitting unit and the second light-emitting unit,
wherein the first light-emitting unit comprises a material that emits blue light,
wherein the second light-emitting unit comprises the material that emits blue light,
wherein each of the first display element, the second display element, and the third display element emits first light,
wherein the first color conversion layer converts the first light into second light,
wherein the second color conversion layer converts the first light into third light,
wherein the first light emitted from the third display element does not enter a color conversion layer,
wherein a wavelength of the second light is longer than a wavelength of the first light,
wherein a wavelength of the third light is longer than the wavelength of the first light, and
wherein the insulating film is between the first color conversion layer and the second color conversion layer.
