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; and
a second absorption layer,
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 stacked layer,
wherein the stacked layer comprises a first light-emitting layer comprising a fluorescent substance that emits blue light and a second light-emitting layer comprising a material other than a fluorescent substance,
wherein the first color conversion layer comprises a first quantum dot which converts blue light into green light,
