Display panel, display device, input/output device, and data processing device

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 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 the first color conversion layer comprises a first quantum dot which converts blue light into green light,
• wherein the second color conversion layer comprises a second quantum dot which converts blue light into red light,
• wherein blue light emitted from the third display element does not enter a color conversion layer,
• wherein the first absorption layer absorbs blue light, blue light included in external light, and red light included in external light, and
• wherein the second absorption layer absorbs blue light and green light.
