a first pixel, a second pixel, and a third pixel;

a light-emitting layer comprising a first light-emitting element disposed in the first pixel, a second light-emitting element disposed in the second pixel, and a third light-emitting element disposed in the third pixel;

color conversion layers disposed on the light-emitting layer, and comprising a first color conversion layer disposed in the first pixel, a second color conversion layer disposed in the second pixel, and a third color conversion layer disposed in the third pixel; and

color filter layers disposed on the color conversion layers, and comprising a first color filter layer disposed in the first pixel, a second color filter layer disposed in the second pixel, a third color filter layer disposed in the third pixel,

wherein the first light-emitting element and the second light-emitting element emit first light, a central wavelength range of the first light being a first wavelength,

wherein the first color conversion layer and the second color conversion layer contain color conversion particles that convert the first light into second light,

wherein a central wavelength range of the second light is a second wavelength that is longer than the first wavelength,
