Abstract:
1. A display device comprising: a first substrate; a first light-emitting element over the first substrate; a second light-emitting element over the first substrate; a third light-emitting element over the first substrate; a first color filter layer having a transmission center wavelength in a green wavelength region, the first color filter layer overlaps with the second light-emitting element; a second color filter layer having a transmission center wavelength in a red wavelength region, the second color filter layer overlaps with the third light-emitting element; and a second substrate over the first light-emitting element, the second light-emitting element, and the third light-emitting element, wherein the first light-emitting element, the second light-emitting element, and the third light-emitting element each comprises: wherein emission colors of the first light-emitting layer, the second light-emitting layer, and the third light-emitting layer are different from each other, wherein a color filter layer overlapping with the first light-emitting element is not provided, wherein a distance between the reflective electrode and the light-transmitting electrode of the first light-emitting element, a distance between the reflective electrode and the light-transmitting electrode of the second light-emitting element, and a distance between the reflective electrode and the light-transmitting electrode of the third light-emitting element are different from each other, and wherein the first light-emitting element, the second light-emitting element, and the third light-emitting element each comprises a layer including an organic compound between the first light-emitting layer and the second light-emitting layer.
