Abstract:
A technique of manufacturing a display device with high productivity is provided. In addition, a high-definition display device with high color purity is provided. By adjusting the optical path length between an electrode having a reflective property and a light-emitting layer by the central wavelength of a wavelength range of light passing through a color filter layer, the high-definition display device with high color purity is provided without performing selective deposition of light-emitting layers. In a light-emitting element, a plurality of light-emitting layers emitting light of different colors are stacked. The closer the light-emitting layer is positioned to the electrode having a reflective property, the shorter the wavelength of light emitted from the light-emitting layer is.

Claim (Index 8):
A display device comprising:\n a first light-emitting element comprising:\n a first electrode that is reflective; \n a first light-emitting layer; \n a second light-emitting layer over the first light-emitting layer; \n a third light-emitting layer over the second light-emitting layer; and \n a second electrode; \n a second light-emitting element comprising:\n a third electrode that is reflective; \n the first light-emitting layer; \n the second light-emitting layer over the first light-emitting layer; \n the third light-emitting layer over the second light-emitting layer; and \n the second electrode; \n a third light-emitting element comprising:\n a fourth electrode that is reflective; \n the first light-emitting layer; \n the second light-emitting layer over the first light-emitting layer; \n the third light-emitting layer over the second light-emitting layer; and \n the second electrode over the third light-emitting layer; \n a first color filter overlapping with the first light-emitting element and having a first central wavelength of a first wavelength range in which the first color filter has a transmittance of 50% or higher in a visible wavelength range; a second color filter overlapping with the second light-emitting element and having a second central wavelength of a second wavelength range in which the second color filter has a transmittance of 50% or higher in the visible light range; and a third color filter overlapping with the third light-emitting element and having a third central wavelength of a third wavelength range in which the third color filter has a transmittance of 50% or higher in the visible wavelength range, wherein the first wavelength range is different from the second wavelength range, wherein the first central wavelength, the second central wavelength, and the third central wavelength are different from one another, and wherein a first optical path length between the first light-emitting layer and the first electrode is different from a second optical path length between the second light-emitting layer and the third electrode in accordance with the difference between the first central wavelength and the second central wavelength.
