    摘要: 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 to the electrode having a reflective property, the longer the wavelength of light emitted from the light-emitting layer is.

    摘要: A layer including an organic compound at least includes a layer serving as a light-emitting layer in which a first layer, a second layer, a third layer, and a fourth layer are stacked in that order over an anode. The first layer includes a first light-emitting substance, the second layer includes a second light-emitting substance, the third layer includes a third light-emitting substance, and the fourth layer includes a fourth light-emitting substance. Emission peak wavelengths of the first light-emitting substance and the fourth light-emitting substance are shorter than an emission peak wavelength of the third light-emitting substance, and the emission peak wavelength of the third light-emitting substance is shorter than an emission peak wavelength of the second light-emitting substance. Each of the first layer, the second layer, and the third layer has a hole-transporting property, and the fourth layer has an electron-transporting property.
