摘要： To provide a light-emitting element whose power efficiency is improved and which emits light of natural color like light bulb color. In the light-emitting element, at least three light-emitting units are stacked. The emission spectrum of the light-emitting element has two peaks. One of the two peaks is obtained by combining spectra of light emitted from two light-emitting units. The peak is in the yellow to orange wavelength range and has a wavelength greater than or equal to 560 nm and less than 580 nm. Thus, a wavelength range of high luminosity can be used and the power efficiency can be improved. The color of light emitted from the light-emitting element is close to a blackbody locus in a chromaticity diagram, and light of natural color like light bulb color can be achieved.

Further, there are various different kinds of white light; however, in particular, an object is to provide a white light-emitting element which emits white light which is close to the standard white color of the NTSC. Over a substrate 100, a second light-emitting element 110 and a first light-emitting element 120 are stacked in series. The first light-emitting element 120 exhibits a light emission spectrum having two peaks (two peaks in the blue to green wavelength range) and is disposed close to a film of light-reflecting material. The second light-emitting element 110 exhibits a light emission spectrum having a peak in the orange to red wavelength range, and is disposed in a position which is not close to the film of light-reflecting material.

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 positioned to the electrode having a reflective property, the shorter the wavelength of light emitted from the light-emitting layer is.
