    摘要: A light-emitting element with which a reduction in power consumption and an improvement in productivity of a display device can be achieved is provided. A technique of manufacturing a display device with high productivity is provided. The light-emitting element includes an electrode having a reflective property, and a first light-emitting layer, a charge generation layer, a second light-emitting layer, and an electrode having a light-transmitting property stacked in this order over the electrode having a reflective property. The optical path length between the electrode having a reflective property and the first light-emitting layer is one-quarter of the peak wavelength of the emission spectrum of the first light-emitting layer. The optical path length between the electrode having a reflective property and the second light-emitting layer is three-quarters of the peak wavelength of the emission spectrum of the second light-emitting layer.

    摘要: A light-emitting element includes a light-emitting layer having a two-layer structure in which a first light-emitting layer containing a first light-emitting substance and a second light-emitting layer containing a second light-emitting substance, which is in contact with the first light-emitting layer, are provided between an anode and a cathode. The first light-emitting layer is separated into two layers of a layer provided on the anode side and a layer provided on the cathode side. The layer provided on the anode side contains only a first light-emitting substance, or a first organic compound of less than 50 wt % and the first light-emitting substance of 50 wt % to 100 wt %. The layer provided on the cathode side contains a second organic compound and the first light-emitting substance. The second light-emitting layer, which is provided in contact with the first light-emitting layer, contains the second light-emitting substance and a third organic compound.

    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.
