Abstract:
An object is to provide a light-emitting element which uses a plurality of kinds of light-emitting dopants and has high emission efficiency. In one embodiment of the present invention, a light-emitting device, a light-emitting module, a light-emitting display device, an electronic device, and a lighting device each having reduced power consumption by using the above light-emitting element are provided. Attention is paid to Förster mechanism, which is one of mechanisms of intermolecular energy transfer. Efficient energy transfer by Förster mechanism is achieved by making an emission wavelength of a molecule which donates energy overlap with the longest-wavelength-side local maximum peak of a graph obtained by multiplying an absorption spectrum of a molecule which receives energy by a wavelength raised to the fourth power.

Claim (Index 2):
A light-emitting element comprising:\n a first electrode; an EL layer over the first electrode, the EL layer comprising:\n a first light-emitting layer comprising:\n a first phosphorescent compound; \n a first host material; and \n a first organic compound; and \n \n a second light-emitting layer comprising:\n a second phosphorescent compound; and \n a second host material; and \n \n a second electrode over the EL layer, wherein the first host material and the first organic compound are capable of forming an exciplex therebetween, wherein light emitted from the first phosphorescent compound has a longer wavelength than light emitted from the exciplex, wherein a longest-wavelength-side peak of a function \u03b5(\u03bb)\u03bb 4  of the second phosphorescent compound overlaps with a photoluminescence spectrum F(\u03bb) of the first phosphorescent compound, wherein \u03bb denotes a wavelength, and wherein \u03b5(\u03bb) denotes a molar absorption coefficient at the wavelength \u03bb.
