  • Patent number: 8810125
    Abstract: An object is to improve luminous efficiency of a light emitting element using triplet exciton energy effectively. Another object is to reduce power consumption of a light emitting element, a light emitting device, and an electronic device. Triplet exciton energy generated in a light emitting layer which exhibits short wavelength fluorescence can be effectively utilized by use of a structure in which the light emitting layers which exhibit short wavelength fluorescence are sandwiched between light emitting layers each including a phosphorescent compound. Further, the emission balance can be improved between the light emitting layer including a phosphorescent compound and the light emitting layer which exhibits fluorescence by the devising of the structure of the light emitting layer which exhibits fluorescence.
