Abstract:
An organic EL element is provided that has a high light emission efficiency and that emits a plurality of light beams having respective wavelength ranges different from one another, the light beams including short wavelength light having a high chromaticity. An organic EL element ( 1 ) includes an exciton generating layer ( 7 ) and a guest layer ( 8 ) that are adjacent to each other.

Claim (Index 11):
The organic electroluminescent element according to  claim 1 , wherein\n the organic layer further includes a third layer containing at least one fluorescent material; the third layer is adjacent to the first layer and is present on a first side of the first layer which first side is opposite to a second side of the first layer on which second side the second layer is present; an energy level in a lowest triplet excited state in the third layer is lower than the energy level in the lowest triplet excited state in the first layer and is different from the energy level in the lowest triplet excited state in the second layer; an energy level in a lowest singlet excited state in the third layer is higher than an energy level in a lowest singlet excited state in the first layer and is different from an energy level in the lowest singlet excited state in the second layer; the third layer has a thickness of not more than 1 nm; and the organic electroluminescent element is configured to emit the light within the at least one wavelength range, the light including:\n the light within the first wavelength range which light within the first wavelength range is emitted when the exciton in the lowest singlet excited state in the second layer which exciton is generated in a case where (i) the triplet exciton generated in the first layer undergoes energy transfer to an exciton in a lowest triplet excited state in the second layer and (ii) the exciton in the lowest triplet excited state is upconverted to an exciton in a lowest singlet excited state among the molecules in the second layer changes to the ground state; \n light within a third wavelength range which light within the third wavelength range is emitted when an exciton in the lowest singlet excited state in the third layer which exciton is generated in a case where (i) the triplet exciton generated in the first layer undergoes energy transfer to an exciton in the lowest triplet excited state in the third layer and (ii) the exciton in the lowest triplet excited state is upconverted to an exciton in a lowest singlet excited state among molecules in the third layer changes to a ground state; and \n light within a second wavelength range which light within the second wavelength range is emitted when a triplet exciton generated in the first layer which triplet exciton does not undergo the energy transfer to an exciton in the lowest triplet excited state in the second layer and which triplet exciton is an exciton in the lowest triplet excited state in the first layer changes to a ground state, \n the first wavelength range being a shorter wavelength range than the third wavelength range, the third wavelength range being a shorter wavelength range than the second wavelength range.
