An organic compound represented by formula [1] is provided.
Ring A is a polycyclic aromatic hydrocarbon ring having a fluoranthene skeleton and having 16 to 60 carbon atoms and optionally has, as a substituent, a substituted or unsubstituted alkyl group or the like. Rings B
1
and B
2
are aromatic hydrocarbon rings having 6 to 18 carbon atoms and each have two or more electron withdrawing groups. Q
1
and Q
2
respectively represent one of the electron withdrawing groups of the ring B
1
and one of the electron withdrawing groups of the ring B
2
, and are respectively located at an ortho position of the ring B
1
and at an ortho position of the ring B
2
with respect to the ring A.
A light-emitting element includes an EL layer between a pair of electrodes. The EL layer contains a first compound and a second compound. The first compound is a phosphorescent iridium metal complex having a LUMO level of greater than or equal to −3.5 eV and less than or equal to −2.5 eV, and the second compound is an organic compound having a pyrimidine skeleton. The light-emitting element includes an EL layer between a pair of electrodes. The EL layer contains a first compound and a second compound. The first compound is a phosphorescent iridium metal complex having a diazine skeleton, and the second compound is an organic compound having a pyrimidine skeleton.
