Classification: CPC G  H | IPC H

Claim 0:
1. An organic light-emitting element comprising:
a first electrode that functions as a positive electrode;
a second electrode that functions as a negative electrode;
an organic light-emitting layer which is disposed between the first electrode and the second electrode and which is configured so that separation of charges occurs due to incidence of excited light therein; and
at least one of a charge inflow blocking layer that is disposed between the first electrode and the organic light-emitting layer and blocks inflow of holes from the first electrode to the organic light-emitting layer, and a charge inflow blocking layer that is disposed between the second electrode and the organic light-emitting layer and blocks inflow of electrons from the second electrode to the organic light-emitting layer, wherein
the charge inflow blocking layer disposed between the first electrode and the organic light-emitting layer has a HOMO level deeper than a HOMO level of organic light emitters included in the organic light-emitting layer,
the charge inflow blocking layer disposed between the second electrode and the organic light-emitting layer has a LUMO level shallower than a LUMO level of the organic light emitters, and
a dipole moment of the organic light emitters is 3 D or greater.
