Organic electroluminescent element, and light emitting device, display device and lighting device each using organic electroluminescent element

An organic electroluminescent element comprising:

• a substrate;
• a pair of electrodes including an anode and a cathode, disposed on the substrate;
• and
• at least one organic layer including a light emitting layer, disposed between the electrodes,
• wherein the light emitting layer contains at least one kind of light emitting material represented by the following general formula (1) and at least one kind of host material represented by the following general formulae (H-2) or (H-5):
• L represents O, NRC0, or CRC1RC2;
• RC0 to RC2 each independently represents a substituent selected from the group consisting of a C1-10 alkyl group and a C6-12 aryl group wherein two C6-12 aryl groups may be bonded to form a fused ring;
• RC3 to RC6 each independently represents a substituent selected from the group consisting of a C1-10 alkyl group, a C6-12 aryl group, and a cyano group;
• nC3 and nC6 each independently represents an integer of 0 to 3, and nC4 and nC5 each independently represents an integer of 0 to 4;
• wherein when nC3 to nC6 are 2 or more, a plurality of RC3s to RC6s may be respectively the same as or different from each other:
• wherein RH211 to RH214, RH220, RH221, and RH222 to RH225 are each a hydrogen atom;
• RH215 to RH219 is each independently selected from the group consisting of a hydrogen atom, a C6-12 aryl group, a C3-12 aromatic heterocyclic group, and combinations thereof;
• XH2 represents either of O and S:
• wherein RH511 to RH525 are each a hydrogen atom;
• XH5 represents NRH526;
• and
• RH526 represents a substituent selected from the group consisting of a C6-12 aryl group, a C3-24 aromatic heterocyclic group, and combinations thereof.
