Organic electroluminescent element, illuminator and display

An organic electroluminescent element comprising an anode, a cathode and light emitting layer disposed between the anode and the cathode, wherein the light emitting layer comprises (i) a guest compound selected from the group consisting of

• wherein Ra represents an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an aromatic hydrocarbon group, an aromatic heterocyclic group or a heterocyclic group, Rb, Rc, Rb1 and Rc1 each represent a hydrogen atom or a substituent, and A1 represents a group of atoms necessary to form an aromatic hydrocarbon ring or an aromatic heterocycle,
• and (ii) a host compound represented by the following Formula (1):
• wherein Ra1 represents a carbazolyl group, R1 and R2 each represent a phenyl group, a pyridyl group, a pyridazinyl group, a pyrimidinyl group, a pyrazinyl group, a triazinyl group, an imidazolyl group, a pyrazolyl group, a thiazolyl group, a quinazolinyl group or a phthalazinyl group, R5 represents an alkyl group or an aromatic hydrocarbon group, and n1, n2 and n5 each represent an integer of 0 to 4, provided that n1 and n2 are not simultaneously 0.
