Organic electric-field light-emitting element, light-emitting material for organic electric-field light-emitting element, and light-emitting device, display device, and illumination device using same element

An organic electroluminescent element having

• a substrate,
• a pair of electrodes disposed on this substrate and including an anode and a cathode, and a single or a plurality of organic layers disposed between these electrodes, wherein
• said organic layer(s) include a light-emitting layer, and this light-emitting layer contains a host material and at least one light-emitting material expressed by General Formula 1 below:
• n1 represents an integer from 0 to 8;
• the R1 groups each independently represents a substituent substituted for a hydrogen atom of the pyrene skeleton, with the proviso that if n1 is 2 or greater, adjacent R1 groups are not linked to each other to form a saturated or unsaturated ring;
• X represents CRaRb, wherein Ra and Rb each independently represents a hydrogen atom or a substituent, and Ra and Rb may jointly form a five- or six-membered ring, NRc, wherein Rc represents a hydrogen atom or a substituent, O, S, or SiRdRe, wherein Rd and Re each independently represents a hydrogen atom or a substituent, and Rd and Re may jointly form a five- or six-membered ring;
• and A1 to A4 each independently represents either N or CRf, wherein Rf represents a hydrogen atom or a substituent, and two adjacent Rf groups may jointly form a saturated or unsaturated ring, but no more than two rings may be formed jointly by two or more of the Rf groups.
