ORGANIC ELECTROLUMINESCENT ELEMENT, DISPLAY DEVICE AND LIGHTING DEVICE

摘要

Provided is an organic electroluminescent element comprising a substrate having thereon an anode, a cathode, and a plurality of organic layers sandwiched between the anode and the cathode,
wherein the plurality of organic layers comprise:
a light emitting layer containing a phosphorescence emitting compound; and
an electron transport layer containing a compound represented by Formula (1),
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒFormula (1) (Ar1)n1-Y1
wherein n1 is an integer of 1 or more; Y 1 is a substituent when n1 is 1, and Y 1 is a single bond or a linking group of n1 valences when n1 is two or more; Ar1 is a group represented by Formula (A), a plurality of Ar1 may be the same or different with each other when n1 is two or more; and the compound represented by Formula (1) contains at least two condensed aromatic heterocyclic rings each comprising 3 or more rings condensed with each other:
