Patent ID: 8367224

Claim:
An organic electroluminescence element comprising an anode, a cathode and a plurality of organic compound layers between the anode and the cathode, provided that one of the organic compound layers is a light emitting layer containing a phosphorescence emitting compound, wherein at least one of the organic compound layers contains a compound represented by Formula (1), wherein, X represents O or S; Y 1 to Y 3 each represents a hydrogen atom, a substituent or a group represented by Formula (A), provided that at least two of Y 1 to Y 3 are groups represented by Formula (A), not all of Y 1 to Y 3 are the same group, and at least one of the groups represented by Formula (A) has Ar of a carbazolyl group, or an azacarbazolyl group containing 2 to 5 nitrogen atoms, wherein, L represents a divalent linking group derived from an aromatic hydrocarbon ring or an aromatic heterocycle; n represents an integer of 0 to 3, provided that when n is 2 or 3, a plurality of ns may be the same or different; “*” indicates a linking position with Formula (1); and Ar represents a group represented by Formula (A′), wherein, X 0 represents N(R), O or S; E 1 to E 8 each represents C(R 1 ), or N, provided that R and R 1 each represents a hydrogen atom, a substituent or a linking position with L; and “**” indicates a linking position with L.
