Patent ID: 8592057

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 (2): wherein, X represents O or S; three of Y 1 to Y 4 each are a group represented by Formula (2A), and one of Y 1 to Y 4 is a hydrogen atom, Ar 1 L 1 n 1* Formula (2A) wherein, L 1 represents a divalent linking group derived from an aromatic hydrocarbon ring or an aromatic heterocycle; n 1 represents an integer of 0 to 3, provided that when n 1 is 2 or 3, a plurality of L 1 s may be the same or different; “*” indicates a linking position with Formula (2); and Ar 1 is a group represented by Formula (2A′) or a carbazolyl group which may have a substituent, provided that at least one of the groups represented by Formula (2A) has a substituted carbazolyl group bonded to L 1 through a nitrogen atom: wherein, X 1 represents O or S; E 11 to E 18 each represents C(R 11 ), or N, provided that R 11 represents a hydrogen atom, a substituent or a linking position with L 1 ; and “**” indicates a linking position with L 1 .
