Patent ID: 8187728

Claim:
An organic electroluminescent device having an anode, a cathode, and at least one organic layer including a light-emitting layer provided between said anode and said cathode, wherein said organic layer includes an amine compound represented by the following formula (1): wherein Ar 1 to Ar 4 each independently represent a carbocyclic aromatic group having a total carbon number of from 6 to 20 or a heterocyclic aromatic group having a total carbon number of from 3 to 20; an organic electroluminescent device having an anode, a cathode, and at least one organic layer including a light-emitting layer provided between said anode and said cathode, wherein said organic layer includes an amine compound represented by the following formula (1): R1 and R2 each independently represent a halogen atom, a hydroxyl group, a substituted or unsubstituted carbonyl group having a carbon number of from 1 to 20, a substituted or unsubstituted carbonyl ester group having a carbon number of from 1 to 20, a substituted or unsubstituted alkenyl group having a carbon number of from 2 to 20, a cyano group, a nitro group or a heterocyclic aromatic group having a total carbon number of from 3 to 20; and n stands for an integer of 1, 2 or 3, and wherein a combination of At1 and Ar2 is the same as a combination of Ar3 and Ar4.
