Organic electroluminescence device

An organic electroluminescence device, comprising:

• a pair of electrodes composed of an anode and a cathode;
• a light emitting layer between the electrodes;
• and
• an organic layer which is adjacent to the light emitting layer between the light emitting layer and the cathode, on a substrate,
• wherein the light emitting layer comprises at least one compound represented by the following Formula (1), and
• the organic layer adjacent to the light emitting layer comprises at least one hydrocarbon compound which is composed only of carbon atoms and hydrogen atoms represented by Formula (An-1);
• in Formula (1),
• R1 represents an alkyl group, an aryl group or a silyl group, and may further have a substituent Z, provided that R1 does not represent a carbazolyl group and a perfluoroalkyl group,
• in the case where R1 is present in plurality, each of a plurality of R1 may be the same or different,
• a plurality of R1 may be bonded to each other to form an aryl ring which may have substituent Z,
• each of R2 to R5 independently represents an alkyl group, an aryl group, a silyl group, a cyano group or a fluorine atom, and may further have a substituent Z,
• in the case where each of R2 to R5 is present in plurality, each of a plurality of R2 to R5 may be the same or different,
• the substituent Z represents an alkyl group, an alkenyl group, a phenyl group, an aromatic heterocyclic group, an alkoxy group, a phenoxy group, a fluorine atom, a silyl group, an amino group, a cyano group or a group formed by combining these groups, and a plurality of the substituents Z may be bonded to each other to form an aryl ring,
• n1 represents an integer of 1 to 5,
• each of n2 to n5 independently represents an integer of 0 to 4
• in Formula (An-1),
• each of Ar1 and Ar2 independently represents an aryl group,
• each of R12 to R19 independently represents a hydrogen atom, an alkyl group or an aryl group,
• R12 and R13, R13 and R14, R14 and R15, R16 and R17, R17 and R18, and R18 and R19 may be bonded to each other to form a ring.
