Claim Text:
1. An organic electroluminescence device, comprising on a substrate: a pair of electrodes; at least one layer of an organic layer including a light emitting layer containing a light emitting material disposed between the electrodes, wherein the light emitting layer contains at least each one of a compound represented by the following Formula (3) and a compound represented by the following Formula (D-5): wherein Z 3 represents benzene, or biphenyl and may be further substituted by at least one group selected from the group consisting of an alkyl group, an aryl group, a silyl group, a cyano group, a fluorine atom and a combination thereof; Y 3 represents a group represented by the following Formula (15a); and n 3 represents an integer of 2: wherein R 155 represents a hydrogen atom; each of R 154 and R 156 independently represents a hydrogen atom, an alkyl group, a silyl group, a fluorine atom, a cyano group or a trifluoromethyl group, and these groups may be further substituted with at least one of an alkyl group having 1 to 6 carbon atoms and a phenyl group; R 157 represents a benzene ring, a naphthalene ring, a pyridine ring, a triazine ring or a pyrimidine ring, and these rings may be further substituted with at least one group selected from a methyl group, an isobutyl group, a t-butyl group, a neopentyl group, a phenyl group, a naphthyl group, a cyano group and a fluorine atom; and * represents a bond for linking to Z 3 : wherein each of R 3 to R 10 independently represents a hydrogen atom, an alkyl group or an aryl group; each of R 3 ′ to R 6 ′ represents a hydrogen atom, an alkyl group or an aryl group; and each of R y independently represents a hydrogen atom, an alkyl group, a perfluoroalkyl group, a halogen atom or an aryl group; wherein the compound of formula (D-5) is selected from the group consisting of:
