Claim Text:
1. An organic electroluminescence device comprising: a cathode; an anode; and an organic layer being interposed between the cathode and the anode, the organic layer comprising one or more layers comprising at least an emitting layer, wherein the emitting layer comprises: an anthracene derivative represented by a formula (1) below; and a pyrene derivative represented by a formula (21) below, where: a variable number c of R the rest of R the linking group is any one of an (a+1)-valent residue obtained by removing a variable number (a+1) of hydrogen atoms from a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, an (a+1)-valent residue obtained by removing a variable number (a+1) of hydrogen atoms from a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, and an (a+1)-valent residue obtained by removing a variable number (a+1) of hydrogen atoms from a group formed by bonding two to four of the substituted or unsubstituted aromatic hydrocarbon groups having 6 to 30 ring carbon atoms and the substituted or unsubstituted heterocyclic groups having 5 to 30 ring atoms; a, b and c each represent an integer of 1 to 4; and Z where: X R adjacent two substituents of at least one pair of R where: y y R X one of the rest of R where: R Ar at least one of Ar where: R each pair of R X y
