Claim 8:
9. The organic electroluminescent device according to claim 1, wherein the second organic compound is represented by the following formula (131):, wherein from 0 to 1 of R1 to R5 represents a cyano group, from 1 to 5 of R1 to R5 each represent a group represented by the following formula (132), and the balance of R1 to R5 each represent a hydrogen atom or a substituent other than the above,, wherein R11 to R20 each independently represent a hydrogen atom or a substituent, in which R11 and R12, R12 and R13, R13 and R14, R14 and R15, R15 and R16, R16 and R17, R17 and R18, R18 and R19, and R19 and R20 each may be bonded to each other to form a ring structure; L12 represents a substituted or unsubstituted arylene group or a substituted or unsubstituted heteroarylene group, and
all or a part of the hydrogen atoms in the formula (131) may be 2H,
the substituent for the balance of R1 to R5 in the formula (131) and the substituent for R11 to R20 in the formula (132) are independently selected from the group consisting of a hydroxyl group, a halogen atom, a cyano group, an alkyl group having from 1 to 20 carbon atoms, an alkoxy group having from 1 to 20 carbon atoms, an alkylthio group having from 1 to 20 carbon atoms, an alkyl-substituted amino group having from 1 to 20 carbon atoms, an aryl-substituted amino group having from 12 to 40 carbon atoms, an acyl group having from 2 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a heteroaryl group having from 3 to 40 carbon atoms, a substituted or unsubstituted carbazolyl group having from 12 to 40 carbon atoms, an alkenyl group having from 2 to 10 carbon atoms, an alkynyl group having from 2 to 10 carbon atoms, an alkoxycarbonyl group having from 2 to 10 carbon atoms, an alkylsulfonyl group having from 1 to 10 carbon atoms, a haloalkyl group having from 1 to 10 carbon atoms, an amide group, an alkylamide group having from 2 to 10 carbon atoms, a trialkylsilyl group having from 3 to 20 carbon atoms, a trialkylsilylalkyl group having from 4 to 20 carbon atoms, a trialkylsilylalkenyl group having from 5 to 20 carbon atoms, a trialkylsilylalkynyl group having from 5 to 20 carbon atoms, and a nitro group.
