In an electroluminescent device comprising an anode, a cathode, and an electroluminescent organic layer interposed therebetween, wherein a luminescent material in the organic layer emits light upon application of a voltage between the anode and the cathode, an auxiliary carrier transporting layer which contains an aromatic amine derivative comprising recurring units of formula (1) and having a number average molecular weight of 200-100,000 is formed between the anode and the organic layer. R1 to R4 each are hydrogen, hydroxyl, substituted or unsubstituted monovalent hydrocarbon, organooxy, acyl or sulfonate group, excluding the case where all R1 to R4 are hydrogen atoms at the same time, and n is a positive number of 2-3,000.
An electroluminescent device comprising an anode, a cathode, and at least one electroluminescent organic layer interposed therebetween, wherein a luminescent material in said organic layer emits light upon application of a voltage between the anode and the cathode, and wherein an auxiliary carrier transporting layer which contains an aromatic amine derivative comprising recurring units of the following general formula (1) and having a number average molecular weight of 250 to 100,000 is formed between said anode and said organic layer,
