(57) [Problem] To provide an electroluminescent device using functional molecules having hole transporting property, light emitting property and electron transporting property provided with high heat resistance and low crystallinity. SOLUTION: One or more organic compound layers 14 are provided between a first electrode 12 and a second electrode 16, and at least one of the organic compound layers 14 includes a condensed ring compound derivative represented by the following chemical formula. Has become. Embedded image Here, A1 and A2 are substituents, B1 to B6 are directly bonded or bifunctional substituents, and R1 and R2 are hole transporting and luminescent properties of triphenylamine, coumarin, oxadiazole derivatives and the like. , A functional unit having each function of electron transportability. |
