Patent ID: 7749615

Claim:
An organic electroluminescent device, comprising: organic compound thin film layers including a luminescent layer, the organic compound thin film layers being formed between a pair of electrodes; a hole-transporting layer disposed between the luminescent layer and an anode; and an electron-transporting layer disposed between the luminescent layer and a cathode, the organic electroluminescent device having no hole-blocking layer between the electron-transporting layer and the luminescent layer, the organic electroluminescent device being characterized in that the luminescent layer contains a compound represented by the following general formula (III) as a host material and an organometal complex containing at least one metal selected from the group consisting of iridium, as a guest material: where R 1 to R 16 each independently represent hydrogen atom, alkyl group, aralkyl group, alkenyl group, cyano group, amino group, amide group, alkoxycarbonyl group, carboxyl group, alkoxy group, or aromatic group which may have a substituent.
