Organic luminescence device

摘要

An organic luminescence device is constituted by an anode and a cathode and at least one organic layer disposed between the anode and the cathode. The above-mentioned at least one organic layer includes a layer of a fused polynuclear compound represented by the following formula (I):In the above formula (I), X1, X2 and X3 may preferably be an oxygen atom or C(CN)2. The device using the fused polynuclear compound of formula (I) exhibits a high luminance luminescence characteristic for a long period of time.
