<p>An organic electroluminescence device comprising an organic compound layer including at least an organic light-emitting layer sandwiched by a pair of electrodes, i.e. an anode and a cathode, wherein the organic compound layer contains a light-emitting material and a bis-condensation aromatic cyclic compound. Crystallization is suppressed even after a long time driving or in a high temperature environment, and a practical organic EL device having enhanced durability is provided.</p> |
