An organic electroluminescence device having a layer of an organicnlight emitting medium which comprises (A) a specific arylamine compoundnand (B) at least one compound selected from specific anthracenenderivatives, spirofluorene derivatives, compounds having condensed ringsnand metal complex compounds and is disposed between a pair of electrodesnand an organic light emitting medium comprising the above componentsn(A) and (B) are provided. The organic electroluminescence device exhibitsna high purity of color, has excellent heat resistance and a long life andnefficiently emits bluish to yellowish light. The organic light emittingnmedium can be advantageously used for the organic electroluminescencendevice. |
