Organic electroluminescence device emitting white light
First Claim
1. An organic electroluminescence device which comprises a pair of electrodes and a layer of a light emitting medium disposed between the pair of electrodes, wherein the layer of a light emitting medium comprises a light emitting material emitting blue light and a fluorescent compound having at least one structure selected from (1) a fluoranthene skeleton structure and (2) a pentacene skeleton structure which is substituted with at least one group selected from a substituted or unsubstituted aryl group having 6 to 30 carbon atoms and a substituted or unsubstituted heterocyclic group having 5 to 30 carbon atoms, at the positions 6 and 13, respectively.
