Abstract
An organic electroluminescence device emitting white light which emits white light and exhibits properties sufficient for practical applications, i.e., a high efficiency of light emission and a long life, is provided. The organic electroluminescence device emitting white light 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 a fluoranthene skeleton structure, a pentacene skeleton structure and a perylene skeleton structure.

30. An organic electroluminescence device comprising 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 material emitting blue light and a fluorescent compound having a perylene skeleton structure represented by the following general formula [12] or [13]: wherein X1 to X16 in formula [12] and X1 to X14 in formula [13] each independently represent;
a hydrogen atom;
a linear, branched or cyclic alkyl group having 1-20 carbon atoms;
a linear, branched or cyclic alkoxy group having 1-20 carbon atoms;
a substituted or unsubstituted aryl group having 6-30 carbon atoms;
a substituted or unsubstituted aryloxy group having 6-30 carbon atoms;
a substituted or unsubstituted arylamino group having 6-30 carbon atoms;
a substituted or unsubstituted alkylamino group having 1-30 carbon atoms;
a substituted or unsubstituted arylalkylamino group having 7-30 carbon atoms;
or a substituted or unsubstituted alkenyl group having 8-30 carbon atoms, adjacent substituents and adjacent groups represented by X1 to X16 in formula [12] and X1 to X14 in formula [13] may be bonded to each other to form a cyclic structure, and when the adjacent substituents are aromatic groups, the substituents may be the same group, and wherein the fluorescent compound has a peak wavelength of fluorescence at 540 nm to 650 nm.- View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
