ABSTRACT:
An electroluminescent element includes host materials and guest materials in a part of an electroluminescent layer. Device characteristics (luminous efficiency, luminous characteristics, or the like) of the electroluminescent element is improved by using host materials and guest materials with a common skeleton (represented by the following general formula 14) for an electroluminescent layer interposed between a pair of electrodes in the electroluminescent element.In general formula 14, X1to X3, each of which may be the same or different, are individually a hydrogen atom, a halogen atom, a lower alkyl group, an alkoxy group, an acyl group, a nitro group, a cyano group, an amino group, a dialkylamino group, a diarylamino group, a vinyl group which may have a substituent, an aryl group which may have a substituent, or a heterocyclic group which may have a substituent.
