Abstract
A material for organic electroluminescent display device includes a luminescent dopant part and an assist dopant part. The luminescent dopant part may have an energy of 2.6 eV or higher to 3.0 eV or lower in an excited singlet state S1 level. The assist dopant part may have an energy of 2.4 eV or higher to 3.0 eV or lower in the excited singlet state S1 level. An energy gap ΔEST between the excited singlet state S1 and an excited triplet state T1 may be 0 eV or larger to 2.0 eV or smaller.
