A1
Abstract:
In an organic light emitting device having a composition including a first host material, a second host material having a higher HOMO energy level than the first host material, a delayed fluorescent material, and a light emitting material, high luminous efficiency can be achieved by setting EHOMO(H2)-EHOMO(T) ≤ 0.33 eV. EHOMO(H2) and EHOMO(T) are the HOMO energy levels of the second host material and delayed fluorescent material, respectively.
