Abstract:
An organic electroluminescence element includes: an anode; a cathode; and a luminous layer. The luminous layer includes: a luminescent dopant having a reorganization energy of 0 eV to 0.7 eV in electron transition from a ground state (S0) to a lowest excited triplet state (T1); and a host compound having a reorganization energy of 0 eV to 0.3 eV in electron transfer reaction between a ground state (S0) and an anionic radical state (AR), and having a molecular weight within a range of 500 to 3000.
