1: An organic electroluminescence device, comprising:
an anode; an emitting layer; and a cathode, the emitting layer comprising a first material, a second material and a third material, the first material being a fluorescent material, the second material being a delayed fluorescent material, the third material having a singlet energy larger than a singlet energy of the second material, wherein an energy gap Eg77K(M2) at 77 [K] of the second material is larger than an energy gap Eg77K(M1) at 77 [K] of the first material, and wherein an energy gap Eg77K(M3) at 77 [K] of the third material is larger than the energy gap Eg77K(M2) at 77 [K] of the second material. |
