Organic electroluminescent element and electronic device

An organic electroluminescence device, comprising:

• an anode;
• a cathode;
• an emitting zone disposed between the anode and the cathode;
• and
• a first electron transporting layer disposed between the emitting zone and the cathode, wherein
• the emitting zone comprises a first emitting layer and a second emitting layer,
• the first emitting layer comprises a first compound as a first host material and a first emitting compound that emits light having a maximum peak wavelength of 500 nm or less,
• the second emitting layer comprises a second compound as a second host material and a second emitting compound that emits light having a maximum peak wavelength of 500 nm or less,
• the first host material and the second host material are mutually different,
• the first emitting compound and the second emitting compound are mutually the same or different,
• a triplet energy of the first host material T1(H1) and a triplet energy of the second host material T1(H2) satisfy a relationship of a numerical formula (Numerical Formula 1A) below,
• the first electron transporting layer comprises a third compound,
• the third compound is a pyrimidine compound, and
• a difference between an affinity value of the third compound Af(M3) and an affinity value of the host material comprised in the emitting layer that is disposed closer to the cathode and is either the first emitting layer or the second emitting layer Af(HX) satisfies a relationship of a numerical formula (Numerical Formula 2B) below,
