    摘要： A top emission organic EL device includes an anode, hole transporting zone, emitting layer, electron transporting zone, and cathode in this order. The hole transporting zone includes: a first layer interposed between the anode and the emitting layer; and a second layer interposed between the first layer and the emitting layer. The first layer contains a first compound and the second layer contains a second compound. A film thickness of the first layer and the second layer satisfies a formula (1) and (2), respectively. A hole mobility μH1 of the first compound satisfies a formula (3) and a hole mobility μH2 of the second compound satisfies a formula (4), 100 nm≤d1≤300 nm  (1) 1 nm≤d2≤20 nm  (2) 1.0×10−4 [cm2/Vs]≤μH1≤1.0×10−1 [cm2/Vs]  (3) 1.0×10−10 [cm2/Vs]≤μH2≤1.0×10−6 [cm2/Vs]  (4).
