Disclosed are a light emitting device and an electronic device including the same. In the light emitting device: a) an absolute value of a lowest unoccupied molecular orbital (LUMO) energy level of a first electron transport compound (ET-1) is smaller than an absolute value of a LUMO energy level of a host compound (H-1); b) the absolute value of the LUMO level of the second electron transport compound (ET-2) is less than the absolute value of the LUMO level of the third electron transport compound (ET-3); and c) the absolute value of the LUMO level of the second electron transport compound (ET-2) is less than the absolute value of the LUMO level of the first electron transport compound (ET-1).

    公开了一种发光器件和包括发光器件的电子设备,在发光器件中:a)第一电子传输化合物(ET‑1)的最低未占分子轨道(LUMO)能级的绝对值小于主体化合物(H‑1)的LUMO能级的绝对值;b)第二电子传输化合物(ET‑2)的LUMO能级的绝对值小于第三电子传输化合物(ET‑3)的LUMO能级的绝对值;以及c)第二电子传输化合物(ET‑2)的LUMO能级的绝对值小于第一电子传输化合物(ET‑1)的LUMO能级的绝对值。
