Abstract
A light-emitting-diode device and a fabricating method thereof, a light emitting base plate and a light emitting apparatus. The light-emitting-diode device includes: an anode layer, a luminescent layer, a charge-carrier balancing layer, an electron transporting layer and a cathode layer that are arranged in stack; and a hole mobility of the charge-carrier balancing layer is greater than an electron mobility of the charge-carrier balancing layer, an LUMO energy level of the charge-carrier balancing layer is shallower than an LUMO energy level of the electron transporting layer, and an HOMO energy level of the charge-carrier balancing layer is shallower than an HOMO energy level of the luminescent layer.
