Abstract
Disclosed are an electroluminescent element, a display device and a method for preparing the electroluminescent element. The electroluminescent element comprises a substrate () and an anode layer (), a light-emitting layer () and a cathode layer () that are disposed in sequence on the substrate (). At least one insertion layer () for adjusting electron mobility is disposed within the light-emitting layer (). By disposing an insertion layer () in the light-emitting layer (), the effect of a voltage on the recombination of electrons and holes in the light-emitting layer () can be reduced, the level of the recombination of carriers such as electrons and holes in the light-emitting layer () can be increased, and the ratio of electrons and holes that are combined can be increased.
