摘要： Disclosed are an electroluminescent element, a display device and a method for preparing the electroluminescent element. The electroluminescent element comprises a substrate (101) and an anode layer (102), a light-emitting layer (103) and a cathode layer (104) that are disposed in sequence on the substrate (101). At least one insertion layer (105) for adjusting electron mobility is disposed within the light-emitting layer (103). By disposing an insertion layer (105) in the light-emitting layer (103), the effect of a voltage on the recombination of electrons and holes in the light-emitting layer (103) can be reduced, the level of the recombination of carriers such as electrons and holes in the light-emitting layer (103) can be increased, and the ratio of electrons and holes that are combined can be increased.

摘要： An organic light emitting diode display substrate includes a light emitting unit layer, a first band gap layer and a color conversion layer. The first band gap layer and the color conversion layer are on a light exit path of the light emitting unit layer. The light emitting unit layer includes first, second and third light emitting units periodically arranged on a driving substrate and emitting light of a first color. The color conversion layer converts a part of the light of the first color into light of a second color and a third color. The first band gap layer is between the light emitting unit layer and the color conversion layer. The first band gap layer transmits the light of the first color in a light exit direction, and reflects the light of the second color and the light of the third color.
