Abstract

The invention provides a quantum dot display substrate and a production method thereof and a display device, and belongs to the technical field of display. The quantum dot display substrate comprisesa driving substrate, a driving electrode located on the driving substrate, a light emitting diode connected with the driving electrode, at least two optical medium layers located on a light outlet side of the light emitting diode, and a quantum dot layer located on the light outlet side of the optical medium layers, wherein light outlet surfaces, away from the driving substrate, of the optical medium layers are cambered surfaces, and the refractive indexes of the two optical medium layers decrease gradually in a direction from positions close to the driving substrate to positions away from thedriving substrate. According to the technical scheme, the luminous efficiency of the quantum dot display substrate can be improved.
