Display module, preparation method thereof and display device

Abstract

The invention provides a display module, a preparation method thereof and a display device, and solves the problem that a display module in the prior art has relatively high reflectivity and relatively low luminous efficiency. The display module comprises a substrate; the pixel defining layer is located on one side of the substrate, and a plurality of first openings are formed in the pixel defining layer; the light-emitting device is partially located in the first opening, the light-emitting device comprises a first electrode layer, a light-emitting layer and a second electrode layer which are arranged in a stacked mode, and the first electrode layer is located on the side, close to the substrate, of the second electrode layer; the first light absorption structure is located in the first electrode layer; the optical adhesive layer is located on the side, away from the substrate, of the light-emitting device, and the optical adhesive layer comprises light absorption particles. The display module provided by the embodiment of the invention also has an excellent display effect under the condition that a polaroid is not used, so that the thickness of the display module and the power consumption of the display module are reduced.
