Abstract:
The application provides a manufacturing method for a display panel, a display panel, and a display device. The manufacturing method includes: providing a substrate; forming a driving circuit layer on the substrate; forming a planarization layer on the side of the driving circuit layer facing away from the substrate; forming a composite material layer on the side of the planarization layer facing away from the substrate with a polymerization-induced phase separation method to the composite material layer including a polymer and liquid crystal phase molecules dispersed in the polymer; removing the liquid crystal phase molecules in the composite material layer to obtain an auxiliary structure layer, the side of the auxiliary structure layer facing away from the substrate having a plurality of protrusion structures; and forming a pixel structure on the side of the auxiliary structure layer facing away from the substrate, wherein the auxiliary structure layer makes the pixel structure uneven, and the pixel structure includes a first electrode, an organic light emitting material, and a second electrode that are sequentially formed on the side of the auxiliary structure layer facing away from the substrate.
