Summary:The embodiment of the invention discloses a display panel, a preparation method thereof and a display device. The display panel comprises a substrate; the pixel definition layer and the supporting columns are located on one side of the substrate; the pixel definition layer comprises a plurality of opening structures; the supporting columns are located on the side, away from the substrate, of the pixel defining layer, and the supporting columns and the opening structures are not overlapped in the direction perpendicular to the plane where the substrate is located; the height difference delta H between the highest points of the first surfaces of any two supporting columns is smaller than a first preset difference value; the first surfaces are the surfaces of the sides, away from the substrate, of the supporting columns. According to the technical scheme, it is ensured that the heights of the highest points of any two supporting columns are close, the heights of all the supporting columns are kept consistent, th
