The invention discloses a display panel and a preparation method of the display panel. The display panel comprises a substrate; the light-emitting elements are arranged on one side of the substrate base plate, the light-emitting elements are provided with first surfaces deviating from the substrate base plate, and the heights of the first surfaces of at least part of the light-emitting elements are different in the direction perpendicular to the plane where the substrate base plate is located; the light-transmitting heightening layer is arranged on one side of the first surfaces of the light-emitting elements except the highest light-emitting element and forms a second surface, so that the second surface, away from the substrate, of the light-transmitting heightening layer is flush with the first surface of the highest light-emitting element in the direction perpendicular to the plane where the substrate is located. According to the display panel, the light-transmitting heightening layer is arranged on one si
