The invention provides a display panel and a preparation method thereof. The display panel comprises a substrate and a thin film packaging layer, wherein the thin film packaging layer comprises a first inorganic layer, an organic layer and a laminated film layer. The preparation method for the display panel comprises a substrate providing step and a thin film packaging layer preparing step. The thin film packaging layer preparing step comprises a first inorganic layer packaging substep, a laminated film layer packaging substep, an organic layer packaging substep and a second inorganic layer packaging substep. The invention provides a display panel and a preparation method thereof. The patterned surface is arranged on the surface of the organic layer, so that the stress release capability of the film layer of the patterned surface is improved, the risk that the thin film packaging layer is broken in the bending process of the display panel is reduced, and the reliability of the thin film packaging layer and th
