Claim 9:
10. A preparation method of a display panel, comprising:
forming an electroluminescent device on a display area of a base substrate;
forming a first inorganic packaging layer, an organic packaging layer, and a second inorganic packaging layer sequentially on the electroluminescent device to form a packaging structure;
wherein the first inorganic packaging layer and the second inorganic packaging layer extend from the display area to an isolation area and a hole area located at the display area, the first inorganic packaging layer is in direct contact with the base substrate in the hole area, orthographic projections of the first inorganic packaging layer and the second inorganic packaging layer on the base substrate cover an orthographic projection of the hole area on the base substrate, and an orthographic projection of the organic packaging layer on the base substrate does not overlap the orthographic projection of the hole area on the base substrate; and

forming an organic layer at a side, facing away from the base substrate, of the second inorganic packaging layer in the isolation area between the display area and the hole area, wherein the organic layer is disposed at a side, close to the hole area, of the organic packaging layer; and the display area and the isolation area surround the hole area.
