摘要： A thin film packaging structure and a display panel are provided. The thin film packaging structure includes: a first inorganic packaging layer for covering a device to be packaged; an organic packaging layer provided at a side of the first inorganic packaging layer; a second inorganic packaging layer provided at a side of the organic packaging layer facing away from the first inorganic packaging layer; and at least one first inorganic adjusting layer provided at a side of the first inorganic packaging layer facing away from the device to be packaged; and an oxygen content of the at least one first inorganic adjusting layer is greater than an oxygen content of the first inorganic packaging layer and/or the second inorganic packaging layer. The thin film packaging structure increases the stability of the thin film packaging structure in the bending process, avoids the breakage of the thin film packaging structure or the separation between the film layers of the thin film packaging structure, ensures the packaging stability of the thin film packaging structure, and thus improves the bending performance and service life of the display panel.
