Abstract: A display panel includes a light-emitting device on a substrate and an encapsulation structure on a light output surface on one side of the light-emitting device. The encapsulation structure includes a first inorganic layer and a fluoro-polymeric layer. Ductility and bending resistance of the fluoro-polymeric layer are greater than those of the first inorganic layer. Defects between the fluoro-polymeric layer and the first inorganic layer are fewer than those between the first inorganic layer and another layer.
