1. A display panel comprising:
a substrate;
a light-emitting element, disposed on the substrate;
an encapsulation layer, disposed on a side of the light-emitting element away from the substrate, wherein the encapsulation layer comprises a first inorganic film layer, a first auxiliary film layer and an organic film layer that are stacked on the light-emitting element, an absolute value of a difference between a refractive index of the first inorganic film layer and a refractive index of the first auxiliary film layer is less than or equal to 0.05, and an extinction coefficient of the first auxiliary film layer for visible light is less than an extinction coefficient of the first inorganic film layer for visible light.
