Abstract
An organic light-emitting display panel including: an array substrate, an organic light-emitting element placed on the array substrate and comprising light-emitting pixels, and an encapsulation layer placed on a side of the organic light-emitting element away from the array substrate; the encapsulation layer comprises a first inorganic encapsulation layer having a thickness 10 nm˜100 nm, a first interlayer bonding layer, and a first organic encapsulation layer along a direction away from the array substrate; refractive indexes of the first inorganic encapsulation layer, the first interlayer bonding layer, and the first organic encapsulation layer are n, nand n, respectively; the refractive index ndecreases in gradient along a direction from the first inorganic encapsulation layer toward the first organic encapsulation layer, maximum and minimum refractive indexes of the first interlayer bonding layer are nand n, respectively; n>n, n<n
