    摘要: The present disclosure relates to a display panel and a display device thereof. The display panel includes: a substrate; an organic light-emitting device located on the substrate; a cover layer located on the organic light-emitting device; a light extraction layer located on the cover layer; an optical functional layer located on the light extraction layer; and an encapsulation layer located on the optical functional layer. A refractive index of the light extraction layer is less than a refractive index of the cover layer and less than a refractive index of a portion of the encapsulation layer closest to the optical functional layer. A refractive index of the optical functional layer is less than the refractive index of the portion of the encapsulation layer closest to the optical functional layer and not equal to the refractive index of the light extraction layer.
