A display panel includes a light-emitting substrate, an encapsulation layer, and a color filter substrate. The encapsulation layer includes at least a first nano-stack layer for reflecting light emitted from the color filter substrate. The first nano-stack layer includes a first inorganic layer and a first organic layer disposed in a stack arrangement, and the first organic layer having a refractive index less than a refractive index of the first inorganic layer. By using at least one first nano-stack provided in the encapsulation layer to reflect red and/or green light emitted from the color filter substrate, the present invention can reduce light loss of the red light quantum dot conversion unit and the green light quantum dot conversion unit due to scattering, and improve light output efficiency.
