1. A display panel, comprising:
a light emitting element; and
an encapsulation layer on the light emitting element, wherein the encapsulation layer covers the light emitting element,
wherein the encapsulation layer includes a plurality of polymer layers including a block copolymer,
wherein the plurality of polymer layers include:
a plurality of first polymer layers, each of which has a first refractive index; and
a plurality of second polymer layers, each of which has a second refractive index greater than the first refractive index, wherein the plurality of first polymer layers and the plurality of second polymer layers are alternately stacked one on another,
wherein a difference between the first refractive index and the second refractive index is in a range of about 0.1 to about 0.6,
wherein a transmittance of light in a wavelength range of about 400 nm to about 420 nm in the encapsulation layer is about 10% or less.
