Abstract: A display panel includes a light emitting element and an encapsulation layer on the light emitting element. The encapsulation layer covers the light emitting element. The encapsulation layer includes a plurality of polymer layers including a block copolymer. The plurality of polymer layers includes 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. A difference between the first refractive index and the second refractive index is in a range of about 0.1 to about 0.6.
