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.

Abstract: A method for manufacturing a polarizer may include forming a first barrier and a second barrier on a surface of a metal layer. The method may further include providing a copolymer layer between the first barrier and the second barrier. The method may further include processing the copolymer layer to form a processed polymer layer that includes first-polymer portions and second-polymer portions that are alternately disposed. The method may further include removing the second-polymer portions from the processed polymer layer to form polymer members that are spaced from each other. The method may further include etching the metal layer, using at least the polymer members, the first barrier, and the second barrier as a mask, to form a plurality of first-type wires and a plurality of second-type wires.
