Method of manufacturing ultra-thin antireflection sticker and ultra-thin antireflection sticker

A method of manufacturing an ultra-thin antireflection sticker, comprising:

• a master mold manufacturing step in which a master mold having a plurality of semi- spherical mold structures on an upper surface thereof is manufactured;
• a sticker material coating step in which a sticker material comprising a perfluorinated polyether (PEPE) is coated onto the upper surface of the master mold;
• a cured film covering step in which a cured film is disposed to cover an entire area of a upper surface of the sticker material;
• a curing step in which the sticker material is cured;
• a cured film removal step in which the cured film is removed from the sticker material;
• and
• a sticker peeling step in which the cured sticker material is peeled off the master mold, the peeled-off sticker material forming a monolayer-structured ultra-thin antireflection sticker comprising a flat base and a plurality of antireflection structures protruding from an upper surface of the flat base to form semi-spherical groove shapes,
• wherein the ultra-thin antireflection sticker has a total thickness of about 20 μm and the flat base and the antireflection structures are integrally formed of a same material.
