Abstract
The present invention relates to a nano-protrusion forming method and a base material having a nano-protrusion surface formed by the method. The method includes forming an anti-reflective layer including nano-protrusions having a width of several nm to several tens of nm, and/or an anti-glare layer including protrusions having a width of several tens of nm to several μm, by a wet etching process using an acid solution without using a nano-mask.
