a method for fabricating a mold includes the steps of forming a photo - polymerizable resin layer between a master substrate and a transparent mold substrate , wherein a first pattern is formed on the master substrate ; solidifying the resin layer by exposing the resin layer to a uv light through the transparent mold substrate ; and forming a mold having a second pattern by separating the resin layer from the master substrate , wherein the second pattern is in a form of a recess on the resin layer at a portion corresponding to the first pattern and the resin layer being engaged with the mold substrate .
