Abstract
A method of manufacturing a mold includes following steps. Providing a solution, which includes a solvent, a solute and a plurality of nanoparticles. Providing a first substrate. Spin coating the solution on the first substrate, and then vaporizing the solvent to form a first mold on the first substrate. Thus, an upper surface of the first mold has a plurality of first porous structures. The present invention further includes forming an optical film having protrusion patterns with the aforementioned mold.
