There is provided a process of making a mold for optical films. The process of making a mold for optical films comprises: etchinga stereostructure in a surface of the mold having a flat surface or an engraved convex and concave surface, by using a laser beam. The process of making a mold for optical films may be useful to easily mark spots, to control the height of protrusions and the position where the protrusions are formed, and also to form the protrusions having constant depths even in a curved surface such as a convex and concave surface.
