  • Patent number: 9616461
    Abstract: Discussed are a roll mold, a method for fabricating the same and a method for fabricating a thin film pattern using the same, which can prevent dimensional variation of the mold and simplify the overall process. The method for fabricating a thin film pattern includes providing a roll mold having a base roller provided with a light source, an adhesive resin layer formed on the base roller, a buffer layer formed on the adhesive resin layer, and a mold surface layer having a groove-protrusion shape formed on the buffer layer; forming a printing liquid on the roll mold or the substrate; and rolling the roll mold over the substrate to form a thin film pattern on the substrate. Also, the mold surface layer and the adhesive resin layer can be cured through light emitted from the light source arranged in the base roller.
