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.

Disclosed is a display device that includes a substrate having an active area and a dead area around the active area; an alignment mark on the inside surface of the substrate in a part of the dead area; and a light-shielding pattern on a rear surface of the substrate in the dead area, the light-shielding pattern including a mark hole for exposing the alignment mark. By providing the light-shielding pattern on a display surface in the dead area, the display device has expanded active display area and improved visual appreciation.

Discussed are a roll mold, a method for fabricating the same and a method for fabricating a thin film pattern using the same, to prevent dimensional variation of the mold and simplify the overall process. The method for fabricating a roll mold includes providing a substrate provided with a master pattern layer, sequentially forming a mold surface layer and a solid suffer layer on the substrate provided with the master pattern layer to provide a flat panel mold, forming an adhesive resin layer on the base roller aligned on the flat panel mold, and rolling the base roller provided with the adhesive resin layer over the flat panel mold to adhere the flat panel mold to the base roller through the adhesive resin layer.

Disclosed is a method for fabricating a clich&#xe9; that can prevent formation of a defective thin film pattern, and a method for forming a thin film pattern using the same. The method for fabricating a clich&#xe9; includes providing a base substrate having first and second regions, forming a first depressed pattern having a first depth and a first width at a first region, and a second depressed pattern having a second width greater than the first width and a depth the same with the first depth at a second region, forming a protective film for exposing the second region and covering the first region, the protective film having adhesivity, forming the second depressed pattern to have a second depth deeper than the first depth of the first depressed pattern at the first region by using the protective film having the adhesivity, and removing the protective film.
