A display device includes a substrate including a display area and a non-display area adjacent to the display area. The non-display area includes a blocking region. An organic layer is disposed on the substrate. An emission layer is disposed in the display area of the substrate. An auxiliary pattern is disposed in the blocking region of the non-display area of the substrate. A thin film encapsulation layer is disposed on the substrate and overlaps the emission layer and the blocking region. The organic layer has a groove penetrating an entire thickness of the organic layer in the blocking region. The auxiliary pattern overlaps the groove. The auxiliary pattern includes a same material as a gate electrode disposed in the display area of the substrate.

A photo-mask is capable of preventing stain defects and a method for fabricating a liquid crystal display device using the photo-mask which achieves the same capability. The photo-mask includes a transparent substrate configured to transmit ultraviolet light and a light shielding layer configured to block ultraviolet light on a surface of the transparent substrate. The light shielding layer includes an absorption layer configured to absorb ultraviolet light.
