A method for pixel patterning and pixel position inspection of an organic light-emitting display device includes: forming, on a substrate using a first mask, a thin film layer of a first color corresponding to a first pixel pattern and a first pixel positioning pattern for inspecting a position of a first pixel; shifting, by a determined pitch, the first mask from a position associated with forming the thin film layer of the first color; aligning the shifted first mask with respect to the substrate; and forming, on the substrate using the shifted first mask, a thin film layer of a second color corresponding to the first pixel pattern and another first pixel positioning pattern for inspecting a position of a second pixel.

Masks, method to inspect and adjust mask position, and method to pattern pixels of organic light-emitting display device utilizing the masks

Masks, method to inspect and adjust mask positon, and method to pattern pixels of organic light-emitting display device utilizing the masks

A mask assembly for thin film deposition, the mask assembly, including a mask frame having an opening; a mask coupled to the mask frame and having a first surface facing a substrate and a second surface opposite to the first surface, a plurality of deposition pattern portions, and a rib between the adjacent deposition pattern portions, the mask having a partially etched area, the plurality of deposition pattern portions being within the partially etched area; and a partial etching extension portion in an outer portion of an area corresponding to the plurality of deposition pattern portions.
