Abstract: 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.

Abstract: A mask frame assembly including a frame including a first opening, a first mask including second openings that each has an area smaller than the first opening and a first surface having portions of the first surface connected to the frame. The mask frame assembly includes second masks disposed on a second surface of the first mask extending across the first opening in a first direction and arranged in a second direction that is substantially perpendicular. The second masks include pattern parts having a shape corresponding to the second openings. The pattern parts each include pattern holes configured to allow a deposition material to pass through. The second masks include a rib part disposed between the pattern parts. The rib part includes dummy holes each having an area greater than each of the pattern holes. The first mask is configured to block the deposition material passing through the dummy holes.
