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

A mask frame assembly includes: a mask including a deposition pattern through which a deposition material is deposited to a deposition target; a frame to which the mask comprising the deposition pattern is combined; and a pattern position adjusting mechanism which is coupled to the frame and configured to apply a force to the frame such that a position of the deposition pattern of the mask combined to the frame is changed.
