Claim:
1. A method for pixel patterning and pixel position inspection of an organic light-emitting display device, the method comprising: forming, on a substrate using a first mask, a thin film layer of a first color corresponding to a first pixel pattern in an active area of the organic light-emitting display device and a first pixel positioning pattern for inspecting a position of a first pixel in a dummy area of the organic light-emitting display device, the dummy area being disposed outside the active area; 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 in the active area and another first pixel positioning pattern for inspecting a position of a second pixel in the dummy area.
