Abstract
A method of fabricating a polycrystalline silicon thin film for a thin film transistor (TFT), a mask pattern used for the method, and a method of fabricating a flat panel display device using the method and the mask pattern. In one embodiment, a mask pattern includes a plurality of regions, each of the regions having at least one of one or more transparent portions or one or more non-transparent portions. A total area of the one or more transparent portions and the one or more non-transparent portions in one of the regions is substantially equal to a total area of the one or more transparent portions and the one or more non-transparent portions in at least one other of the regions. A total area of the transparent portions in the mask pattern is different from a total area of the non-transparent portions in the mask pattern.
