1. A flat panel display comprising R, G and B unit pixels, wherein at least one unit pixel of the R, G and B unit pixels includes at least a switching transistor comprising a first gate region, and a driving transistor comprising a second gate region,
wherein the first gate region is a channel region under a gate electrode of the switching transistor, and the second gate region is an offset region between two channel regions under a gate electrode of the driving transistor as well as the two channel regions, and
wherein the resistance value of the first gate region is different from a resistance value of the second gate region.
