Abstract:
The present invention relates to a flat panel display device comprising a polysilicon thin film transistor and a method of manufacturing the same. Grain sizes of polysilicon grains formed in active channel regions of thin film transistors of a driving circuit portion and a pixel portion of the flat panel display device are different from each other. Further, the flat panel display device comprising P-type and N-type thin film transistors having different particle shapes from each other.
