A flat panel display device and a data signal generating method thereof are disclosed, in which data signals are different in voltage levels, thereby enhancing efficiency of representing a gray level and reducing power consumption. The flat panel display device includes: a display region (100) for receiving a data signal and a scan signal to display an image; a data driver (200) for generating the data signal based on a video signal and for supplying the data signal to the display region; and a scan driver (300) for generating the scan signal and for supplying the scan signal to the display region, wherein the data driver is adapted to adjust a voltage level of the data signal by at least one upper bit of the video signal and to adjust a pulse width of the data signal by at least one lower bit of the video signal to control brightness.
