PROBLEM TO BE SOLVED: To provide an electron emission display (EED) device for adjusting a pulse width of data signal according to an active pulse width of a horizontal synchronization signal. SOLUTION: The EED device constituted so that a display data signal obtained by modulating a pulse width of video data by a data driving section is outputted to an EED panel according to a scan signal of a scan driving section includes: a reference signal memory stored with a lookup table of reference signals corresponding to active pulse widths of horizontal synchronization signals defined by a system clock and the active pulse widths of the horizontal synchronization signals; a reference signal reference unit for outputting a reference signal in accordance with the lookup table stored in the reference signal memory; and a gray level signal generator for counting the reference signal and outputting a gray level signal to the data driver, wherein the data driving section outputs video data corresponding to the gray level signal, to data electrode lines of the EED panel.
