PROBLEM TO BE SOLVED: To provide a field emission display device and its driving method for preventing the occurrence of color deviation in a process of adjusting a cathode voltage and a gate voltage corresponding to a digital video signal input to one frame section. SOLUTION: The field emission display device includes: a pixel part 100 including a plurality of pixels 101 emitting light by applying prescribed voltages to gate electrodes Gm (m is a natural number) and cathode electrodes Cn (n is a natural number); a data driving part 200 for generating a data signal by receiving transmission of a video signal and transmitting it to the pixel part 100; a scanning driving part 300 for generating a scanning signal and transmitting it to the pixel part 100; and a color adjustment part 400 for adjusting the voltage of the gate electrodes Gm corresponding to the video signal, correcting the video signal corresponding to light emission rates of red, blue, and green pixels 101 according to the variation of the voltages of the gate electrodes Gm, and transmitting it to the data driving part 200.
