A color display device has an evacuated vessel accommodating at least an electron-beam generating source in which a plurality of surface-conduction electron emitting devices are arrayed on a substrate, and phosphors for the three primary colors red, green and blue for emitting light in response to being irradiated with electron beams from the electron-beam generating source. A modulator is provided to modulate the electron beams, which irradiate the phosphors, based upon an image signal, the modulator having .gamma.-corrector for subjecting the image signal to a gamma correction. The modulator modulates the electron beams based upon the image signal corrected in advance by the .gamma.-corrector.
