The color reproduction correction circuit which corrects the color distortion caused when color signals using the first combination of the three primary colors are reproduced in a color display of the second combination of the different primary color sources has been disclosed, wherein: a provided color correction circuit generates the mixed color signal by multiplying the color signal in question by the specified coefficients and adding the mixed color signal to other color signals; the mixed colors in the second combination are used as primary color light sources in the second combination; the specified coefficients are determined so that these mixed color light sources are made close to the coordinates of the primary color light sources of the first combination; and the luminescent chromaticity values of the three primary colors are corrected so that the chromaticity values of the device match those specified by the signal system.
