PURPOSE: To prevent color split in a field sequential color display. CONSTITUTION: A minimum value is detected from digitized R, G, B signals (three primary colors) for every pixel (a sample) in a minimum value detection circuit 5, and the minimum value is supplied to a four-fold speed signal processing circuit 9 as a Wht signal (achromatic signal). By subtracting the minimum value detected from the R, G, B signals, R', G', B' signals (modified three primary colors signals) are generated, and the modified three primary colors signals are supplied to the four-fold speed signal processing circuit 9. In the four-fold speed signal processing circuit 9, time-division multiplex in which horizontal and vertical synchronizing signals are made four-fold, is performed. By turning on (0 deg. rotation) and/or off (90 deg. rotation)πcells 16, 18 based on the time-division multiplex signal, a color image of which one frame consists of four fields is obtained.
