The present invention provides a color image display device which improves color reappearance performance by a color filter consisting of RGB and YMC6. The invention comprises a display faceplate with the color filter which forms one pixel area with red, green, blue, yellow, fuchsin and cyan color filter areas, a color calculating part which generates a six-color signal comprising red, green, blue, yellow, fuchsin and cyan signals based on a RGB signal input from outside and a control part which controls the display of each color filter area of the display faceplate based on the six-color signal and displays an image corresponding to the RGB signal at the display faceplate. Except the red, green and blue color filter areas, the present invention is also provided with the yellow, fuchsin and cyan color filter areas, and one pixel area is formed by the areas, which can enlarge the color display range. Besides, even if an input image datum is the RGB signal, the yellow, fuchsin and cyan signals can also be generated and are displayed by the six-color signal, and the general RGB signal can also be used.
