In an image display method for providing display in a predetermined color order using a plurality of color signals of image data for an electro-optical modulation device which modulates light emitted from a light source in accordance with signals, color distribution ratios for the plural color signals are established such that errors caused due to response delays of the electro-optical modulation device from the color signals can be reduced to the minimum value or almost the minimum value at the time of display in the predetermined color order.
