To solve such problems that in a color sequential image display device, as the brightness of a displayed grayscale is linearly proportional to the reflection period of light, the number of grayscales in an image substantially displayed by grayscale conversion is decreased, and that when the number of color images increases in order to increase the color reproduction range, a period of displaying each color image is reduced to darken a pure color.
At least one color image in a plurality of color images sequentially displayed in order to form a color image is displayed by synthesizing light (R1) in a first wavelength region and light (R2) in a second wavelength region, wherein the second wavelength region contains at least a part of the first wavelength region and a different wavelength region (R2n) continuous to the included wavelength region.
