Claim:
1. An image display device that displays an image, comprising: a plurality of light transmitting units having transmission wavelength characteristics respectively corresponding to a plurality of colors including a green color; an illuminating unit configured to emit light corresponding to each of the plurality of colors, the illuminating unit being configured to emit, with respect to at least the green color, light of a plurality of emission spectra including first light and second light (a) whose emission peak wavelengths are both within a range of the transmission wavelength characteristics of a light transmitting unit corresponding to the green color and (b) whose emission peak wavelengths differ from one another; and a control unit configured to control an intensity of light corresponding to the green color emitted by the illuminating unit in accordance with color characteristics of the image, wherein peak wavelengths and intensities of the first light and the second light are determined so as to reduce a fluctuation in stimulus of the green color when a color matching function corresponding to the green color fluctuates due to individual variability.
