Image display device

Abstract

The present invention relates to an image display device that is suitably applicable to, for example, a projector using an ultrahigh-pressure mercury lamp as a light source. In a light source of the present invention, main light is partially replaced with auxiliary light in a wavelength region in which the intensity of the main light is less than that of the auxiliary light. That is, the light source includes an illumination-light combining member that generates illumination light by strengthening the wavelength region of the emission spectrum of the main light with the auxiliary light. Accordingly, the loss of main light is satisfactorily reduced, and the light intensity in the wavelength region in which the intensity of the main light is insufficient is compensated for. Further, light emitted from the main light source formed of a lamp or the like is efficiently utilized, and a bright image can thereby be displayed with high color reproducibility.
