The projection-type color display device of the invention includes: a white light source (1); a splitting means (4) for splitting white light emitted from the white light source into a first, a second, and a third beam having respectively different wavelength regions; a modulation means (8) for modulating the first, the second and the third beams; an irradiation means (4) for irradiating the first, the second and the third beams onto a principal surface of the modulation means at respectively different angles; and a projection means (10) for projecting the first, the second and the third beams modulated by the modulation means. In the projection-type color display device, the first beam includes a color beam having a weakest intensity among the beams in three primary colors contained in the white light; and a direction of the first beam incident onto the principal surface of the modulation means is closer to a normal of the principal surface of the modulation means as compared with the second and the third beams. <IMAGE> |
