A projection-type display device (20) for displaying an image using a projector device emitting optical images spatially modulated by reflection-type liquid crystal panels (31B, 31R, 31G) onto a screen (34), wherein phase difference plates (32B, 32R, 32G) are arranged at the incidence planes of the reflection-type liquid panels (31B, 31R, 31G) so as to cancel out the retardation comprised of the retardation corresponding to one-quarter of the wavelength of the incident light due to the polarization beam splitter (29) plus the retardations due to the dichroic mirrors (30B, 30R) of the color separating and synthesizing means, whereby it is possible to make the illumination light leaking from the polarization beam splitter (29) to the projection lens (33) at the black level portions extremely small and possible to prevent a reduction in the contrast due to the haze phenomenon. <IMAGE> |
