ABSTRACT:
A projection-type display device100including a light source10, a luminance modulation light valve having a plurality of pixels capable of independently controlling a transmission factor T1, dichroic mirrors44aand44bthat divided the light from the luminance modulation light valve into the three primary colors of red, green and blue, a plurality of color modulation light valves into which light divided with dichroic mirrors44aand44brespectively enters and have a plurality of pixels capable of independently controlling a transmission factor T2, and a dichroic prism48that synthesizes light from each of the color modulation light valves, and is provided with a relay optical system16on the light path of a luminance modulation section14and a color modulation section18that forms an optical image of the luminance modulation light valve on the pixel surfaces of each of the color modulation light valves.
