摘要： An illuminating optical system propagates a coherent light flux from at least one light source into a predetermined optical path to guide the light flux to a screen. A light bulb forms an image to be displayed on the screen on an illumination area illuminated with the light flux that is guided by the illuminating optical system. A projecting optical unit projects the image that is formed on the illumination area onto the screen in a magnifying manner. The illuminating optical system includes a diffusing unit that diffuses the light flux from the light source near a focusing position of the illuminating optical system.

摘要： A projection display device has an illumination optical system that includes a light-intensity equalization element, a first optical system, and an aperture regulation member. The aperture regulation member is disposed at a position that is not optically conjugate with the screen, and the aperture regulation member has at least one of the following, using measured or calculated relative illuminances at each of multiple segments of the image formation region or screen: an aperture expansion part provided at a position corresponding to a segment with a low relative illuminance, the aperture expansion part being a cutout that narrows the light-blocking section and widens the aperture section; an aperture contraction part provided at a position corresponding to a segment with a high relative illuminance, the aperture contraction part being a protrusion that widens the light-blocking section and narrows the aperture section.
