摘要： A liquid crystal projector comprises an illuminating optical system including a light source, a color separating optical system for separating illuminating light rays emitted by the illuminating optical system into light rays of three colors, a projection lens unit comprising a projection lens, a cross dichroic prism disposed near a light receiving end of the projection lens, and a plurality of liquid crystal panels arranged around the cross dichroic prism, and a light source power supply for supplying power to the light source. The projection lens unit, the color separating optical system, the illuminating optical system and the light source power supply are arranged in that order. The liquid crystal projector has an outside size in a horizontal plane of 263 mm by 318 mm or below. The liquid crystal panels have a display screen size of 0.9 in. A cooling fan for cooling the plurality of liquid crystal panels is disposed beside the projection lens.

摘要： The purpose of the present invention is to provide a projection image display device in which all of the multiple light sources to be used are positioned optimally, regardless of the mode of installation of the device. This projection image display device has two illumination optical systems (1, 2) that are each provided with a light source (111, 211), a color separator for separating into three colors of light, a liquid crystal panel (150, 250) for forming an optical image, and a color synthesis prism (160, 260) for color-synthesizing. A polarization beam splitter (3) for synthesis synthesizes an optical image formed by the illumination optical system (1, 2), and projects the same from a projection lens (4). The optical axis (101, 201) of each light source (111, 211) is positioned within the same plane as the optical axis (401) of the projection lens (4), and so as to orthogonally intersect the optical axis (401) of the projection lens.
