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.

摘要： A projection type image display device using, in a projection optical system thereof, a flat mirror, which is easy to design and manufacture, as a projection mirror is provided. The projection optical system is a diagonal projection optical system and includes plural lenses. Among the plural lenses, the one disposed closest to the flat mirror has an effective area, along the vertical direction of an image, through which a light beam passes and which is off the optical axis, among optical axes of the plural lenses, shared by the most lenses so as not to allow light reflected from the projection mirror to return to the projector body. A polarization converter using, for example, a quarter wavelength plate is provided at an output surface of a crossed prism to decrease reflectance differences between differently colored light and to thereby prevent the occurrence of color unevenness.
