摘要： A color liquid crystal display device which separates white light in to component colors. The separated colors are modulated by a reflective liquid crystal display. A lens group between the light separator and the reflective liquid crystal display condenses the entering light to each pixel of the liquid crystal display. High brightness and aperture efficiency are achieved by including in the lens group a birefringent material so that a different optical function is performed relative to the entering light fluxes and the modulated light fluxes.

摘要： Dichroic mirrors are disposed at the same inclination angle in a position such that a plane including an incidence optical path and a reflection optical path (transmission optical path of green light) of blue light reflected at a reflecting surface of one dichroic mirror is orthogonal to a plane including an incidence optical path and a reflection optical path of red light reflected at the other dichroic mirror. The other dichroic mirror is formed by cementing two glass substrates, and a red light reflecting layer is formed on the joint surface.

摘要： An illumination optical system has a light source that emits white light having random polarization planes, a polarization separation device that separates the light from the light source into two types of light having polarization planes perpendicular to each other and traveling in directions at an angle to each other, a wavelength-specific polarization conversion device that receives the two types of light thus separated and that then subjects the light of a particular wavelength range included in them to polarization conversion, a convergence optical system that receives the two types of light after the light of the particular wavelength range included therein has undergone polarization conversion and that then makes them converge on different convergence positions, and a half-wave plate disposed near one of those convergence positions. This illumination optical system outputs white light that has different polarization planes in a particular wavelength range and in other wavelength ranges, and thus, when the light is subjected to color separation by being separated into light of the particular wavelength range and light of other wavelength ranges, the difference of the polarization planes serves to prevent loss of the amount of light.

摘要： In a zoom lens system that consists of a plurality of lens units and that performs zooming by varying the distances between the lens units, one of the lens units other than the lens unit disposed at the object side end includes a hand-shake correction lens unit that is decentered in a direction perpendicular to the optical axis for hand-shake correction and a fixed lens unit that is disposed on the image side of the hand-shake correction lens unit and that is kept in a fixed position during hand-shake correction. With respect to the lens element disposed at the image-side end of the hand-shake correction lens unit and the lens element disposed next to the image-side surface of the former lens element and kept in a fixed position during hand-shake correction, the relations between their shape factors and refractive powers are defined.

摘要： A projector has an illumination optical system, a reflection-type display panel, a projection optical system, and light-introducing device. The display panel is illuminated by the illumination light emitted from the illumination optical system and is divided into a plurality of pixels to reflect the incoming illumination light selectively in accordance with the pattern formed by those pixels and thereby produce projection light. The projection optical system transmits the projection light reflected from the display panel to project the pattern formed by the pixels onto a projection plane on which to form a projected image, and is composed of, from the projected-image side, a front lens unit, an aperture stop, and a rear lens unit. The light-introducing device is disposed between the front and rear lens units and directs the illumination light to the display panel. The projection optical system fulfills the condition 0.2≦&ggr;F≦0.8 where &ggr;F represents the angular magnification of the front lens unit.
