摘要： A projection display device comprising three projection lenses arranged in a row in a side by side relationship and having respective optical axes extending toward a screen, and three liquid crystal display panels forming images of red, green and blue color lights, the liquid crystal display panels and the projection lenses being arranged to form sets individually. A mirror is arranged between the display element and the projection lens of at least one of the sets. Accordingly, one of the display elements is arranged so as to face in a first direction and the adjacent display element so as to face in a second direction. It is thus possible to reduce the distance between the adjacent projection lenses even if the size of the liquid crystal display panels is enlarged.

摘要： A projector comprising liquid crystal display panels and a projection lens for projecting the modulated light to a screen. A back surface reflection mirror including a transparent plastic sheet and a reflecting film is arranged between the projection lens and the screen. The mirror is thin and light and may have optical anisotropy. In order to eliminate an uneven pattern appearing in the screen caused by optical isotropy of the mirror and the difference between the light distribution characteristics in the screen for P- and S-polarized light, the projection lens and the back surface reflection mirror are arranged in such a relationship that a wave normal vector of an arbitrary component of the light projected by the projection lens and made incident to the back surface reflection mirror is not parallel to the optical axis of the plastic sheet.

摘要： A liquid crystal display device includes: a liquid crystal spatial modulating element holding a liquid crystal layer between a pair of parallel substrates, wherein transmission of light incident upon the liquid crystal layer along an incidence direction tilted to a predetermined direction from a normal to the substrates takes a local minimum as a voltage applied to the liquid crystal layer is changed, and the voltage at the local minimum changes as the incidence direction is changed; an illumination optical system for supplying illumination light generally over a whole surface of the liquid crystal spatial modulating element along incidence direction or directions tilted to the predetermined direction; and a driver circuit capable of applying a voltage across the liquid crystal layer, the voltage being generally equal to a voltage which provides the local minimum of the transmission with respect to the illumination light. The liquid crystal display device has uniform display characteristics over a display screen.
