摘要： In an optical system phase device such as .lambda./2 plate or a .lambda./4 plate is used to convert S polarization to P polarization and vice versa. In the projection display, a white light emitted from a light source is separated by a color separation optical system, including dichroic mirrors or a dichroic prism, into three primary colors which are modulated by optical modulation elements. Then, the modulated lights are synthesized by a color synthesis optical system and projected by a projection element onto a screen. When appropriate plates are inserted appropriately in the optical system of the projection display, the conversion between S and P polarization occurs and an optical bandwidth becomes narrow, and color purity can be improved. A thick transparent plate is preferably adhered to the optical modulation element. A light absorption film is applied to an ineffective plane of the transparent plate. The phase device is preferably inserted between an optical modulation element and a transparent plate or the like to improve contrast. The invention can be applied to liquid crystal panels such as liquid crystal/resin display panels, light beam writing type display panel or micro mirror display panel. Preferably, the phase device is set to be rotatable so as to adjust contrast appropriately.

Polarizing plates are disposed on the incident side and the outgoing side of a liquid crystal cell so that a twisted nematic liquid crystal is arranged to become approximately 90.degree. in twist angle between two transparent substrates having a picture element electrode.

摘要： A light valve includes a light valve layer for forming an optical image as variations in its ability to scatter light, and two substrates between which the light valve layer is sandwiched and at least one of which is transparent. The light valve satisfies the following condition: ##EQU1## where t denotes a central thickness of the at least one of the substrates, n denotes a refractive index of the at least one of the substrates and d denotes a maximum diameter of an effective display area of the light valve layer. Alternatively, a transparent plate can be optically coupled to one of the substrates by a transparent body. In this case, the same condition is satisfied except that the thickness refers to a central thickness from a face of the transparent plate remote from the transparent body to the light valve layer.

摘要： A viewfinder suited for use in a video camera, wherein rays of light emitted at a large solid angle from a minute light emitting area of a light emitting element are converted by a condenser lens into a bundle of generally parallel rays of light having a narrow directionality before they enter a liquid crystal display. The liquid crystal display modulates the rays of light emerging from the condenser lens according to a video signal to effect an image display. The displayed image is magnified by a magnifying lens. The liquid crystal display is of a type wherein an optical image is formed as a function of a change in state of light scattering and may be a polymer dispersed liquid crystal display, a liquid crystal panel utilizing a dynamic scattering mode, a ferro-electric liquid crystal panel using a scattering mode or a display panel utilizing PLZT.
